Sony collapsible pancake zoom specs

Posted on By

The Sony NEX system collapsible zoom will be an f/3.5-5.6 design focusing to 0.3m if specifications accidentally included with the information on the NEX-5R are accurate. And it will be a power zoom, we think.

The Sony.com info includes in the camera specification this line:

“AF Illuminator : Built-in, LED type (with a range of approx. 0.3-3.0m (with E PZ16-50mm F3.5-5.6 OSS attached))”

This is not the existing 18-55mm OSS lens shown on the camera product shots, or included in the list of compatible lenses. The clue is in the name, E PZ instead of just E or SEL. The 50mm could easily be a typo, but combined with the different focus range (down to 30cm instead of the 25cm minimum) we think this reference is definitely to a new compact, collapsing 16-50mm f/3.5-5.6 power zoom.

Those who are hoping for an f/2.8 might indeed get one of a different type,  but this specification looks competitive as a replacement for the 18-55mm, and not unlike the Olympus/Panasonic Micro FourThirds 14-42mm collapsible power zooms.

All the stocks of the NEX-5R currently being offered, and all the samples apparently previewed by the press, have been fitted with the old (existing) 18-55mm OSS lens.

Here is the page on which you will find, under the specs for the AF illuminator only, the reference to the previously unannounced E PZ lens model:

http://store.sony.com/webapp/wcs/stores/servlet/ProductDisplay?catalogId=10551&storeId=10151&langId=-1&productId=8198552921666484205#specifications

Here is a page listing all the current compatible lenses (expand to view 10):

http://store.sony.com/webapp/wcs/stores/servlet/ProductDisplay?catalogId=10551&storeId=10151&langId=-1&productId=8198552921666484205#compatability

It is worth noting that the Phase Detect PDAF system of the NEX-5R could reduce the true resolution of the central focus zone by as much as 20% locally (vertical) and raw image interpolation will restore the integrity of the images despite 99 focus points, each one of which uses three different sensel-based phase detect pixel pairs to cope with the range of exit pupil positions found on different lenses. Since the outer zone of any image is usually slightly lower resolution than the centre, the effect will be to make the NEX-5R more even in sharpness/resolution across the frame but lacking the very sharp centre zone normally found.

Added: we calculate that the PDAF uses 594 single pixels at the minimum based on three pixel pairs (one for each of three exit pupil positions) per AF point.

Effective PDAF depends on the camera knowing the actual design of the lens, because the focus distance and the rear exit pupil (rear nodal point and exit pupil diameter) are both needed for the camera to switch seamlessly to the correct pitch of on-sensor PDAF points. On-sensor PDAF is a bit like the old microprism or split image screens, it depends on a relative darkening of one side or the other of a pair of pixels as focus is changed. It works best close to the lens axis and over a specific range of apertures.

New lenses can be designed to be highly efficient with on-sensor PDAF. On-sensor PDAF has probably been designed to be usable with older lenses. What you probably can not expect from the 5R, or other on-sensor PDAF models, is reliable PDAF using SSM or SAM Alpha lenses on an LA-EA1 adaptor. It may be that it won’t work at all with some Alpha lenses even if they function with contrast detect focusing (and will still use that on the 5R).

ACR 7.2 and Lightroom 4.2 RC – RX100 compatible

Posted on By

The good news is that you can now download, free, the Release Candidate versions (expire October 31st) of Adobe’s Lightroom 4.2 and Camera Raw 7.2, as well as DNG Converter 7.2, which will give you raw conversions for the Sony Cyber-shot DSC RX-100.

The bad news is that no camera lens profile is included, and until someone creates one, the distortions and CA of the RX-100 lens are not corrected by these programs. Also, we can confirm that no further highlight recovery is possible, beyond that already enabled in Sony Image Data Converter. This has not always been the case with ACR/LR. They have often enabled clipped highlights to be recovered with useful detail from KM and Sony raw files. The RX-100 raw files are right on the edge of overexposure and you just can’t pull burned out highlights back in.

But against this, the high ISO performance of the RX-100 is superior to, for example, the NEX-5n. That’s surprising and worrying, as the 5n is better than the NEX-7. ISO 3200 images from the RX-100, processed through ACR 7.2RC, are about as good as any APS-C camera currently manages and not far off what can be expected from a full framer.

Shot at f/1.8 on the RX-100, 1/30th, ISO 3200 – about as dark as it gets for hand held shots.

100% ACR 7.2 clip with NO noise reduction at all and no sharpening

On the Canon 5D MkIII, 1/3oth at f/2.8 using the 40mm pancake lens – twice as much light as the pub scene above, gold Olympic letterbox in Edinburgh seen by night time street lighting

Sure, at 100% under the same process conditions it is better – but once you apply NR to the Sony image, the difference is levelled considerably. And this is the world’s best full framer for low light, right now, over 20 megapixels.

Here is your download link for Adobe Lightroom ACR 4.2 RC:

http://labs.adobe.com/downloads/lightroom4-2.html

And here is your link for ACR and DNG Converter:

http://labs.adobe.com/downloads/cameraraw7-2.html

The results at speeds from ISO 80 to 400 are a match for any DSLR, with the exception of the issue of dynamic range above highlight clipping. There is no significant margin for highlight recovery. This is a marked contrast to the early KM Sony sensor such as the 8 megapixel used in the Dimage A2, which had almost two stops of clipping-free highlight recovery using the metered exposure in high contrast situations.

Sony technology statement – new stuff all round

Posted on By

Whether you like it or not – and some aspects are going to be useful – Sony is rolling out a whole new generation of gear including advances in digital imaging. This is a long statement made at a press conference. It would take a long time to edit it, so here’s their text in full.

Sony Accelerates Revitalisation of Electronics Business by Enhancing User Experiences with New Product Offensive
 
Sony Corporation’s President and Chief Executive Officer Kazuo Hirai unveils an array of Xperia smartphones, a new Xperia-branded Tablet, VAIO PC, Wi-Fi camera, NFC-enabled audio devices, new applications, new musical partnership, a Book of Spells and a showstopping 84-inch BRAVIA 4KTV at IFA 2012
 
 
Sony Corporation (“Sony”) today unveiled a portfolio of advanced next-generation products which will help accelerate the revitalisation of the electronics business.

Kazuo Hirai, Sony Corporation’s new President and Chief Executive Officer, speaking at Sony Europe’s press conference at the IFA electronics show in Berlin, launched a range of compelling products – each emphasising Sony’s stated strategic focus on Mobile, Digital Imaging and Gaming.

“This is an extraordinary company going through extraordinary times. It forces us to confront difficult realities and make hard business decisions. We must look at ourselves honestly and hold true to the values and purpose of Sony. I am determined to do this with a laser-like focus, speed and execution,” said Hirai. “The products I unveil today will show Sony’s long-standing ambition to deliver what customers value – a simpler, easier, more entertaining and user-friendly experience.”

The range of new products announced in Berlin includes three new Xperia smartphones – one featured in the forthcoming James Bond movie ‘Skyfall’ – a new splash proof Tablet, a new hybrid slate/laptop VAIO PC, a new NEX camera with built in Wi-Fi enabling feature-adds post purchase, and enhanced NFC enabled headphones and audio devices.

Sony also unveiled a stunning 84-inch BRAVIA 4K TV, promising a totally immersive experience and building on Sony’s acknowledged professional expertise in 4K with acclaimed broadcast camera the CineAlta F65 and 4K cinema projection system.

Hirai vowed that each product would reflect the ‘One Sony’ ambition, the organisation’s drive to deliver technically-advanced products and compelling consumer experiences through greater synergies across all Sony’s businesses from electronics to games, movies and music.

“As “One Sony” we are joined together by a single vision, which I define with one particular Japanese word – Kando. It means to move people emotionally. Sony will bring a smile to the faces of a global audience” said Hirai.

MOBILE

Mobile devices are the gateway to Sony’s user experience. Adding to our acclaimed Xperia smartphones for providing premium entertainment experiences, Sony Tablets will be brought to market under the Xperia brand as of September 2012 to expand these great mobile experiences to the tablet arena.

The latest Sony mobile devices, including Xperia smartphones, Tablets and VAIO PCs, will boast Sony’s media applications, with the new interface designed to enhance the user experience in high picture and sound quality. It will enable users to enjoy and share music, photos, and movies in a simple and intuitive way. These features will be available across new Xperia smartphones, Xperia Tablet and selected VAIO PCs.

Furthermore, the new Xperia smartphones and VAIO PCs promise to bring consumers the ultimate cross-device connectivity. Through Sony’s One Touch function, which incorporates NFC (Near Field Communication) technology, users can easily and instantly enjoy their music and photos across an array of NFC enabled Sony devices by simply touching one device to the other without the need for Bluetooth or Wi-Fi set-up.

Introducing the new products, Hirai added: “Individual Sony products will entice and inspire people. But what’s also important is that by connecting and combining hardware, network services and applications, we will provide a truly remarkable and compelling experience.”

DIGITAL IMAGING

Sony’s mobile products are pioneering new ways to capture great digital pictures, whilst delivering an enhanced user experience through further, deeper convergence of hardware, content and services. The new NEX-5R model is the latest Digital Imaging product to deliver enhanced usability.

The NEX-5R compact system camera – with built in Wi-Fi – allows users to check the image, adjust camera exposure and control the shutter wirelessly from their smartphone. This makes it ideal for taking posed family pictures via the timer, where the image can be checked on the smartphone before the pose is broken. It also boasts “Fast Hybrid AF” giving DSLR-like focussing responses when capturing fast-moving action.

The NEX-5R is the first camera compatible with PlayMemories Camera Apps, a service for downloading new apps such as “Time-Lapse” and “Cinematic Photo” directly to the Wi-Fi enabled camera.

Sony is also introducing the new ‘wearable’ video camera, the HDR-AS15 with ‘ExmorR’ CMOS Image Sensor and SteadyShot image, great for skydiving or mountain biking.

GAMING

This autumn, Sony Computer Entertainment is due to launch Wonderbook, creating a multi-dimensional world using PlayStation Eye and augmented reality technology. It’s an experience like nothing else. The first Wonderbook title will be Wonderbook: Book of Spells, created in collaboration with J.K Rowling.

IN DETAIL

Detailing the product offensive at IFA, the Sony President and CEO highlighted the following innovations:

Xperia Smartphones

The integration of Sony Mobile Communications earlier this year was an important step for Sony. The company launched the first Sony smartphones to market earlier this year – the Xperia NXT (NEXT) series.

The next introduction is the Xperia T, Xperia V and Xperia J, building on the acclaimed arc design. They will be brought to the market over the next few months.

Xperia T is the new global flagship model that delivers the best high definition experience in a smartphone to date. It has a 4.6inch display powered by Sony’s Mobile BRAVIA Engine. Consumers can watch videos shot in Full 1080-pixel HD. The 13 mega-pixel fast-capture camera goes from sleep to snap in an instant with a single key press. The most amazing feature is how easily consumers can connect Xperia T to other devices to enjoy their content – with just one touch.

Xperia V is LTE enabled for super-fast network performance. It also comes with the highest level of water resistance in a smartphone, so users can continue using their Xperia V, come rain or come sunshine.

Xperia J is an eye-catching combination of stylish design and a stand-out screen size at a competitive price point.

Xperia Tablet S

The new Xperia Tablet combines a splash-proof body with high quality sound and a thinner, lighter design than its predecessor. It also offers a new app called ‘Socialife’ which enables users to enjoy SNS and news feeds in one viewer with a magazine-like layout. Together with new covers, stands and dock speaker, it is a communications device that will bring new style and fun into your life and appeal to customers of all ages and lifestyles. Running a NVIDIA® Tegra® 3 quad-core processor and Android 4.0.3 platform, it’s got all the power consumers will need to enjoy their favourite media, apps and games.

VAIO™ Duo 11

VAIO Duo 11 is a unique, Surf-Slider design hybrid PC which allows smooth sliding between slate mode and keyboard mode, ideal for being on the move. It features a thin, compact body with high performance, and a sophisticated stylus for the easy capture of handwritten digital notes, maximising the touch capability of Windows 8.

VAIO™ Tap 20

VAIO Tap 20, designed to leverage Windows 8, is a 20-inch, tabletop PC which tilts from desktop to lay-flat style. It can be a conventional desk top PC for personal use or a multi-media device – if used flat – for family use, for everything from playing board games to music editing or reading.

Audio Visual: ‘One Sony’ brings professional know-how and greater connectivity to consumer experiences

TV has always been part of Sony’s DNA, a symbol of constant innovation. It is the one product that still connects family and friends through shared experiences, more than any other.

Sony’s first 84-inch BRAVIA 4KTV

The new Sony 84-inch BRAVIA 4KTV boasts a 4K (3840 x 2160) LCD panel in the industry’s largest inch class (*1) and incorporates Sony’s ‘4K X-Reality PRO’ super-resolution high picture quality engine, meaning users will be able to reproduce a variety of content – including movies, TV programs, photos and games – to beautiful 4K picture quality ready to enjoy on the stunning 84-inch screen. This formidable combination seamlessly delivers a high-resolution large-screen picture with high-quality powerful sound to provide consumers with an immersive experience, unlike anything offered by existing televisions. The new BRAVIA 4K TV will be available worldwide, from the end of 2012.

*1: As of August 29, 2012.

Sony continues to take a lead role in advancing 4K technologies and is playing a leading role in professional 4K content creation through the CineAlta ‘F65’ camera, capable of shooting 4K content and beloved by leading film makers, and also the 4K digital cinema system used in the professional field. In the world of consumer electronics, the 4K home theatre projector for family use has been extremely well received since its launch last year.

The launch of the 84-inch 4K BRAVIA TV demonstrates the new and exciting consumer home-experiences made possible through professional technologies, advanced through the company’s ‘One Sony’ approach to hardware and content innovation.

HMZ-T2 Personal 3D Viewer

Lighter and more comfortable than its predecessor, the all-new Personal 3D Viewer from Sony is a head-mounted, High Definition 2D and 3D personal display with virtual 5.1 surround sound. It’s perfect for movies and gaming, with twin OLED screens that display vivid, super-sharp images (with zero cross-talk interference) to absorb consumers in a truly personal experience.

MDR-1 headphones

The new MDR-1 headphones are the result of collaboration between Sony Music artists and Sony engineers to deliver sound quality that accurately reproduces the original intentions of the musicians. The MDR-1 RBT is NFC enabled, and carries Sony’s One-touch function making it easy to share music across a range of NFC enabled devices by instantly setting up a wireless connection between devices, with just one touch. There is no need for any Bluetooth or Wi-Fi set up. 

SRS-BTM8 wireless NFC Bluetooth speaker

The SRS-BTM8 portable NFC Bluetooth wireless speaker from Sony lets you enjoy music from your smartphone or tablet in high quality audio, anywhere in the house. With its built in One-touch function from Sony, with just one touch to the top of the speaker with any NFC-enabled Xperia smartphone – including Xperia T and Xperia V smartphones from Sony – music will be streamed instantly. There is no need for Bluetooth set-up.

Partnership with Berliner Philharmoniker and Berlin Phil Media

Sony has extended its partnership with the world renowned Berliner Philharmoniker, and Berlin Phil Media, which offers the “Digital Concert Hall” streaming service. For the past two years, Sony has video-streamed Berliner Philharmoniker’s musical performances for customers worldwide to enjoy on Sony’s home entertainment products. Under this new partnership, Sony will also supply professional products, which incorporate its key technologies, whilst also providing technical support for the creation and streaming of Berliner Philharmoniker content through the service. This partnership will further enhance collaboration and innovation around audio development, and produce feedback which will be invaluable for Sony.

Sony HDR-AS15 action-cam

Ideal for sports lovers, the HDR-AS15 is a new type of camera; a ‘wearable’ video camera. It features Sony’s SteadyShot image stabilisation technology to deliver stunningly smooth footage which is ideal for filming sports scenes such as sky diving, mountain biking or snowboarding.

Equipped with built-in Wi-Fi, consumers can remotely control this video camera from smartphones and upload the recorded data online immediately. It also features a 170° wide angle Carl Zeiss lens.

New NEX models – downloadable apps for camdroids!

Posted on By

The age of the camdroid is upon us! Sony has, as expected, announced a platform to flog unsuspecting owners small programs which are not even big enough to get the name of applet and are reduced to mere apps. Owners will be able to download new stuff to use the hugely powerful processors inside the new generation of WiFi equipped, net-browsing, smartphone friendly digital cameras.

The rear view of the new generation of Sony DSC (Digital Still Chimera) showing the PMCA App_store – well that’s how the picture is named, but we suspect that if Sony uses terms like ‘app’ and ‘store’ together the world’s most cash-bloated corporation will come in hot pursuit. Expect battle lines to be drawn up somewhere between San Diego and San Francisco. They could meet in LA to fight it out. The photo above is made using an app which applies orange fake tan to any hands shown holding a camera.

Here’s the press info from today’s conference:

More ways to enjoy the memories
 
PlayMemories family of apps and services from Sony gains exciting new features
PlayMemories from Sony keeps growing with a series of exciting new possibilities to enhance your digital imaging experience, before and after shooting.

PlayMemories is an easy-to-use family of services and applications that lets you enjoy photo and video memories across multiple devices – from cameras, smartphones and tablets to PlayStation®3 and compatible BRAVIA TVs.

PlayMemories Camera Apps

PlayMemories Camera Apps is the world’s first application download service（for interchangeable-lens digital cameras as of August 2012）that lets you install new functions on demand to boost the capabilities of your camera.

PlayMemories Camera Apps offers a variety of applications that expand camera functionality, personalising your photographic experience and enhancing your network connectivity. Just download the applications onto your camera and start enjoying even richer photographic expression.

PlayMemories Camera Apps is initially supported by the new NEX-5R interchangeable lens compact system camera. From launch, there’s a range of imaging apps to broaden your creative options and utilities.

“Picture Effect+” expands the range of artistic treatments available in the camera’s standard Picture Effect mode. “Bracket Pro” automatically shoots a rapid burst of three images at different ‘bracketed’ settings – for shutter speed, aperture or focus – allowing you to choose the best shot. “Multi Frame NR” captures a series of images in rapid succession. They are automatically superimposed by the camera to create one low-noise photo at the selected ISO speed. It’s ideal for capturing atmospheric night-time scenes, or shooting in dark conditions without using flash.

“Photo Retouch” adds a generous palette of adjustments like brightness, saturation and contrast plus Soft Skin, re-size and other post-shooting effects. Also available is the Auto Portrait Framing feature which detects the faces in images captured and intelligently applies the recommended composition afterwards.

Sony also plans to introduce more new apps, including “Time-lapse” and “Cinematic Photo”. “Time-lapse” automatically captures a series of still pictures at adjustable intervals. These images are automatically combined by the camera, and can be replayed like a video clip. “Cinematic Photo” captures a series of frames, creating fun animated picture effects where part of a static image appears to move.

Downloadable utilities include “Smart Remote Control”: remotely check the image on screen, adjust exposure and release the shutter of the NEX-5R with your smartphone1 or tablet (such as the Xperia™ Smartphone and Xperia™ Tablet). Captured pictures are also sent automatically to your smartphone or tablet. “Direct Upload” lets you upload images directly from the camera to PlayMemories Online and Facebook.

New PlayMemories Camera Apps will be initially available in the UK from October 2012.

PlayMemories Online

From this August, Sony’s compatible BRAVIA TVs will become able to view photos and video posted on PlayMemories Online directly, broadening the width of devices capable of enjoying the service.

PlayMemories Mobile

This Android/iOS app simplifies video and photo transfers to smartphones or tablet devices from the Wi-Fi enabled cameras such as the NEX-5R compact system camera. As detailed above, the app now lets you remotely control the NEX-5R and the HDR-AS15 Action Cam using your smartphone: it’s great for family group shots where you want to be in the picture, too. (“Smart Remote Control” app needs to be installed to the NEX-5R to use this feature.)

PlayMemories Studio

PlayMemories Studio makes organising, editing and viewing videos and photos on your PlayStation®3as easy and intuitive as playing a game.

PlayMemories Studio2 evolves with the brand-new ability to output images on Sony’s 4K TVs. 4K displays contain around four times more detail than Full HD. You can enjoy high resolution images taken by current digital cameras on Sony’s new 4K-enabled BRAVIA KD-84X9005.

Other enhancements include easy content uploads to YouTube and PlayMemories Online.

For further information on PlayMemories Camera apps, please visit: www.sony.net/pmca

1 Requires download and installation of PlayMemories Mobile™ app on Android smartphones and tablets as well as iPhone and iPad.

2 Available starting during current fiscal year ending March 2013.

October sale date for NEX-5R

Posted on By

Sony has released information about the NEX-5R, which goes on sale in October. Most of this was already known beforehand, we think there’s a press conference happening in Iceland, but it’s cold enough here so photoclubalpha is not upset to be missed off the roster. And that may just be a myth.

Sony text:

More imaging power, less to carry
 
NEX-5R compact system camera from Sony debuts “Fast Hybrid AF”, Wi-Fi and PlayMemories Camera Apps
  • DLSR-quality images and Full HD video from newly-developed, large 16.1 effective megapixel APS-C image sensor
  • New Fast Hybrid AF for fast and precise autofocus in any situation; DSLR-like AF tracking for shooting at up to 10 fps
  • Download new features through built-in Wi-Fi with PlayMemories Camera Apps TM , the world’s first application download service*
  • 180° tiltable LCD touchscreen for self-portraits with ultra- compact body

 

Serious picture performance, style and portability are blended beautifully in new NEX-5R compact system camera from Sony.

Combining big-sensor image quality with the freedom of interchangeable lenses, the hybrid mirrorless camera offers all the benefits of DSLR-style imaging with less to carry. A power-packed step-up from your point-and-shoot compact, it’s also a perfect second camera for photo enthusiasts who won’t compromise on image quality or control when they’re travelling light.

With a resolution of 16.1 effective megapixels, the DSLR-sized sensor assures richly detailed still photos and crisp 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 sensitivity settings up to ISO 25600.

In a first for interchangeable lens cameras by Sony, Fast Hybrid AF combines phase- and contrast-detection autofocus methods to suit the demands of any shooting situation. First, phase-detection AF quickly detects subject distance; then contrast-detection activates to confirm extremely fine, precise focus.

In Speed Priority Continuous mode, the NEX-5R switches automatically to 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 F4-6.3 OSS; E 18-200mm F3.5-6.3 OSS; E 24mm F1.8ZA Sonnar T*. Firmware upgrades will steadily expand the range of lenses offering Fast Hybrid AF support.

Framing, adjusting, shooting and viewing images is a pleasure on the intuitive touch-screen LCD. It’s complemented by a fully-featured control dial and function button: a versatile combination for any photographer who’s accustomed to the flexibility of their DSLR camera. There’s also a new touch shutter function that makes it easier than ever to pick your perfect moment.

The clear, bright touchscreen flips through 180 degrees for easy arm’s length self-portraits. Enthusiasts will also welcome the switchable on-screen digital level gauge that helps keep horizons level with landscapes and architectural shots.

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

The NEX-5R is the first α interchangeable-lens digital cameras by Sony with integrated Wi-Fi capabilities for easy image sharing, saving and viewing. Photos and videos can be transferred wirelessly to any smartphone or tablet that’s running the free PlayMemories Mobile app.

Alternatively, transfer all those memories directly to a networked PC, simplifying image back-ups without having to fiddle with memory cards or connecting cables. Photos stored on the NEX-5R can also be enjoyed directly on any DLNA-compatible TV, with no HDMI cable needed. Share via your wireless access point, or bypass your router and send pictures straight from the camera to TVs supporting Wi-Fi Direct.

The NEX-5R even lets you upgrade the camera’s capabilities any time to suit your shooting needs. Brand-new PlayMemories Camera Apps is the world’s first downloadable service1 that lets you install new functions on demand. You just need to connect the camera to your PC via USB or directly over Wi-Fi to do this.

From launch, available apps include “Picture Effect+”; “Bracket Pro”; “Multi Frame NR”; “Photo Retouch”; “Smart Remote Control” and “Direct Upload”. Sony plans to provide more new apps, such as “Time-lapse” and ”Cinematic Photo” in the near future.

New accessories include the slim style Soft Carrying Case LCS-SL10 – which is the ideal camera bag to carry your spare lens and accessories for casual outdoor use – and the Screen Protect Semi Hard Sheet PCK-LM13 with anti-fingerprint coating to beautifully protect your LCD screen.

Should NEX go full frame?

Posted on By

Sonyalpharumours has posted a firm rumour that there will be a full-frame NEX. Anyone who understands the design of camera bodies, and the geometry of optical projection, has known from the start that this was possible given the design of the E-mount.

Those who have made uninformed comments (all over web forums!) to the effect that the rear register is ‘too short’ or would cause problems simply don’t have their brains switched on. There is no such thing as a camera body which is too thin or a mount to focal plane register which is too short.

Sony already designs lenses for NEX APS-C which incorporate what amounts to an extension tube to push the rear nodal point and exit pupil positions as far forward as needed for optimum illumination and matching of off-axis ray bundles to the sensor’s microlenses, filter array and cover glasses. That’s why the 30mm Macro is not so very different in size from putting a 30mm f/2.8 Alpha SAM macro on an adaptor (and that’s why we do exactly that here!).

What matters for full frame is a correlation between the clear lens throat diameter (the bayonet mount inside width), the sensor size, and the register.

The NEX system uses an 18mm register. That is the term of the distance between the front surface of the bayonet mount on the body (or rear surface of the mount on the lens) to the sensel layer surface of the sensor. There is a very small adjustment made in all digital cameras for the four physical layers which usually go between the sensor and the lens: the RGB filter layer (so thin it has no effect), the microlens layer (again, no effect), the low-pass or anti-aliasing filter and the infra-red cut and protective self-cleaning outermost glass. These filters may be combined into a single glass but in NEX they remain separate.

The sensor requires an image circle of just under 30mm allowing for assembly tolerances of 0.5mm overall in positioning and conformance of the lens axis. If in-body stabilisation is used, this diameter must be increased to 35mm at least; some Konica Minolta documentation suggests that a clear diameter closer to 40mm was needed for the original AS/SSS.

For full-frame, the required image circle is 44mm and the maximum diameter for in-body stabilisation could be between 49mm and 54mm depending on how Sony’s statements about sensor travel are understood (“5mm in any direction” could mean the total scope is 5mm, or that 5mm travel from axis might be possible). A good idea of the actual travel of an APS-C sensor with IBIS is given by the Pentax K-5, which has a manual sensor shift function allowing the user to move the sensor off-axis for a slight rising or cross front effect – but only by 1.5mm. This sounds more realistic though it would, of course, be a great feature if you could shift a sensor 2.5mm or an extreme 5mm – every lens with enough coverage would become a PC lens!

Now let’s compare these image circles with the lens throat diameter and its distance from the focal plane.

The Alpha system has a register of 44.5mm and a clear lens throat internal diameter around 42mm. Allowing for the orientation of the film plane and the position of control connections and the electronic contact array, the Alpha mount ends up providing an almost exact fit for the optical projection path if a 45mm diameter image circle is needed. Even if a 2000mm non-telephoto lens was attached, its image would cover the sensor without physical shadow vignetting caused by the mount.

It is important to remember that a 44.5mm register allows space for the reflex mirror, but also allows the image forming light to spread out from a rear element positioned over a wide range of possible distances, from just inside the camera body (by about 5mm before the mirror would hit it) to a good three or four centimetres in front of the mount. This allows a larger overall image circle and indeed most SLR lenses produce one greater than 50mm diameter. That’s how the Alpha 900/850 is able to offer in-body SSS, and also why certain lenses show vignetted corners occasionally when SSS is active because their image circle is only just sufficient to cover the sensor in its central, parked position.

This is a very accurate representation of 24 x 36mm sensor areas excluding any of the surrounding assembly, showing that the internals of the E-mount could be modified to fit FF. The white line shows the 24 x 36mm in the sensor plane, relative to the APS-C sensor. The red line shows the 24 x 36mm sensor as it relates to the mount, in the flange plane. The two rectangles are needed to show the size accounting for the perspective of the macro lens used to take this shot.

The NEX E-mount appears to have not much smaller a diameter, but this is deceptive. You need to look INSIDE the mount and study the position of the electronic contact pins. Once these are considered, the actual clear diameter is not 46mm at 18mm from the sensor (apparently bigger than the A-mount) it is 39mm at 12mm from the sensor. The contacts are located 5mm into the camera body and occupy a clear 3mm zone. The outermost contacts in the array are positioned  sufficiently far from the extreme corner of a theoretical 24 x 36mm sensor to allow a full frame design, assuming most of the other detail of the darkchamber design is changed to ensure the widest possible clear area.

Ideas about putting SSS and full frame into such a NEX are wishful thinking, unless the camera was to be huge and the possibility of the lens mount innards shadowing part of the image was accepted. There’s just enough room to fit a full frame sensor, and no more.

It is more likely that Sony would introduce a range of new full-frame lenses with OSS, or non-stabilised adaptors for Alpha lenses designed to allow an unrestricted light path. It is also possible that a stabilising optical adaptor could be made, but we’d put that as the least likely option and one which would probably cost over $1000. Sony would more likely to put an electronic pixel-shift IS into a full frame NEX, though at present this only works with video and imposes a slight crop (1.87X) on what would be the maximum 16:9 frame area.

As for suggestions that existing NEX lenses might cover full frame, that is also uninformed speculation. They won’t and don’t. The same applies to the LA-EA1 and LA-EA2 adpators – neither of these would allow Alpha lenses to be used on the NEX and cover full frame, though there are a few wide angle lenses which might just squeeze their image through the small internal baffles. A few of the third party adaptors for lenses such as Leica M might allow coverage, some would not, depending on exactly how the light baffles and inner mount components have been designed. For APS-C NEX, it pays to add baffles which prevent stray light and flare; for FF NEX, the same baffles might vignette the image.

The question of sensor design is another matter, but it can be assumed many owners would use a full frame NEX to host legacy full frame lenses from a wide range of systems. Most of these have a degree of telecentricity which removes corner colour shifts. New full frame NEX lenses would be designed to match the new sensor, so that would not be an issue. Old rangefinder lenses would have no more problems on full frame NEX than they do on, say, a Leica M9. Sure, there would be issues, and weak combinations alongside strong ones.

These would not over-ride the value of a full frame NEX body. Good photographers can use any format well. They do not demand ‘the full frame look’ or believe that any one format is going to change their work in some way to make it superior to others. There’s a place for every format and choice is a good thing. End of story.

Canon transforms 7D – why can’t Sony do the same?

Posted on By

Version 2 firmware for the Canon EOS 7D released today so much transforms and upgrades that camera that it makes the lack a replacement – at least until after photokina – no concern for owners. Indeed, owners will be thanking Canon for giving them what amounts to a new camera free of charge.

Whether or not Canon’s approach to firmware coding is very different, and gives them much better access to tapping new functions, we do not know. But this is not some small tweak. It adds the one vital thing which could make the Alpha 77, 65, 55 (etc) and NEX-7 attractive to video makes – manual control of audio/mic input gain.

That single improvement answers many Canon owners’ demands, as lesser models within the Canon range, introduced after the 7D, have had a full two-channel level adjustment display.

The upgrade goes further and adds in-camera RAW editing, which surely must have required a processor capable of this from the start, and JPEG resizing plus image rating (these two functions when combined allow preparation and selection of images for transmission to client, newsdesk or printer hosts).

Here is the full info:

Canon today announces that the EOS 7D firmware v2 is now available, adding a range of new benefits and functionality for enthusiasts looking to explore the creative boundaries of their photography. Following direct user feedback from photographers around the world, the new firmware further extends to the camera’s advanced image quality, high speed shooting and creative functionality.

Firmware v2 now offers greater control of image settings and functionality, including a higher maximum RAW burst rate, now up to 25 RAW files or 130 JPEGs. Giving photographers greater control over images directly after capture, a new range of in-camera editing functions includes processing of RAW files, as well as the ability to easily adjust white balance, sharpness and Picture Style.  Enhanced control over Auto ISO levels during both still and movie shooting now allows users to limit ISO speeds to within the native ISO 400-6,400 range, perfect for manipulating exposure in different situations.

During movie shooting, amateur videographers will also benefit from new manual control of audio levels, with the ability to choose from 64 different sound levels. New compatibility with Canon’s high-performance GPS unit, the GP-E2, enables photographers to track the locations of their images using longitude, latitude and altitude geo-tagging.

Firmware v2 is available to download now from: http://software.canon-europe.com/

Canon EOS 7D firmware v2 – new features:

·         Improved maximum burst for RAW images (up to 25)

·         In-camera RAW image editing

·         In-camera Image Rating

·         In-camera JPEG resizing

·         Maximum Auto ISO setting (ISO 400-6400)

·         Manual audio level adjustment in movie recording

·         GPS compatibility

·         File name customisation

·         Time zone settings

·         Faster scrolling of magnified images

·         Quick control screen during playback

(end of Canon copy)

Now Sony – can you step up to the mark, show that you have spent just a few dollars of the money acquired from the sale of Alpha and NEX system on human resources aka software and firmware programmers, and reward the loyalty of your owners with an audio fix on all camera, max/min auto ISO where missing, in-camera RAW processing…

Gary Friedman workshops in UK, September 13-16th

Posted on By

Gary Friedman, who is well known for his excellent e-books on the Alpha system (new one just out, Alpha 37 and 57) lives on the sunny, foggy, funky coast surrounded by surfing dudes and dudesses, just south of the vast conurbation of Los Angeles.

But having several million photo enthusiasts on his doorstep is not enough. He’s hitting Britain’s shores in September to give one talk near Portsmouth on the 13th (the commute will be a refreshing experience after the multilane highways of home) and two full day seminars in Kingston-on-Thames (15th and 16th). We are, I’m afraid, responsible for Gary locating these in the little-known but lovely Antoinette Hotel, a conglomeration of former houses in a quiet residential area only a short walk from the Thames and some rather good waterfront pubs. It has a large car park, you can walk from the station, and you can even get there by riverboat if you can work out how on earth to plan the journey.

Whatever the case, Gary’s talks are not to be missed. He has agreed to join us as US Associate Editor on a new publication venture – Cameracraft, a quarterly magazine which may follow in the wake of Photoworld, but has no affiliation to camera brands or clubs. You can find a subscription link to Cameracraft, which should be in print just in time for Gary’s dates, on our left hand sidebar (there’s much fuller info in our Links).

So, check up on Gary’s web page – even his taster and programme for the seminars can teach you more than you think.

Sigma ultrawide zooms – old and new 12-24s versus 8-16mm

Posted on By

For almost a decade the Sigma 12-24mm full frame ultra wide angle zoom has been unrivalled by any other makers – not Nikon, not Canon, not Tamron, not Tokina, not Sony. No maker has ventured where Sigma went, to the extremes of over 120° coverage combined with well corrected straight line geometry.

Today, the original 12-24mm is in its fourth incarnation, having progressed through EX to EX DG (digital) and then with added HSM hypersonic motor focusing, which never arrived for Alpha mount in the original design. The fourth version is an entirely new design, and does have HSM for Alpha. It is very similar to the new 8-16mm design, introduced three years ago for APS-C cameras, which also offers HSM focusing in Alpha mount.

Update five years later, 2017: there is now a constant aperture 12-24mm f/4 ART lens. This is a completely new design and has an almost-perfect performance, especially in terms of corner detail wide open. I’ve tested it in Cameracraft magzine. However, I did not have the various older models to make direct comparisons. The MkII remains available as the current non-ART, lower priced Sigma option.

Here you can see, from left to right, the EX DG 12-24mm f/4.5-56, the DC 8-16mm f/4.5-5.6, and the DG HSM II 12-24mm f/4.5-5.6. Don’t be fooled into thinking the original is wider in diameter, it actually shares exactly the same lens cap module as the new design; it’s smaller and around 100 grams lighter. Both the 8-16mm and new 12-24mm are surprisingly solid items.

First, we’ll look at the difference between old and new 12-24mms. I have used the old one in several versions on several different camera makes. and I’ve never had one which was truly sharp at all point across the frame wide open. The field is not perfectly flat, and autofocus modules are very bad at getting an exact focus at 12mm. Combined with lens mount tolerances, sensor flatness problems (mostly in Canon full-frame, which historically have not had very ‘plane’ sensors), sensor parallelism problems (all makes, Sony not excepted)… it was always a good idea to stop this lens down to f/11.

How bad is that? Perfectly normal for any lens covering over 85°. Even the best large format lenses, single focal lengths like Super Angulons, have always been used in the awareness that full aperture is for focusing and you stop down to between f/11 and f/32 for the actual shot. On 35mm format digital, using anything much below f/16 is counter productive for sharpness and my normal choices on the Alpha 900 have been f/10, f/11, or f/13.

The good news is that the latest version has a different kind of field flatness. The old one tended to have a zone, like a doughnut, of closer effective focus surrounding a sharp middle. At 24mm, where this older lens performed at its worst, this zone was pushed out to the far edges and could result in the corners looking softer than they do at 12mm. The new one has a simple barrel distortion in place of a wave-form distortion, and along with this goes a simple curvature of field.

The bad news is that the overall level of distortion is much higher than the old design. At 12mm, it’s close to needing the fingers of two hands. Adobe Camera Raw had a correction profile for this lens from Sigma almost the day it became available. That profile fixed the distortion perfectly but leaves you slightly less of a 12mm than you’ve paid for, because it reduces the angle of view.

Here are some comparative views. First of all, I’ve used only 10 megapixels of the Alpha 900 frame, cropping from the top of a vertical shot, to get this architecturally correct view. This is like using the 12-24mm as an extreme 12mm shift lens on an APS-C camera. As and when we get a 36 megapixel Alpha full framer, the crop to do so will be more  like 16 megapixels. This is the full frame:

Below you can see the crop used to 10 megapixels, and by rolling your cursor over the image, the change between a profiled conversion and a raw conversion with no lens corrections. On this crop it does not look extreme.

But this is a relatively kind way to use the new lens. Here is an example pushing straight lines into places where extreme wide angles don’t like ’em:

This is an uncorrected 12-24mm DG II HSM shot out of the Alpha 900 at 12mm. It’s not exactly what you want, and in fact, it’s not as ‘good’ as the old design despite being sharper. Hovering your cursor over the image shows the same raw file with the Adobe Camera Raw Sigma-generated Lens Profile (also works in Lightroom) applied. As you will see, straight lines have been restored along with even illumination. But – how much of that 12mm, 122° angle has been lost? Is it now really only a 12.5mm?

In practice, the new 12-24mm gives you a great range of creative choices when confronted with a building. Here is a revisit to the first subject, taken at different focal lengths, getting closer to the building with each shot:

24mm

20mm

17mm

15mm

12mm

When it comes to comparisons with the older design, the new one is much sharper at the edges. It does not need stopping down to f/16 to pull in the worst aberrations, though it does still display some around f/8 to f/11. Here’s an original 12-24mm EX DG design shot (12mm, f/9, vignetting corrected but distortion not corrected):

And here’s the new 12-24mm under the same conditions (small exposure difference due to changing light) processed similarly, without any geometric corrections:

On this shot, the corrugated barn sides have clean ribbing to the extreme ends, with some softening; on the old design, they begin to look a bit of a mess in the outer quarter of the frame.

Trying the 8-16mm extreme

But when doing these tests, I decided to throw a novelty into the mix. What if I put my 8-16m APS-C format Sigma DC HSM zoom on to the Alpha 900? Because it is not an Alpha lens, the 900 does not automatically crop the full frame. This is what I actually got with the lens set to 8mm:

And in Adobe Camera Raw, I just dialled up the Scale in Lens Correction to 146%, which blew up the central 12 or so megapixels of the frame to become a full 24 megapixel image:

And here, for comparison, is what the 12-24mm set to 12mm could produce:

This is a little tighter than the 8mm using the maximum I could get (including some extra image height), so the 8-16mm used this way can produce something closer to an 11.5mm full frame lens. However, I have not yet done the obvious – to get an engineer to remove the petal lens shade from the 8-16mm (it appears to be part of the front element assembly). This would enable even more angle without shading, and the possibility of square or 10 x 8 shape format crops.

What was particularly interesting about this experiment was the quality of the 24 megapixel file extracted from a smaller section of the Alpha 900 sensor by Adobe Camera Raw upscaling. Full size files are available to download for subscribers to Photoclubalpha – it’s well worth the $10 for a full year of access to any of the extras we provide. See the download links at the end of the article, which will become visible if you are a registered subscriber to the site.

The 8-16mm also achieves full frame coverage on the Alpha 900 when set to 16mm, though with fairly marked vignetting:

Here are some more samples from the 12-24mm DG II HSM: first, 17mm at f/8 – no geometry correction:

Next, at 12mm at f/13 which on the A900 seems to be the limit for good detail sharpness without extra effort in processing:

And 17mm at f/22 – beyond the diffraction limit, but processed carefully for detail:

And 12mm at f/9, an optimum setting for detail with plenty of depth of field for this subject:

So, what was my own decision? I own the 8-16mm and an Alpha 77. That’s what I use for travel and general work. I own an original EX DG 12-24mm. I decided not to buy the new 12-24mm because I concluded that the 8-16mm used on APS-C was effectively as good. The angle is not quite a match for the 12-24mm on full frame, as APS-C is not a true 16 x 24mm. For those occasions where a 12-24mm on full frame is needed, I’m nearly always able to work on a tripod at f/13 and focus manually (which overcomes most of the issues with the earlier lens). Since it needs less drastic geometric correction, it offers a very small angle of view advantage over the new lens in return for the risk of poor sharpness if not used well stopped down. I have no doubt the new lens is better, but it’s not £400 better which is what the ‘trade-up’ would cost – and the old lens is lighter and smaller, which I appreciate.

The test made me even happier with the 8-16mm, especially with the thought that some modification could make it a unique lens to use on the Alpha 900 or a future full frame EVF model (A99). After doing these tests, I decided it was not necessary to take the Alpha 900 and a 12-24mm despite the investment in two weeks’ shooting in the Sierras and Pacific Coast of California – the A77 and 8-16mm would do everything I needed.

But for those buying a 12-24mm, for full frame on any system, the new Sigma represents even better performance than the 8-16mm (better edge and corner sharpness at one stop down from wide open) and has none of the failings of the older lens even if it does need more post-process geometry correction.
