Sony launches A99II at photokina

Sony has today released the details of the updated A99II, using a 42MP sensor and 5-axis stabilisation to match the A7RII. It does not appear to have retained GPS and the paragraph highlighted in red later on indicates a weasel-worded possible get out for this – it may not embed GPS in the image files, but instead store a mobile phone location data track on the camera’s memory card. We may guess that this choice could be partly down to cutting out fees payable to incorporate a GPS module. Not the same, guys, not the same:

From Sony’s site, the ambiguous word is highlighted here:

Use Location Information Link to make the most of your camera anywhere you go together. After the camera has been paired to the PlayMemories Mobile app installed on a compatible mobile phone or tablet device, it can acquire location data from the mobile device and record that data with still images. The acquired location data can also be used to correct the camera’s date/time and location settings. The PlayMemories Home application can then be utilised on a personal computer to organise still images imported into the computer on a map.

Edit: note that Sony’s later announcement for A6500 uses specific wording which says that its GPS Blueooth app embeds location data in the images as they are shot. This wording has not been used for A99II. We have not, though the A9II has now been released and bought by some users, been able to confirm how it works yet.

In the Sony release (used almost complete, slightly edited, to form this post) they appear to imply that dual SD card slots are new, which of course they are not, the original A99 has this already. No UHS-II, no USB 3 Not only that, the dual slots are apparently exactly the same spec as the original unless someone at Sony Towers has forgotten to edit their website:

Memory Stick PRO Duo, Memory Stick PRO-HG Duo, Memory Stick Micro (M2), SD memory card, SDHC memory card (UHS-I compliant), SDXC memory card (UHS-I compliant), Micro SD memory card, Micro SDHC memory card, Micro SDXC memory card

Some of the hidden, clever features of the A99 remain like the buttons which are coded to touch with concave or convex tops or a small raised dot, making it easy once you have learned their feel to find them by fingertip. In fact the entire interface remains constant (in the way that Canon did throughout the EOS 1D series) meaning you can pick this up and shoot immediately, coming fom the A99. Only the Silent Controller is significantly improved, and the badly placed Movie button remains exactly where it was.

  • Full-frame 4D Focus: Innovative Hybrid Phase Detection AF system with accurate 79 hybrid cross AF points[i] enabled by 79-point dedicated and 399-point focal-plane AF sensors and continuous shooting at up to 12fps[ii]
    There is no AF Illuminator, but please note that -4 EV is quoted with an f/2.8 lens at ISO 100. In the past, AF low limits were always quoted with an f/1.4 lens (although the sensor only works at f/2.8). This is very good.
  • 42.4 effective MP 35mm Full-frame Exmor R™ CMOS sensor so it’s essentially an A7RII
  • Newly developed optical 5-axis in-body image stabilisation system
  • Outstanding operability and reliability in newly designed downsized body
  • Internal 4K movie recording in XAVC-S format[iii] with host of pro-orientated movie features
    IMPORTANT: this appears to be a Super-35 4K mode if you want no pixel binning and the highest overall quality but near-full-frame is offered with the usual partial readout.We would add a few extras – this camera has the much-needed (almost essential) Copyright Info function, minimum shutter speed when using Auto ISO, 10/5/2 sec self-timer, Hi+ in addition to Hi, Med and Lo motordrive shooting (not just shifting three settings over a faster range but giving 12, 8, 6 or 4 fps); built-in WiFi wireless including WiFi remote control and NFC (but not, apparently, apps); there are new Highlight and Average metering modes, and for each metering mode, you can calibrate the standard exposure if you prefer your shots slightly lighter or darker than the camera’s default.The A99II can capture 54 uncompressed RAW+JPEG images at 12fps (Hi+) before the buffer is full. There’s no great advantage in capturing RAW only, or JPEG only, and even with Fine JPEG at Hi speed (8fps) the limit is still 71, not ‘until card full’.

    Omissions include no Multi Shot Noise reduction, no GPS, and the external DC power supply is no longer via a dedicated socket, instead it uses the dummy battery approach. The camera is still not officially recommended for use in temperatures below freezing or over 40°C/104°F, both of which can easily be achieved in Scotland in a single sunny winter day (even without the benefit of your car parcel shelf oven).

The upgraded autofocus

The newly developed Phase Detection AF System is capable of ‘full-time AF’ and is the first implementation of 4D FOCUS in the full-frame ɑ series, bringing a supreme new level of AF performance to ɑ99 II users. The Hybrid Phase Detection AF System is enabled by combining a precision 79-point[iv] dedicated phase detection AF sensor with 399 focal plane phase detection AF points to produce a 79 hybrid cross AF point[v] array. These cross points deliver incredibly precise autofocus performance and advanced subject tracking of any moving objects right across the image, at high speed. In addition, as there is no moving mirror, TMT enables continuous AF operation and the finder image remains unaffected during any type of shooting, including live view and movie recording.

Low light conditions present no problem to the ɑ99 II. The precision AF system will function properly down to EV-4[vi] brightness levels where most other cameras struggle. Editor’s note: the A99 is poor in this respect and often can’t focus modest aperture lenses at all in low light.

Data flow through the ɑ99 II has been redesigned to allow for high resolution and continuous shooting at high frame rates. A new front-end LSI works with the image sensor and BIONZ X image processing engine, as well as a newly designed shutter unit, to enable continuous shooting at up to 12fps with AF/AE tracking[vii], all whilst harnessing the sensor’s 42.4MP capabilities. The result is an ultra-fast camera that will deliver incredibly detailed shots, even with fast moving objects in challenging light conditions. Thanks to a large buffer and sophisticated data processing, these shots can be viewed immediately after shooting even when in high speed continuous shooting mode and if shots are being taken indoors under artificial lighting, flicker is automatically detected and the shutter is timed to minimise its effect on the end image[viii].

Improvements to the EVF display algorithm now deliver continuous live-view shooting at up to 8 fps[ix] with AF/AE tracking with minimal display lag so that the viewing experience is essentially no different from that of an optical viewfinder. Exposure, white balance and other camera settings are displayed in real time in the viewfinder and continuous live view shooting can be set in 3 stages to match a variety of subjects: 8 fps, 6 fps and 4 fps.

Pixel Power

The back-illuminated full-frame 42.4MP[x] Exmor R CMOS sensor benefits from a gapless-on-chip design and allows for fast readout of large volumes of data as well as being extremely efficient in its light gathering ability. The net result is very high sensitivity with low noise, wide dynamic range and 42.4MP resolution across an ISO range of 100-25600, expandable to ISO 50 – 102,400[xi]. The ɑ99 II has been designed without an optical low-pass filter to allow the finest natural details and textures to be captured with unprecedented depth and realism and the photographer can select compressed or uncompressed RAW files, as required.

5-axis SteadyShot™ INSIDE Image Stabilisation

Having proved to be incredibly popular in the ɑ7 II series of cameras, Sony has designed a new in-body 5 axis image stabilisation system for A-mount cameras which debuts for the first time in the ɑ99 II. In addition to movement in the pitch and yaw axes that tend to occur at longer focal lengths, this system effectively detects and compensates for shift blur that can occur on the X and Y axes when shooting close-up, and roll blur that is often apparent in still images and movies that are shot at night. Newly implemented precision gyro sensors are capable of precisely detecting even tiny camera movements that can cause blurring, providing a 4.5 step[xii] shutter speed advantage that can help realise the full potential of the 42.4MP sensor, in both stills and movies. The effect of image stabilisation can be monitored in the viewfinder or on the LCD screen during live view when the shutter button is half pressed or the Focus Magnifier functions are used. This allows framing and focus to be accurately checked via live view when shooting at telephoto focal lengths or macro distances.

Improved design and operability

The design of the new ɑ99 II has noticeably evolved compared to its predecessor, based upon feedback from professional users. The new model is 8% smaller than the original ɑ99 and has a newly designed grip, magnesium alloy body, dual SD[xiii] card slot and other upgrades that improve both hold and operation. All major buttons and dials are provided with seals and the media jack cover and enclosure edges feature tongue and groove – the result is a body that is both dust and moisture resistant[xiv] and can be used in the toughest and most challenging shooting conditions.

In addition to being designed for faster response, the new shutter unit is also more durable and has passed endurance tests in excess of 300,000 shutter operations[xv].

The XGA OLED Tru-finder has a ZEISS® T* Coating and has a 4 element lens group that includes a double sided aspherical element whilst offering a powerful 0.78x magnification, delivering outstanding clarity from corner to corner. It also has a fluorine coating on the outer lens to prevent fingerprints, dust, water, oil and dirt from sticking, thus ensuring a clear view. Editor’s note: the ocular of the original A99 is a weak point, and in the A7RII Sony finally produced a really good non-squiffy eyepiece optical train which shows a clear view with some leeway to move your eye. So this is a major upgrade as much of the experience of using the SLT models comes down to finder quality.

The silent Multi Controller introduced in the original ɑ99 has been improved so that in addition to allowing control of aperture, shutter speed, ISO, exposure compensation, AF area, AF mode and other settings, it now features a click-stop ON/OFF switch. When ON, the preferred setting for still image shooting, the control clicks, providing a tactile indication of the length of rotation. When OFF, the control turns smoothly and quietly, ideal for movie shooting. Location data acquisition has also been made possible via Bluetooth[xvi] connection to a compatible mobile device and it is now possible to select whether the storage location should just be on a tethered computer or also on camera for easy review without leaving the shooting position. Based upon feedback from a number of ɑ users, the menu structure of the ɑ99 II has also been updated to deliver a smoother navigational experience.

Internal 4K movie at 100 Mpbs

The ɑ99 II enables internal 4K movie recording[xvii] featuring full pixel readout, without pixel binning[xviii], for ultimate high resolution video in the pro friendly XAVC S format. It is capable of recording high quality footage at 100Mbps for 4K recording. A new ‘Slow and Quick’ mode[xix] (S&Q) supports both slow motion and quick motion. Frame rates from 1 fps to 120 fps (100 fps) can be selected in 8 steps for up to 60x (50x) quick motion and 5x (4x) slow motion recording.[xx] A number of features designed for a professional movie production workflow are included such as picture profiles, time code and HDMI clear output and the new ɑ99 II now also offers gamma assist for real time S-Log monitoring and a zebra mode for easier exposure adjustment. S-Log3 and S-Log2 gamma are now included, making wide dynamic range shooting possible with(out) – our edit, the press release says with! blown highlights or blocked shadows making the ɑ99 II easily integratable into a fully professional movie production workflow.

Editor’s note: there’s a problem with the A99II for movies, which also applies to the LA-EA4 and SSM/SAM or other A-mount lenses on the E-mount bodies – the lenses really don’t work well at all. Sony had pictures of this camera with the 24mm f/2 SSM, still a current lens. I sold mine because it could not handle the same AF and exposure control functions as the 25mm f/2 Batis or the 28mm f/2 Sony (which I use) during video shooting. The A-mount was never built for movies, the E-mount has been from the start. However, both are fine using purely manual focus, manual aperture ciné lenses which many professionals prefer.

Alpha 3000 has NEX mount, 20 megapixel, APS-C

Posted on By

The long-rumoured Alpha 3000 was announced earlier in August but placed under a n embargo until August 27th. At the same time, the Press was given an insight into new smartphone related products (also widely rumoured) but again, not allowed to print anything officially.

The A3000 is a DSLR-like body with an electronic 1.44MP viewfinder in a prism-style top bulge, but the body is much slimmer at the lens mount and built to the smallest Alpha form factor as the 3 series indicates (smaller than the A57). Indeed, it’s not so different from the relationship of the very first Alpha 3000 series cameras back at the end of the 1980s. The mount is a regular NEX E-mount and the camera lacks any form of Phase Detection AF, depending on Contrast Detection matched to both existing (18-55mm SEL, etc) and new E-mount lenses. The rear screen is a 230KP fixed type.

18-105-16-70

Along with this first Alpha E-mount body, Sony announced three new E-mount lenses – a 50mm f/1.8 E OSS (£249) in black, CZ Vario-Tessar T* SEL 16-70mm f/4 ZA OSS (£800) and a Sony SEL Power Zoom 18-105mm f/4 G OSS (£500, and also destined to be matched to the next generation of NEX camcorders, with its friendly left hand operated PZ switch and quiet, controllable action). There may also be another power zoom, probably 16-50mm f/2.8 or a similar short wide aperture range, maybe even the 10-18mm in a power zoom housing. The reason these new lenses are made with constant apertures has nothing to do with the ‘Canon f/4 L’ obsession; it’s entirely to do with video work, to enable zooming without brightness change. The power zoom function is also there for video.

Caveat: the 18-105mm has a close focus of 45cm at 18mm, 95cm at 105mm. This indicates that the lens is not a true zoom but a varifocal. Varifocals are not of much use for zooming during a take in video, which goes against the constant aperture and power zoom features. So either the lens has an automatic compensation system which can refocus intelligently during power zoom, or a physical limiter on focus travel (unlikely – what would happen if you focused on 45cm at 18mm, then zoomed to 105mm?). The 16-70mm focuses to 35cm over its zoom range, and is actually capable of close-ups with better than double the image scale (less than a quarter of the frame enlarged) relative to the best the 18-105mm can offer, at 0.23X.

The relatively high level specification of the 16-70mm ZA does not necessarily indicate that there is a higher level of Alpha E-mount body on the way quite yet; at 20.1 megapixels (the same size sensor as the Alpha 58, with some improvements) the performance in terms of imaging may be optimal for a while. photokina 2014 should be when any professional body appears. But this is no way professional – it’s a mere £370 kit with 18-55mm f/3.5-5.6 E OSS, ISO range 100-16000, full HD video, A58-like viewfinder and general performance. You’ll see it in the shops before the end of September.

Sony’s agenda

Much has been made of Sony’s relationship with Olympus and the possible inclusion of OM-style 5-axis sensor stabilisation in E-mount bodies. Though the A3000 seems to have SteadyShot Inside (not confirmed by our man at the press conference, and not one of the features shown on the swingtags of the first cameras photographed by others) Carl Zeiss, traditionally wary of stabilised lens design, would not be issuing the 16-70mm with OSS unless fixed sensors were going to around in NEX and Alpha E-mount bodies for some time.

Whatever type of in-body stabilisation it has, the A3000 with SS looks like a good companion for existing un-stabilised lenses such as the Sigma 60mm, 30mm and 19mm f/2.8 designs or specialities like the Voigtlander Nokton 42.5mm f/0.95. However, I’m writing this prior to the big release of information this morning. Despite many statements that the camera does have IBIS, I see no rock-solid evidence that it does and I’m very aware that Sony staff if asked whether it has stabilisation could well say ‘yes’ on the basis of the OSS present in the kit 18-55mm lens. So, I treat this information with caution. It would not be the first time an expected feature has not materialised. Check the Sony site if you are reading soon after 5am GMT, I’ll amend this article later in the day.

Update 9am: full details are now widely on the web and there is no IBIS – here’s a complete rundown and sales page from B&H in New York on all the new products, including tech specs.

In the meantime, we know that Sony has been increasingly close to Sigma (a company which also works with Zeiss) and that some ideas may be shared between the two companies. One of the most important ideas promises to end the way your camera system choice locks you in to one company’s products. Sigma has taken the first visible step with its mount switching service. Future Sigma DSLR lenses can be returned to the workshop and their entire rear mount changed, at a cost, to another mount. So you will be able to own your 300-800mm (2014 version…) and if you switch from Canon to Nikon, the lens can switch with you. Now that many regular lenses cost £1000 or more and Sigma’s quality is so highly regarded (35mm f/1.4, MFT and E-mount lenses, DP series) it will make sense to keep the glass for longer. The new USB-interfaced lens calibration kit will also enable such lenses to be user tuned to work with their new host bodies.

The second idea is the switch to E-mount for more products by Sony. There is already a full frame E-mount Sony, the NEX VG-900E, and it’s actually a 24 megapixel still camera shooting raw, as well as a high-end full frame camcorder. It just gets very little attention because it does not look like an SLR or a NEX. This camera has adaptors for other systems of full-frame DSLR lens, as well as a specialised full-frame version of the Alpha mount plain adaptor (LA-EA3 without APS-C internal baffles found in the LA-EA1). However, third party makers have not yet gone the distance. Prime lenses from Samyang and Carl Zeiss are the main E-mount full frame offerings, made for video.

With the Alpha 3000 we see the introduction of an idea I sketched out for film cameras in the 1970s based on discovering the Contarex with its interchangeable 35mm backs. My concept was a camera body with a shutter unit, and a mechanical linkage for slot-in modules including a rangefinder mount, an SLR mirror-box with prism, and a pro mirror-box with interchangeable finders, plus several further front components to switch between Pentax, Minolta, Nikon, Canon and other lenses. Alpa came close to managing this with their very slim bodies and mount adaptors, plus a combination of optical direct finder and prism.

Sony’s future, like Sigma’s, lies in crossing all boundaries. The eventual full-frame, E-mount DSLR-style camera may well have the rumoured 36-50 megapixel sensor, 4K electronic viewfinder, and five-axis sensor stabilisation. It will also have an Alpha lens adaptor and firmware lens recognition good enough to let SSM and SAM in-lens focus motor lenses function adequately with on-sensor focusing. But what it will also have, for certain, is a range of adaptors for other mounts including Canon EF and Nikon G with translated control of AF and aperture (exactly what Sigma has now built in to the front ends of its ‘switchable mount’ new lens series). These will likely be third party products, but Sony has already shown (in 2010, at photokina and other shows) that it has no difficulty welcoming makers such as Metabones and Novoflex on board as co-operative vendors.

What’s more, in theory there will room to build a phase-detect mirror system (SLT) into some adaptors and even to add a focus drive motor. With the right chipset to translate the protocols from body to lenses, or to mechanical functions in the adaptor, almost any lens ever made for any SLR or rangefinder from the last century of miniature camera development will find a home on Alpha E-mount bodies.

Then you will have the ‘DSLR-CSC’ hybrid to end all – the body which can be sold with a Nikon mount, or a Canon mount, or an A-mount – or use its highly optimised future full-frame E-mount optics. To some degree the NEX has already done this but the real impact of the 18mm thick body, compatible with full frame lenses, has yet to be seen.

Caveat – if a full frame model does use sensor stabilisation, mechanical obstructions could mean that a crop factor of somewhere around 1.2X was needed. Sony already has pixel-shifting electronic stabilisation for video, not stills, and this also needs a crop factor to work. It would be easy to imagine the full-frame NEX accepting this limitation, and providing electronic stabilisation on-sensor only, removing moving parts and improving precision/calibration.

The NEX-5T

Sony-NEX5T-flipup

The NEX-5T has the same forward flippable rear screen mechanism as the 5R, one of the advanced over the earlier 5 and 5N designs.

The NEX-5T is the successor to the NEX-5R (5n, 5 etc), available as a black or white body. The 16.1 MP APS-C CMOS sensor NEX-5T will sell for around £600 and adds Near Field Connectivity technology to WiFi. Fifteen of Sony’s PlayMemories ‘apps’ are now available. Features include Hybrid AF (CD-PD on sensor), 180° tilting LCD, and maximum sensitivity of ISO 25600.

A divided path for Sony

Posted on By

Most Japanese camera companies have divisions, groups, and teams right down to the very last individual product. Even a single lens design may have its own small team, from R&D and design down to final assembly. What we are seeing happen in Sony right now is the result of complex competition and collaboration between several teams.

Take, for example, the new Sony 300mm f/2.8 G SSM II. You might assume this lens was mainly an Alpha division product from the former Minolta heritage, but in fact it’s been redesigned to work better with NEX and also with both consumer and professional HD video cameras from APS-C through Super-35 to full frame 35mm.

SLT/SLR system users gain with improvements like Nano AR coating (similar to new coatings introduced by Sigma, Nikon, Pentax and Canon), better MF control, and a better degree of weathersealing. It’s the complete update of the SSM motor (is it SSM II, or entire lens version II?) which provides compatibility with on-sensor PDAF and enhances CDAF, to offer the prospect of object-tracking AF during video. At £6,700 UK it needs to show major benefits to compete in the still field, but may have a market all to itself when fitted to the new NEX-VG900E full frame video camera.

It’s easy to think – ‘the first ever full frame video cam!’ but that is not the case. The Canon 5D MkII established the DSLR form as an acceptable professional video camera, and in the last three years a vast industry of shooting rigs, grips, follow focus devices, monitor screens and accessories has grown up all based on turning this video-unfriendly camera into something movie and TV crews are comfortable with.

Sony has implemented the sought-after 24 frames per second rate in all the new models just announced, not going for the European excuse of 25fps being close enough. This is to allow a so-called cinematic look, despite the fact that the movie industry has been trying to get away from 24fps just the same way as it threw off the shackles of 16 or 18fps many years before. Users want it, so they have at last provided it.

From the very start of reviewing HD capable cameras, we have emphasised the issues with audio – the *absolute* not optional need for audio fixed or adjustable manual gain control. I’ve done this for years in printed magazines. So has any other writer who ever had to use a camera with auto gain and nothing else. First Nikon (basic) then Canon (full control) and now Sony show they listened, if slowly and relunctantly, to something their own audio engineers would have told them was vital not a luxury.

End result – Sony enters the mainstream for HD video shooting with the Alpha and NEX systems.

The same technologies, in terms of sensor use and implementation of optical advances linked to Phase-Detection On Sensor (which I’ll call PDOS), now apply across the entire range of Sony digital imaging products from Handycam, through Cyber-Shot, through NEX, to Alpha. The Cyber-shot range is only missing an APS-C model.

What is particularly interesting is that this divided path is a parallel path now and not a divergent one. There’s no question of one straight and narrow path leading to heaven, one broad and easy road to hell, and winding ferny way to faery. Instead we get a four-lane highway joining Sony present to Sony future, with every option to change lane if you want to overtake.

Legacy and inheritance planning

Sony acquired a lot of old Minolta tech as a dowry in the 206 marriage to the Alpha system. Now having invested that legacy they have to make sure it still has value for future generations.

And example of what this really means can be found in the PDOS restrictions of the A99. The AF-D mode won’t work with some lenses, yet. For example – the 16mm f/2.8 fisheye, the 20mm f/2.8, the 16-35mm CZ f/2.8 zoom, any Konica Minolta zoom, any old Minolta AF system lens, the 35mm f/1.4, the 85mm f/1.4 CZ and G, the 135mm f/1.8 CZ and f/2.8 STF, the 200mm f/4 Apo G Macro, the 24-105mm D, any macro lens, the 400mm f/4.5, 600mm f/4, 200mm f/2.8 or the 300mm f/2.8 G SSM (pre-II). It is not even flagged as working with the 30mm f/2.8 SAM macro, 35mm f/1.8, 50mm f/1.8, 85mm f/1.8 or the 24mm f/2 Carl Zeiss SSM ZA. Or the 70-300mm G SSM, let alone the basic 75-300mm SAL.

It will only work with the 24-70mm f/2.8 CZ, the 28-75mm f/2.8 SAM, the 50mm f/1.4 current design, the 70-200mm f/2.8 SSM, the new 300mm f/2.8 G SSM II, 70-400mm f/4-5.6 G SSM and the new 500mm f/4 G SSM. Sony’s firmware requires that the user enter the focusing range involved. This is put forward as an advantage – making the system less likely to focus on a fence instead of the view through it – but in fact it’s an integral part of PDOS. Each of the 102 focus points spread across the sensor* is not a single pixel-pair, it’s a cluster of several pixel pairs tightly grouped. There may be the minimum of three differently pitched PDOS points per location, or perhaps more, to cope with the wide range of exit pupil conditions encountered when using Alpha-mount lenes.

For any one lens, the camera will need to know the broad focus range involved (hopefully the main PDAF array will normally provide this), the aperture at which focusing is taking place, and some further information about how the zoom or lens design influences the exit ray cone. From this, it will select the correct PDOS configuration and I think that for some lenses only a central zone will be active.

Sony states that firmware updates will add further lenses, but this technology only requires some relatively simple information based on the optical design. If they could have added more lenses from the start, they would have. Watch this space, because it may remain more of an empty space than you hope for.

* Sony imply that the PDOS area is large – actually it’s about 13mm square, within the APS-C zone, and does not extend towards the ends of the full frame much further than the cluster of regular PDAF points. These seem to be the same module as the A77, giving the A99 an AF ‘zone’ much smaller relative to its frame.

Zones and maps

The Alpha 99 also introduces something which almost has to happen if any of the above is going to work at all. Anti-aliasing filters do not have an even effect on sensors, especially full frame with wider angle lenses where the rear nodal point of the lens is relatively close. Geometry means that light passes through them at more of an angle towards the edges and corners, and there is therefore more distance between AA filter and sensor surface. With an AA filter having a single value diffraction-created diffusion of the image-forming light (aka blurring), the effect gets stronger as you move away from the centre (axis).

Since most lenses are also sharper in the centre and typical sensor microlenses are not ‘tuned’ from centre to edge, the overall result is to emphasise fall-off from centre to edge. Secondary results include a dramatic tendency for bright sources imaged in the extreme corners to have a strong, directional, surrounding glare. This is boosted by internal multiple reflection between the sensor surface and the inner face of the AA filter, especially if the incident rays are at 40° or less to the focal plane (where on-axis rays are described as being at 90°).

The best solution to this is the classic one – what Olympus called telecentric lens design, where you do your best to project the image on to the sensor from a relatively distant position keeping all rays, centre to edge, as close to 90° as possible. But that calls for new lens designs and also restricts the optical formulae, tending to produce much larger heavier lenses. It’s very practical on one-inch or smaller sensors, OK on MicroFourThirds, feasible for NEX but not much an option for a full-frame coverage.

So, Sony has introduced an AA filter which they describe as ‘multi-segment lo-pass’. It’s not one strength across the entire frame, but divided or graded to optimise performance towards the corners. At the same time, they have introduced a similar zoning to noise reduction, which we assume to mean the NR applies to the raw output before a raw file is saved. Combined with the usual sensor mapping, and lens profile based vignetting compensation, the overall effect of these refinements should be to:

  • Even out the apparent resolution and image acutance across the frame
  • Reduce the mapped peripheral gain effect, under which images appear to be noisier at the edges unless natural vignetting is allowed to be present
  • Remove artefacts such as corner streaking or softening, and fringes or flare from light sources towards the extremes

No doubt this is also combined with the detailed ‘repair’ function used to deal with PDOS. More on this later, as there’s an implication that the PDOS on the A99 is not the same as that on the NEX-5R or NEX-6, and may use a second layer of pixels leaving all 24.3 megapixels of the imaging layer untouched.

The area-specific NR is probably essential to achieve the high ISO range at 14-bit conversion, though it’s not unusual for cameras at this level which claim 14-bit conversion to have a variable true bit depth depending on ISO, image style and exposure conditions. We can assume that 14-bit will only be fully utilised under ideal conditions at ISO 100.

Exactly how Sony has managed to adjust AA values in ‘segments’ without visible transitions, we’ll have to find out. The same goes for NR.

The missing NEX-9

There is one camera absent from the September 12th launch – the 24 megapixel full frame NEX-9. The appearance of the HD video Handycam, NEX-VG900E, indicates that the model name for the full frame 24 megapixel NEX will be NEX-9. Images of the VG900 show it using an Alpha via the standard LA-EA2 adaptor, and we can be sure that this and not a special range of E-mount full frame lenses (almost pointless) will be how the NEX-9 takes A-mount glass.

In the meantime, the NEX-6 appears to be perfectly pitched in price, but see my comment below about GPS.

The missing GPS

While the A99 has GPS, we’re still left with no NEX model yet featuring GPS despite these being the ideal travel and walking companion. Nor is there a current SLT model with 16 megapixels and GPS, as the Alpha 55 replacement doesn’t have it and the ‘baby’ A77, the A65, is a 24 megapixel again. The Cyber-shot RX100 and RX1 models also don’t have GPS. Whether or not the new hot shoe will allow an add-on GPS remains to be seen.

The new 50mm f/1.4 SSM Carl Zeiss T* Planar

Whatever you think of Minolta glass, or new Sony glass, the Carl Zeiss name on a lens is a huge draw. Reactions to the otherwise rather pedestrian DSC-RX1 prove this. People will put up with being back in 1972 – the era of cameras like the Minolta Hi-Matics with fixed 40mm f/1.7 and similar Gauss design lenses of very high quality – if only it means getting rid of poor quality digital images. There was a time when you couldn’t sell a 50mm standard lens with a camera, and there was a time before that when every system was judged initially on the quality of its 50mm choices. We may be returning to that way of thinking.

Edit – at the 2006 launch of the Alpha 100, a 50mm f/1.4 CZ was briefly shown in Paul Genge’s presentation to UK/English language journalists. I did not report on this as none of the literature confirmed what we saw on the Powerpoint screen. I believe this lens has been planned for six years.

Flash

The new HVL-F60AM flash with rather weak video light and new hot shoe might seem an annoying departure, but remember, the A99 has no built-in flash and thus can not control wireless remotes without a commander. No HVL-F20AM style mini flash has been previewed, so the F60AM is the only commander. But your old flash will work fine off-camera controlled by your new one.

Parked on the hard shoulder

So, having looked at the four way road map for Sony, I must confess that I’m pulling into a rest area for a while. I did not sell my Alpha 900 or Alpha 77, and I’m glad I didn’t. Nor did I sell my 24mm f/2 even though it has been little used for a few months. It has been waiting for a 36 megapixel full-framer, which makes a 24mm a much better all-round lens because of the croppable image size.

I’m not one of those photographers obsessed by bokeh or the need to throw parts of my picture into extreme defocus. At 24 megapixels, APS-C is already seriously short of depth of field even at optimum apertures like f/9. I’m more likely to spend my money on a Samyang 24mm f/3.5 full frame tilt-shift lens to use with both the A900 and A77 than to invest in an A99. I have no use for a revised 300mm f/2.8, especially on full frame where it seems to me now to be a very conservative focal length, and though I’m sure a 50mm CZ will be wonderful I have no complaints about my Minolta-design Sony 50mm f/1.4. I do shoot video, but rarely in conditions which demand that I use full frame, and if Sony don’t put manual audio control into older models via a firmware fix, I’ll just buy a Canon 600D.

The price of the Alpha 99 is not as bad as people suggest, with UK stories launching it at £2082+VAT, or $3200. But I’ve got a very good quality pure still camera in the Alpha 900, with effectively noise-free imaging from ISO 100 to 320, excellent battery life and exactly the same maximum image size offered by the 99.

I think I’m in the market for the NEX-6 body but I do not care in the slightest about the WiFi aspect, or the downloadable apps. If the new remote control can actually trigger and end video shooting with the A77, NEX-5n (etc) I’ll definitely buy one. The RX1 is not for me either – had it been fitted with a 17mm, 20mm or even a conservative 24mm then it would have followed in the footsteps of the great wide-angle cameras I have worked with over the years from the Brooks Veriwide through the Plaubel 55W to Hasselblad SWC and Fujfilm G645SW. I would not even mind a separate optical finder for that, much; I was used to it!

Things we forget

The industry has put a huge effort into autofocus solutions ideal for interchangeable lenses and zooms, and apparently set aside the idea of external AF modules for good. With a fixed lens like the RX1, an AF module not working through the camera lens itself is a practical idea and could be far faster. We have also forgotten about those twin-lens compacts, with a switch to go from 35mm to 65mm (or whatever). Small sensor sizes, new lens design and ideas could make that concept work again.

The story of development for all types of camera is not over as there are old ideas to be revisited, and new ideas yet to come.

NEX-6 shown with 10-18mm f/4 OSS lens

Posted on By
The NEX-6 compact system camera from Sony puts DSLR power in your pocket
 

  • DSLR-quality images and Full HD video, from newly-developed large 16.1 effective megapixel Exmor APS HD CMOS sensor plus high sensitivity up to ISO 25600
  • New Fast Hybrid AF for optimal fast and precise autofocus in any situation; DSLR-like AF tracking for shooting at up to 10 fps
  • High-resolution XGA OLED Tru-Finder™
  • Intuitive DSLR-style operation with dual dials and Quick Navi interface
  • Download new features through built-in Wi-Fi with PlayMemories Camera Apps TM , the world’s first application download service*
  • Built-in flash and new Multi Interface Shoe

Editor’s note: no picture of the camera with the new 16-50mm collapsible lens shows the lens in any useful position, or from an informative angle, only head-on, as issued by Sony this morning. The image above shows the new 10-18mm wide angle zoom, a 15-27mm equivalent, with a constant f/4 aperture and the welcome inclusion of optical image stabilisation.

* For interchangeable-lens digital cameras as of August 2012

Step up to an imaging experience that’s in a class of its own. The new NEX-6 compact system camera from Sony packs the imaging power, shooting responses, handling and operability of a DSLR into a pocket-sized mirrorless camera.

Partnered with the growing range of E-mount interchangeable lenses, the NEX-6 appeals to committed DSLR users who need to travel light without compromising picture quality. Offering big-sensor picture performance in a compact body, the new camera also makes an ideal option for step-up photographers looking to significantly expand their creative options.

The NEX-6 shares many imaging innovations with the newly-announced NEX-5R – from a responsive Fast Hybrid AF system to Wi-Fi connectivity and downloadable Camera Apps.

Crafted with discerning photographers in mind, the new camera also features the same precision electronic viewfinder and DSLR-style ergonomics found on the flagship NEX-7.

The large Exmor APS HD CMOS sensor inside the NEX-6 offers 16.1 effective megapixels for true DSLR-quality images and detail-packed Full HD video. It’s teamed with the powerful BIONZ image processor that ensures flawless, low-noise images – even when you’re shooting dimly-lit interiors at extended sensitivity settings up to ISO 25600.

Similar to the recently-announced NEX-5R, the NEX-6 features an innovative new Fast Hybrid AF system that combines phase- and contrast-detection autofocus methods to suit virtually any shooting situation. Phase-detection AF that quickly analyses subject distance is complemented by contrast-detection AF to confirm extremely fine focus. In Speed Priority mode, the NEX-5R switches automatically to pure phase-detection tracking AF. You’ll enjoy DSLR-like focusing responses when you’re capturing fast-moving action with high-speed burst shooting at up to 10 frames per second.

From launch, Fast Hybrid AF is supported with these lenses: E 18-55mm F3.5-5.6 OSS; E 55-210mm F4.5-6.3 OSS; E 18-200mm F3.5-6.3 OSS; E 24mm F1.8 ZA Sonnar T*; E PZ 16-50mm F3.5-5.6 OSS. Firmware upgrades will steadily expand the range of lenses offering Fast Hybrid AF support.

As with the NEX-7, the NEX-6 features an XGA OLED Tru-Finder™ for precision framing and focusing. This acclaimed electronic viewfinder gives a bright, detail-packed, high contrast view of still images and video, with 100% frame coverage and a wide field of view to rival pro-grade optical viewfinders. On-screen grid lines and a digital level gauge can be displayed to assist with accurate framing.

The OLED Tru-Finder™ is complemented by a 7.5 cm (3.0″) Xtra Fine LCD that can be angled up to 90° up or 45° down (approx.) for easy viewing in virtually any shooting position. The LCD screen assures superb detail and contrast with significantly reduced on-screen reflections, aiding composition when you’re shooting outdoors or in direct light.

Despite its compact body dimensions, the NEX-6 offers instantly reassuring operation for DSLR enthusiasts. A strategically-positioned mode dial on top of the camera allows quick setting of shooting modes – including P/A/S/M and Sweep Panorama – just as you’d expect on much larger interchangeable lens cameras. It’s joined by a control dial located under the mode dial, plus a separate control wheel on the camera back for fine adjustments of exposure, ISO, white balance and other settings.

Also inherited from high-end A-mount cameras by Sony, the pro-focused Quick Navi interface allows fingertip adjustment of settings without taking the viewfinder away from your eye.

Full HD movie shooting is enhanced with a new Auto Slow Shutter feature that adds extra sparkle to low-light clips. The NEX-6 detects dim interiors and night scenes, automatically switching to a slower shutter speed to brighten up your footage.

Shared with the NEX-5R, integrated Wi-Fi allows simple wireless photo and video transfers to various smartphones or tablets running the free PlayMemories Mobile app. Images can also be transferred wirelessly to a networked PC, or viewed wirelessly on any DLNA-compatible TV.

As also featured on the NEX-5R, PlayMemories Camera Apps expands the capabilities of the NEX-6 as your shooting needs evolve. Just connect the camera to your PC via Wi-Fi or USB. Then log in to your Sony Entertainment Network (SEN) account and explore the world’s first download service1 that lets you install new functions on demand. From launch, available apps include Picture Effect+; Bracket Pro; Multi-Frame NR; Smart Remote Control and Direct Upload. Sony also plans to introduce further apps such as Photo Retouch, followed by Time-Lapse and Cinematic Photo.

Alongside a handy pop-up flash, there’s a versatile new Multi Interface Shoe that’s capable of ‘intelligent’ linkage with various accessories.

New interchangeable lenses for E-mount cameras

The choice of interchangeable lenses for E-mount cameras by Sony grows with three additional models.

The SELP1650 is an extremely light, compact 16-50mm F3.5-5.6 powered zoom lens with Optical SteadyShot image stabilisation built-in for clearer handheld images. The lens body measures just 29.9mm when fully retracted, making the SELP1650 an ideal travel companion. There’s also a dual-function ring that controls both power zoom and manual focus, depending on operating mode. With the camera set to AF the control ring adjusts smooth, high-speed zoom with small hand movements. With the camera in MF mode, the ring controls manual focus. Smooth power zoom makes the lens particularly suitable for video shooting.

The SEL35F18 is a fast 35mm prime / fixed focal length lens with a bright maximum aperture of F1.8 and Optical SteadyShot built in. It offers excellent optical sharpness and clarity as well as bokeh effect– whether you’re shooting portraits, street scenes or Full HD video. Featuring a new exterior design, the lens is easy to handle and light to carry.

Adopting the super ED (Extra-low Dispersion) glass which reduces colour aberration, the SEL1018 is a super-wide angle zoom with a maximum aperture of F4 right across its 10-18mm range and Optical SteadyShot image stabilisation inside. Ideal for landscapes and interiors, it’s also capable of producing dramatic perspective effects at its widest setting.

New accessories for NEX-6

Crafted in genuine leather, the LCS-ELC6 Soft Carrying Case combines a stylish body case and lens jacket. Styled exclusively for the NEX-6, it’s suitable for use with the camera and attached SELP1650 or SEL16F28 lens. The camera’s LCD screen can be tilted even when body case is attached; tripod attachment is also possible with the case attached.

The LCS-EJA Soft Carrying Case can be used for all α E-mount cameras, and is ideal for use with the new SELP1650 or SEL16F28 lens attached. Internal pockets offer space to store the front lens cap and a spare memory card.

For further details of the full range of lenses and accessories, please visit: www.sony.co.uk/hub/nex-compact-camera-system/accessories

The new NEX-6 compact system camera with interchangeable lenses is available in the UK from mid-November 2012.

What the buyer wants – NEX-F3, Alpha 37 and more

Posted on By

SONY is sometimes accused of not listening to the Alpha or NEX owner when it comes to what features they include in new cameras, and what modifications they offer through firmware to existing owners. There are two points of view on firmware; some criticise updates, saying the product should have been released with the right stuff inside on Day 1 while other praise those makers who issue frequent and valuable firmware revisions because they ‘supporting the product’.

My view is the latter; if I own a camera, I really don’t care much what bells and whistles are added to its successor in hardware as I know the only way to get those is to buy the new model. But I do value firmware updates and I know that far more could be done to keep the firmware of older models in top condition. I guess they would have to issue a new camera manual and don’t want to improve the user interface or add functions not included in the original!

Sony does listen, but it listens harder to new potential buyers than to existing owners. It listens to the untapped market, to the people who buy someone else’s camera instead of Sony. After all, it’s already got the existing owners. It only needs to listen to them as far as the next camera upgrade goes for the proportion who will be likely to change frequently.

The new NEX-F3 is a perfect instance of listen to the unconverted market. They want an LCD which aims forward so they can film themselves; amateurs only get one take for their home porn movies and can be very disappointed to find they’ve cut the important bits off. I am, of course, talking about guitar porn, cookery porn, motorcycle porn and not the other kind…so Sony has made the LCD flip over the top.

They have in addition made this entry-level NEX 3 model use the latest 16.1 megapixel sensor, generally agreed to be the most versatile all-round sensor on the market, and accept the accessory FDA-EV1S EVF which doubles Sony profits on any camera sold, should be buyer decide later they want an eye-level electronic finder. The battery life has been extended by 18% to 470 shots per charge, and if you buy the higher capacity 1300mAh Japanese made third party cells in place of the Sony 1080mAh ones which cost six times as much, you win twice. Except that I’ll bet the NEX-F3 adds another layer of battery compatibility protection, just like the 5N and 7 did. The third party cell makers had to update their stuff fast and warn buyers that they needed a compatible type, people owning older clone cells found they didn’t work in the new cameras.

Since this camera is the first NEX (or any Sony Alpha/NEX) to offer in-camera USB connection recharging, the odds are not just high that clone cells won’t work. It’s what bookies call a dead cert. Being able to use your iPhone charger (just a different cable) or similar USB mains-plug or in-car 5v adaptor cuts down on all the rubbish we have to carry when travelling.

To keep the distinction between entry level 3 and better 5 to 7 models clear, Sony has restrained the video to 50/60i with final 25p (European) or 24p (US) output. The better models offer full 50/60p as their top quality. But Clear Image Zoom is included, which does a pretty good job for the everyday user of providing a 2X electronic converter with acceptable full resolution sharpness. There’s no microphone input and some new software which sounds horrible is bundled – PlayMemories Home. Sony, just because you got to use words like Play, Walk, Memories, Man, Stick, Station and so on in various products does not mean they have to be repeated in child-like product names for all eternity!

Sony has added the pop-up flash from the NEX-7 to the F3. Is this a good idea? I predict some deeply disappointed flashers.

It rises just so high above the camera, and it’s not absolutely identical to the 7; the position appears comparable. The new F3 will be sold with the usual single or twin kit lenses I’m sure, and not so often with the latest 18-200mm LE (lite version E?) zoom which has been launched at the same time. This lens is a direct counterpart to the Tamron 18-200mm VC III f/3.5-6.3 which I’ve been used since early March. Though Sony has stated that the OSS (VC) is not as efficient as the more expensive Sony SEL 18-200mm, my findings using the Tamron are that it’s modified to be very smooth during video as has the AF action, which is less volatile than other SEL lenses.

Now I’m sure this lens will be very popular – the Tamron version is sharp and quite beautifully finished, with Sony’s rubberette dust attractor grip absent and a slick metal barrel skin with broad easily cleaned rubber ribs doing the zoom and focus work instead. Tamron’s £499 lens looks like £699 where Sony’s £699 will look like £299 after you have handled it with bare skin for a few minutes. Sony should issue silk gloves with all their lenses.

But here is the downside of choosing such a lens as your kit zoom for the NEX-7 and presumably for the F3. The pop-up flash just doesn’t clear the lens well enough and to use flash with the 18-200mm you must buy the accessory FVL-F20S flash which lifts the light source high enough the camera to avoid what you witness below.

You may also be unimpressed by the uncorrected complex barrel distortion of the 18-200mm Tamron at close range, demonstrated here by photographing an A2 printout of an Adobe lens correction target. Actually, the Tamron profile included in the latest Adobe Camera Raw does a nearly perfect job of straightening up this lens at average scenic distances. This profile should also work with the new Sony lens. What’s good about the Tamron is that its lens identity is recognised by ACR and the correct profile auto-selected.

What you are looking at above is the shadow of the lens, at 18mm, with the lens hood removed and the NEX-7 internal flash used. It is possible the NEX-F3 will be a very small amount better than this.

Here is what happens if you carelessly leave the lens hood on! An A2 target is much the same size as a two-face close-up wide angle portrait, or a typical pet shot or party shot; times you use flash. The shadow does not get smaller further away, but you can dispose of it by using focal lengths over 150mm. Wow!

In other words, Sony has listened to what the public wants – pop-up flash and a superzoom they can afford – but in such a compact body, with no pentaprism-shaped top to allow a good ‘lift’ when the flash is popped up the result will be more than a few unhappy beginners. That is some shadow by any standards.

The Alpha 37

And so to the second consumer-focused launch by Sony this month, the also-16-megapixel Alpha 37. You can think of it technically as a NEX-F3 in an Alpha SLT format – same ISO 16000 top but with 100 at the bottom thanks to the SLT pellicle mirror, same 5.5fps regular motordrive, similar 450/500 shots per battery charge depending on whether you use the power hungry EVF or the economical rear LCD.

You can see here how much extra height the GN10 pop-up flash gains compared to the GN6 of the F3 or NEX-7. It should clear many lenses even with hoods attached, and may well prove usable combined with the new SAM lens for the Alpha range – a slightly more compact 18-135mm f/3.5-5.6 using a type of SAM motor which is claimed to be silent and which allows DMF. Remember that earlier SAM designs with the audible motor have not allowed DMF and have even been quite picky about exactly how you set MF instead of AF. The presence of DMF in the new lens indicates that the SAM internal motor focusing may be a lot closer to SSM than to some basic flavours of SAM. I like the idea of this lens, 18-135mms can be surprisingly good though the f/5.6 long end maximum may actually be slower than many 18-200mm or 18-250mms when set to 135mm (they tend to be f/5 at that point).

Is it a Tamron? Probably not. Tamron lens locks move forward to lock the zoom action. Sigma lens locks, though traditionally placed on the left side, move back towards the camera to lock the lens. Sigma has flavours of HSM which allow DMF and others, like the HSM on their 18-250mm OS, which don’t. I look forward to reports on exactly how the 18-135mm works and whether its superior SAM makes it a hidden bargain.

And also, of course, whether the pop-up flash casts interesting shadows!

There is not a lot more to say about the A37 except that it shares most limitations imposed on the F3 such as the video format and bitrates, that it has the usual bells and whistles including an auto portrait crop framing mode, and resembles an A55 body size updated to be more ergonomic. It also has an updated A55 type EVF, not to be confused with the OLED Tru-Finder of the NEX-7, A77 and A65 but identical to the A57. There is a spectacle friendly EVF mode, which as far as I can tell reduces the image area to match the A55 (which wastes loads of its screen as a blank surround). The big improvement made by the A57 was to deploy the full area of the 1440k-dot screen instead of using it as a milky luminescent border for a small image. The downside is that spectacle wearers find the full area hard to see edge to edge.

The rear screen is 2.7″ not 3″, since this is a very compact body, and uses the double hinged up/down tilt mechanism without rotation or forward facing options.

I did not expect to see GPS in this model, but after several expeditions with the Alpha 77 I am beginning to doubt whether onboard GPS as provided by Sony is much help at all. There have been far too many entire shoots where not a single frame has GPS data. It is something I find extremely useful but it’s only useful if it works most of the time. It’s odd to see USB charging introduced in the F3 but not present in this model. Lack of communication between product teams?

The pricing of the A37 will be very competitive indeed.

With all these various May launches – NEX-F3, 18-200mm LE, Alpha 37, 18-135mm SAM – there’s clear evidence that Sony listens first to mass market dealers and to potential new adopters of large sensor interchangeable lens cameras, those moving up from compacts. Everyone who has ever passed an Alpha or NEX fitted with an 18-55mm lens to a compact zoom user will know the reaction – that the zoom doesn’t even begin to zoom, by their standards. They can’t believe you can not frame a face from twenty feet away.

All Sony’s advances are geared to making these larger format cameras more satisfying to the upgrading user.

Now we just wait for them to produce 2012’s models designed to keep the upgrading Alpha and NEX user equally happy.

The truth about 24 megapixels

Posted on By

There is a rumour, which the ides of August may stab in the back or elevate to divine truth, that the coming Alpha 77 will have 24 megapixels.

Because of this rumour, there is a lot of very negative discussion going round to the effect that 24MP on APS-C is far too much and the results will be poor (etc).

Well, they may be, if you think Canon’s results are poor – you can judge that for yourself, try a Canon. But they do not have 24MP sensors!

They also do not have APS-C sensors, in the same way that Sony does. They have smaller APS-C sensors with lots of pixels cut off all round the edges. Sony has chunky big APS-C sensors with acres of extra pixels to spare. This is a slight exaggeration of the situation, but hey, I may as well join in the mood of unrestrained opinion!

Facts: Canon’s 18-megapixel sensor makes images 3456 x 5184 pixels in size (give or take a few, depending on your raw processor). Fact: their smaller 1.6X factor sensor measures 22.3 x 14.9mm. Fact: Canon states it is approximately a 19 megapixel sensor with 18 megapixel final output.

Facts: Sony’s 16.2 megapixel sensor measures 23.5 x 15.6mm and into this packs 3264 x 4912 pixels (active area).

If you made a current Canon pixel-pitch sensor the same 1.5X size as a Sony sensor, it would be around 19.7 megapixels active from a 21 megapixel total. If you put Canon pixels on an existing Sony 1.5X sensor, you would be up to 3618 x 5463 pixels and 24 megapixels needs to be 4000 x 6000.

Clearly it’s not the quantum leap some people think, just a quantum leapfrog over Canon’s back with the benefit of the larger sensor. And it’s worth considering that APS-C covers sensor sizes up to a true 24 x 16mm, for Super-35 video use, and that such sensors have already been made. A few wide-angle lenses and zooms might be a bit tight on the image circle, but that half millimetre one way, 0.4mm the other way, adds up to a surprising number of pixels, enough to take the 19.7 megapixels up to 20.7 megapixels without changing from Canon’s current pixel pitch.

So don’t panic. The chances are that 24 megapixels on proper, big Sony APS-C will perform very well. If you’ve got the glass and the technique to make it…

Worldwide demand delays Alpha 560 launch

Posted on By

According to Don Long writing for the Photo Marketing Association Newsline, Sony San Diego claims that the reason for the delay in the Alpha 560 rollout is worldwide demand, stretching the capacity of the Sony factories to the limit.
See:
PMA Story
Remember, right at the start when Sony took over from Konica Minolta, Photoworld and Photoclubalpha reported the new staff as saying that Sony did not expect to sell two, or even threee times, the Minolta historic figures. They would sell ten times the quantity that Minolta had ever sold. It seems the view expressed by UK Sony executives in 2006 was realistic; Sony is an entirely different scale of operation.
But maybe they still have some of the same facilities that Konica Minolta bequeathed to them, and maybe those are simply not capable of turning out certain types of camera body in the required quantity fast enough.
The Alpha 33 and 55 have been given priority and only the 16-megapixel Alpha 580 will appear this year. What chance, at photokina, of an Alpha 700 successor to match the Nikon D7000 now announced with its 6fps 16 megapixel sensor and HD movie capability?
Olympus has now scotched rumours they were pulling out of the DSLR market with the E-5, a FourThirds successor skipping the unlucky number E-4 – but unless the performance pulls something out of the hat way beyond the specifications (12.3 megapixel and 720p HD movie, basically a 2008 spec) they might as well have dropped the ball.
And Samsung, with the NX100, has rather neatly chosen to show Sony what the NEX could have been. They have had the clever idea that since the focusing ring only instructs the camera to operate the focus motor, it can equally well be told to control the aperture instead when a button on the body is pressed. This simple i-Lens function restores in one step an almost instinctive photographic left-hand action we have almost forgotten.
It proves that there are engineers out there over 40 years old, too…

Four new Alphas – and two 'translucent'

Posted on By

It’s a funny word to use, because the mirrors involved are transparent and not translucent (which implies passing light but not in an image-forming manner). Translucent means semi-opaque, letting light through in the way that an opal perspex sheet or Kodatrace foil does. Transparent means something you can see through.
But now, thanks to the wonder of changing language, translucent is also going to have to mean transparent, or semi-transparent. Pellicle, semi-silvered, whatever term you wish to use.

Unfortunately, for this writer the misuse of the word translucent stands as one of the biggest schoolboy howlers ever imposed on the entire world by the ignorance of a corporation. It’s such a glaring error I can hardly bring myself to use the term – others, like Dave Etchells, have happily assimilated the new meaning into their technical lexicon. And as the video above shows, they’ve made it into a trademark, a permanent part of the future of this technology.
Wiki, and pretty well every dictionary ever published, disagree with Sony’s imaginative use of a word from which they have now removed its exact meaning:
Wikipedia: “Transparent materials are clear, while translucent ones cannot be seen through clearly.”
Merriam-Webster:

trans·lu·cent/transˈlo͞osnt/

Adjective: (of a substance) Allowing light, but not detailed images, to pass through; semitransparent.
(the semi bit of semitransparent cited here seems to mean semi-detailed, vaguely delineated – not slightly darker; otherwise the primary definition of the word is diluted).
There has been some heated argument on dPreview forums about this post of mine (my view is shared by many). No-one has made the point that words evolve to have useful exact meanings. Transparent and translucent are words which may once have shared a common poetic meaning in 18th century descriptive writing, but whose meanings were refined with the progress of science and technology. This process in the course of over 200 years resulted in a useful distinction between the meanings of transparent and translucent. Sony’s commercial misuse of the word Translucent is damaging to the English language and to the scientific and technical lexicon; it predisposes future confusion about the meaning of the words.
It is also a fait accompli; there is no turning back, since Sony’s corporate stance is much like that of Mrs Thatcher; no u-turns and never admit to be being wrong. They have also no doubt invested hundreds of thousands of dollars in the consultancy involved, and the registration of the term as a trademark, the creation of branding artwork.
They could have branded the mirror TransLumina® or, more usefully, just called it a transflecting mirror – transmitting-reflecting. That term is already used to describe the sort of mirrors used in ‘Big Brother’ with cameras behind them.



As to whether it’s a true pellicle mirror (a thin stretched film of vacuum coated Mylar or a similar polymer) no-one seems to be clear. It moves out of the way to allow sensor cleaning but could be relatively fragile. It certainly does not need to move to allow 10fps (Alpha 55) or 7fps (Alpha 33) continuous shooting. Sensor dust is often created within the camera by wear and tear on the shutter mechanism, so access for cleaning is essential and the mirror can not be designed to seal the sensor chamber. The Alpha models still have a shutter, that’s the next thing we shall see eliminated. That old rumour of the 15fps silent shooting Alpha DSLR seems to be more than a rumour; we are almost there.


For many users, the critical advantage of all four new Sony models will be HD Video with sensor-based in body image stabilisation. This will enable all kinds of lenses from macro to ultrawide or soft focus, manual adaptations and Minolta AF legacy glass to be used for video with confidence.
Welcome back the circular polariser, unlike mirrorless ILC cameras these new models will not allow the use of linear polarisers without AF efficiency reductions, but exposure should be unaffected as the sensor itself provides the metering with 1200 zones.
This will be one of the tests reviewers need to carry out on the new pellicle mirror Sony Alpha 33 and 55 models – to confront them with not only polarising filters, but conditions in which light is naturally polarised. How will they render sky gradations or reflections off water?
Two further Alpha models are being released, which are essentially updates for the 500/550 – the Alpha 580 which will hit the shops before the winter buying season, adding 16.2 megapixels and a 15-zone AF module, HD 1080p video and (non-video) Contrast Detect AF with all Alpha mount lenses. The 560 will not arrive until some time in 2011, using a 14.2 megapixel sensor.
Versatile features
More of a landmark than a benchmark, the inclusion of 10fps continuous shooting with active phase detect AF and 16.2 megapixel file size in the Alpha 55 is unprecedented and possibly unforeseen by competitors, in this class of sub-$1000 consumer DSLR (let’s continue to use the term, since they are clothed as DSLRs). The dual format card drive supports the 30Mb/s transfer rate of the latest Class 10 SDHC cards and Sony’s fastest MemoryStick Pro Duo generation. The HD video also has a reasonable 17mbps  bitrate.
The new technology has been well documented before the launch, but the fine detail of the new cameras is now clearer. The Alpha 55 is some markets will incorporate GPS geo-tagging for stills and videos (we wait to see whether raw files are tagged, and how accurate this is – the accessory Sony geo-tagging system available to date has only permitted JPEG tagging, and has not been accurate enough to know which street in a town the picture was taken in).

Rumours that the 33 and 55 bodies would be SSM/SAM only, with no internal focus drive, were unfounded as Sony states clearly that both are compatible with ‘the full range’ of over 30 Alpha lenses (indeed, the product shots of the 33 and 55 alone show the 18-200mm SAL DT lens fitted). The 55/33 1080i/60p (1080p in AVCHD camera archive format) video claims ‘smooth, precise’ phase detect auto focus during video shooting, but makes no reference to this being limited to in-lens motor lenses. Therefore we can assume it works with in-body AF drive lenses as well, and you just have to edit the soundtrack.
The new ISO 25,600 mode does not imply a radical sensor change as it is only available using Multi-Shot Noise Reduction, which requires a burst of 6 frames at the 10fps/7fps native maximum speed of the camera, and can not save raw files. The ISO range of the sensors is 100 to 12,800. Is this range quoted as absolute, or after accounting for the semi-silvered mirror light losses? If it’s the range before allowing for the mirror, then the 14.2 megapixel sensor of the Alpha 33 may be more like the Nikon 3100’s sensor than the NEX (ISO 200-12,800) is.
Thom Hogan has shown pixel dimensions and size data which support Nikon’s claim to have an entirely different sensor fab line of their own, compared to the A550/NEX sensor. But how about compared to the A33/560 sensor?
The 55’s new 16.2 megapixel CMOS will probably appear in the forthcoming Alpha 700 successor, which it is believed will form the main Sony exhibit at photokina (Cologne, September 21st-27th). Both models have a new 15-zone AF sensor with three cross sensors, but not f/2.8 sensors – all are designed to operate at f/5.6 virtual aperture. However, there is a hidden clue that the cross sensors may be f/3.5 capable, as the high-speed shooting modes with continuous AF set f/3.5 by default on any lens capable of this (if the lens is, say, only f/5.6 then the largest aperture is always set). Setting f/3.5 implies that this confers an advantage in focus sensitivity over f/5.6, f/4 or any other particular aperture – and that f/3.2, f/2.8 or wider would bring no benefit. That points to some of the sensors having an f/3.5 virtual aperture.
The new cameras are known as SLTs – Single Lens Translucent – instead of SLR. See my intro. Did they have no English speaking staff on their team? I’m sure there is a German word which describes their mirror correctly. I’d rather have the right German word than the wrong English one. Ah well, as the bloke leaning on the pub bar says, durchsprung vor technik…
Confusing aspects – Auto HDR is said to be available in P/A/S/M modes. I guess in M mode it must leave the aperture alone and change just the shutter speed. Regular bracketing is still limited to a disappointing 3 exposures at 0.7 EV intervals, maximum.
But you’ll love the direct D-Range button which gives access to D-Range and HDR options directly, and the direct Finder/Screen button which toggles between using the very high resolution EVF with its ‘virtual 1.1X’ 100% view of the subject – effective visual scale, larger than the Alpha 700 and larger than any previous Alpha digital model except the Alpha 900 and 850. That’s one of the benefits of the EVF, a relatively tiny display is viewed through a high magnification ocular and ends up with a ‘window’ on the world which beats the tiny tunnel vision of optical finders. Technically it is very similar to the last EVF produced by Konica Minolta on the Dimage A200, with the benefit of five years’ further development. It has the same 60Hz refresh rate and visually almost raster-free RGB.


Where the A550 and its earlier stablemates vary slightly around a viewfinder with an effective 0.50X scale (relative to a full frame 100% view using a 50mm lens), the A55 and A33 provide an effective 0.73X and that’s impressive. The ocular is set well back (remember the Konica Minolta A2, and the Sony Cybershot DSC R-1?) because it is a telescope design. This also gives it a very narrow range of possible eye positions, a common feature of EVFs. The eyepoint is close, and you must position your eye precisely.
The rear screen uses the same type of (Schott?) reinforced glass with (3M?) resin gel adhesive as Canon’s 7D – this totally seals to the LCD module itself eliminating air gaps, and improves contrast. It is a technology first seen in the 7D and becoming standard across the industry though the NEX has shown Sony to have the best implementation so far. It is scratch proof, by the way, and it can be cracked by impact like any other screen.
The tilt-swivel action is borrowed directly from the Nikon D5000. In fact, it’s so identical in articulation it even included the amazingly silly front facing mode where the screen is obscured by your tripod, hanging under the camera and preventing it from being placed on a flat surface for self-portraits or videos. But it has the same benefit as the Nikon, the screen can be flipped to face the camera and protected completely while you use the EVF.
Functions familiar from the NEX including Sweep Panorama and Sweep 3D Panorama are built-in and accessed from the main mode dial, which also provides physical settings for all the main modes. Depth of field preview is restored – with the usual button – because is can now actually work. It was always useless in real terms on optical viewfinder cameras, as the focusing screen never represented wide apertures correctly.
Now, with an EVF, for the first time ever an eye-level Alpha gives absolutely perfect and precise previewing of depth of field and bokeh effects whatever aperture you are working at – even at f/1.4, which was never possible and still isn’t with the A850 or A900 for that matter (which is why their Preview mode is useful).
You can also preview the exact image appearance. By pressing the AE lock button, the auto gain of the EVF or rear screen are turned off and replaced by an exposure-compensated view. So if you dial in -1 EV (using the adjacent dedicated button), and change the WB, and use a different picture style with more saturation and contrast just pressing AE-Lock will immediately preview your image with these adjustments applied. And you can enlarge in the usual two steps to check auto or manual focus.
The finder and screen also have a Nikon-style two axis spirit level (flight simulator horizon) display to help you get your horizontals straight and your verticals parallel. It can be activated on either, and does not have to appear on both simultaneously.
For movie makers, the binaural stereo microphones are a great move. Even on the NEX, the two small top aperture mics give excellent stereo. The 33/55 mics are placed either side of the ‘prism’ housing, rather like the ears on your head. This will give the stereo image created by these cameras a really natural quality. Natural, that is, to a pygmy marmoset monkey… but still, I will wager, the best stereo image of any DSLR/HybriD. And Sony provide a stereo 3.5mm mic jack socket, though without any manual control of gain levels.

I’m sure we will have to buy the A780 to get that. Click the picture above for a big version. Who says Sony does not have a range to match Nikon or Canon, whether or lenses or of cameras? From the left, the cameras show the current range before we even see the magnesium-bodied Alpha 700 replacement arrive. A900, A850, A580, A560, A55, A33, A390, A290.

New Alpha 290 and 390

Posted on By

Sony has announced two new cameras this morning – but it’s not an announcement which will have Alpha system users rushing to the cashpoint and queuing at Sony Style. The Alpha 290 and 390 are dumbed-down versions of the 230/380 with user interfaces partly borrowed from the NEX including the built-in Help Guide. The rear 2.7 inch Clear Photo LCD screeen does most of the work of communicating with the user.
