HD videocast – NEX adaptors and odd lenses

I’ve finally got round to trying a ‘proper’ videocast – perhaps the first of regular short demonstrations – with the Alpha 55 offering me HD filming while demonstrating the NEX-5. And I can use the NEX-5 to film stuff about the Alpha 55. A Canon 60D helped, though its inability to refocus during filming (which the NEX-5 and Alpha 55 can do) proved a small problem. The sound from the Canon was used, mainly because it had been set with a manual level, while the Sony was using an external condensor mic that pickup up some serious interference from the lights.
The lighting is nothing more than one 30W daylight colour energy saver and one 20W – using an angle desk lamp from IKEA and a spare table lamp. The background is a Calumet (Lastolite in disguise) canvas. To do the filming, I ran a 7 inch Lilliput monitor from the HDMI output of the Alpha 55, and mounted it facing me on a bar right next to the camera. The Canon was set up as a second camera and left running from that position. Editing, including cutting and pasting the soundtrack and parts of the Canon video, was in iMovie 11.

This is a full 1080p HD YouTube film – if you can view it (bandwidth is an issue) try the higher resolutions. The Alpha 55 consistently overheated at around 7 minutes, showing me a temperature warning then shutting off. The room was not warm and the camera screen was both not active, and moved away from the camera back. My first attempt at this film was spoiled by the overheating issue, perhaps because SSS was left on in error. However, on a tripod SSS is not active to any extent when shooting video (it does not have the same problems of creating blur, which happen with still images due to the way mirror or shutter vibration are reflected by the tripod). Previous time limited movies I’ve made have been hand held and of course SSS is both used and expected to be very active.

Sony VAT-back offer – UK only

Many Sony Alpha products are included in the Sony UK VAT-back scheme which will operate until December 24th. Items purchased from authorised retailers from October 28th onwards may be eligible for a claim, and Sony will return the equivalent of the 17.5% VAT paid to the customer directly.
This is not actually VAT back, as any item purchased in this way is still eligible for normal VAT relief on the nett amount paid, for UK VAT registered buyers (businesses). Customers outside Europe will be able to buy without VAT under the normal rules applying to exports.
On January 4th 2011, UK VAT increases to 20% for consumer goods including all the Sony range.
For details of the VATback offer, see:
http://www.sony.co.uk/hub/1237479399273
Sony point out that the VAT amounts to 14.9% of the price paid, not 17.5% (it is 175/1175).
The offer includes  NEX-5, Alpha 580, Alpha 55 and Alpha 33 plus two lenses – the 75-300mm SAL and the 50mm f/1.8 SAM. But you need to be very careful indeed when ordering, as the deal applies only to some very specific packages such as the Body Only for A580, A33 and A55 (if you can find it!) and exact kits such as NEX-5D with 16mm and 18-55mm or NEX-5A with just 16mm. You must check when buying whether the exact product number you are buying qualifies for the VATback.
Buyers internationally can also get similar discounts until December 31st – we note that B&H for example offers this NEX-5 kit with $150 rebate. That’s about the same as the UK VATback deal.

NEX firmware upgrades released

Sony has released the firmware upgrades which were promised at photokina for the NEX models NEX-5 and NEX-3, and the Alpha mount lens adaptor LA-EA1.

Photoclubalpha readers in Europe can download the firmware upgrade from:
http://support.sony-europe.com/hub/hub.html
Autofocus is now supported when using the NEX-5/NEX-3 with 14 lenses from the full range of A-mount optics by Sony and Carl Zeiss that includes telephotos, primes and zooms. Aperture settings can be maintained during HD movie recording, and system menu operation has been streamlined alongside other usability improvements. Registered NEX-5/NEX-3 owners will be advised of the free update via email.
Autofocus with A-mount lenses
Single-shot autofocus is supported with 14 optional A-mount SAM and SSM lens models3 when used with the optional LA-EA1 Mount Adaptor. Single-shot AF is also possible while in movie recording mode by pressing the shutter button halfway down. Support for AF operation with A-mount lenses also requires a separate firmware upgrade for the LA-EA1.
Aperture priority with video recording
HD video can be shot while maintaining constant aperture, either in A (aperture priority) mode or in iAuto mode with background defocus activated. This aids the simple creation of beautiful background defocus effects during movie recording.
Soft key settings
It’s possible to customise functions of two of the three soft keys on the camera’s rear panel. Functions that can be assigned include Shooting Mode, Shooting Tips, Precision Digital Zoom, ISO, White Balance, Metering Mode, Flash Compensation, DRO, Auto HDR, Creative Style, MF Assist and AF Area.
Menu start
When ‘Menu’ is selected, there’s now the option to display either the main menu screen or the last parameter set. This simplifies quick readjustment of recently-selected functions and settings.
MF Assist
An enlarged image portion can be displayed on screen with user-selectable duration while in MF (Manual Focus) Assist mode. MF Assist operation has also been improved. The previously-chosen magnified image portion can now be maintained when MF Assist is re-selected, making repeated checks of fine focus quicker and more convenient.
System requirements
PC: Windows XP SP3 (64-bit and Starter editions not supported); Windows Vista SP2 (Starter edition not supported); Windows 7
Macintosh: OS X Ver.10.5 or later
All platforms: Hard disk space: min. 200MB / RAM: min. 512MB.
Upgrade requires USB cable connection between computer and NEX-5/NEX-3.
Autofocus function is supported with these A-mount lenses:
SAM lenses
• DT 18-55mm F3.5-5.6 SAM [SAL1855]
• 28-75mm F2.8 SAM [SAL2875],
• DT 55-200mm F4-5.6 SAM [SAL55200-2]
• DT 30mm F2.8 Macro SAM [SAL30M28]
• DT 35mm F1.8 SAM [SAL35F18]
• DT 50mm F1.8 SAM [SAL50F18]
• 85mm F2.8 SAM [SAL85F28]
SSM lenses
• Vario-Sonnar T* 16-35mm F2.8 ZA SSM [SAL1635Z]
• Vario-Sonnar T* 24-70mm F2.8 ZA SSM [SAL2470Z]
• Distagon T* 24mm F2 ZA SSM [SAL24F20Z]
• 70-200mm F2.8 G [SAL70200G]
• 70-300mm F4.5-5.6 G SSM [SAL70300G]
• 70-400mm F4-5.6 G SSM [SAL70400G]
• 300mm F2.8 G [SAL300F28G]
AF support also requires firmware upgrade for optional LA-EA1 Lens Mount Adaptor.
With an A-mount lens attached to NEX-5/NEX-3, autofocus takes approximately 2 to 7 seconds based on Sony measurement standards. Actual AF time with A-mount lens may vary depending on the subject and shooting conditions.

Sony Photokina Press conference video – in full

We filmed the entire Sony press conference at photokina. It is split into three sections about 7 minutes each. During filming using the NEX-5, the camera at one point started to show an overheat warning. At this point I should have moved the articulated screen away from the camera body, but did not want to interrupt a very important moment – the announcement of the A7xx. And that’s when it cut out, taking maybe 10-15 seconds for me to move the rear screen, wait a moment, and restart.
Here are the videos. They are all at 720p quality and uses the internal mic, not the add-on mic, as I was ‘travelling light’ for this conference.

NEX firmware update details in full

Please see this page for details of NEX full-frame compatibility: http://www.photoclubalpha.com/2012/08/19/should-nex-go-full-frame/. Further information updated August 19th 2012: Paul Genge left Sony UK on Friday August 18th 2012, after many years with Minolta, Konica Minolta and Sony in turn. He is setting up his own website company.
———————————————————————————————
At photokina 2010, Paul Genge of Sony UK was able to show me his NEX-5 with the new firmware v3 installed, but not to provide any copy of the firmware or update my own NEX-5.
Once installed, the firmware provides new Custom Menu assignment options.
Button B (Soft Key B) which is the lowermost button, can be assigned a function from the following list:

  • Shoot Mode
  • Shoot Tips (the existing default)
  • Precision Digital Zoom (teleconverter)
  • ISO setting
  • White Balance
  • Metering Mode
  • Flash Compensation
  • DRO/HDR
  • Creative Style
  • MF Assist

Button or Soft Key C (the centre conroller button) has three Custom Memory registers. After reprogramming the button, you can then access three different new functions using the surrounding controller.
You can set the Memory registers to a selection of three of the following:

  • AF Area
  • ISO Setting
  • White Balance
  • Metering mode
  • Flash Compensation
  • DRO/HDR
  • Creative Style

or nothing (you do no have to assign a function to all three Custom Memory registers).
Therefore, in addition to the existing direct control of exposure compensation from the main controller, the Centre and Bottom buttons can between be assigned four rapidly accessed different vital functions.
For Aperture priority video, the procedure could not be simpler; just set Aperture Priority mode, select the aperture, press the Viedo button and you get that aperture.
Autofocus is enabled with SSM and SAM lenses. When the new A700-series model appears, Paul confirmed that it will look quite different from the mock-up shown at PMA and again at photokina. All the clues I can get indicate that it does indeed use the same basic internal system as the A33/55, and will have an EVF. But Paul said this camera will include such high specification features that current A700 owners will be amazed.
Two more comments he made are worth relaying. Asked whether there would be no further development of the full-frame range, Paul said they intended to complete the A3/5/7 developments and would then turn their attention to new full frame, including an Alpha 900 replacement with features yet to be decided. He pointed to the new 500mm f/4 G SSM, shown in bare metal and with paint on, as evidence of their intentions. Also, it was possible to create a full frame NEX, using the same mount and the A-mount adaptor, but never the same lenses as the APS-C NEX. The mount had been designed to allow this and it might one day happen, in which case full-frame adapted Leica lenses (and so on) would be even more useful.
The new standard zoom lens (16-80mm replacement) could be SAM not SSM. Paul pointed to the ring on the front of the mockup (gold ring – a bit of a Tamron-type clue?) and suggested that this could mean the SAM motor.
The Sony stand showcased many examples of converters (especially the high quality products from Novoflex and Voigtlander) and showed many ‘alien’ lenses from new to old fitted to NEX bodies. In the meantime, Carl Zeiss filled their stand with Sony bodies ro demonstrate CZ lenses – their own stand staff were using NEX-5 (on guy had a 35mm Biogon fitted) and for demonstration, both A55 and A900 were fitted with the new 24mm f/2 CZ, NEX was fitted with 16-80mm, A900 with 135mm f/1.8 – and many more combinations.
Wherever I went, the NEX was in evidence, perhaps more amongst members of the trade and dealer staff than amongst the photographer visitors who (as at all trade shows) lumbered around with Canons and 70-200mm f/2.8 lenses.

Sony affirms NEX future – and SLT path for Alpha

Sony today announced upgrades and a road map which will keep NEX E-system adopters more than happy – especially those who have added NEX to their Alpha outfit. Diehard Alpha purists will be less delighted.
At the photokina press conference, a two-year rollout of additional NEX lenses was announced including a fast Carl Zeiss wide-angle, a premium quality G-series standard zoom, a macro lens, a portrait lens, a wide-angle zoom, and a prime telephoto.
Firmware upgrades for NEX-3 and NEX-5 to enable Aperture presetting for video, and AF operation of SAM and SSM Alpha mount lenses with the Sony adaptor, were promised for October with a similar upgrade for the NEX VG-10 in November. The NEX 3 and 5 upgrades will allow assignable functions for the buttons, including direct access to ISO setting or HDR (amongst other choices).
Sony went out of their way – as on their stand – to highlight the explosion of 3rd party adaptors making almost every lens in existence usable with the NEX body’s 18mm register. They announced they were already working with partners to enable production of NEX adaptors and even NEX compatible lenses, but could not reveal anything yet. The opening up of the system to 3rd party makers would, said Toru Katsumoto, help revive photography itself.
With NEX now accounting for half of all mirrorless/compact interchangeable lens sector sales, they were confident of its future.
The bad news, for many, will be that the Alpha 700 replacement – optimistically shown with a vertical grip, 500mm f/4 G SSM lens and a new flash – will have a fixed Translucent mirror just like the A33 and A55. Paul Genge of Sony UK confirmed to us after the presentation that it will not have a flip-up mode to allow shooting without this extra sheet of glass in place.
As tests of the A33 and A55 have shown clearly, the Translucent mirror creates visible bright-edge ghosting or secondary imaging in the vertical direction. For many users, this will be a no-go option; they will look at the Pentax K-5 and the Nikon D7000 and see a ‘pure’ optical path from lens to sensor (although we all know the cover glass assembly of the sensor removes this possibility).
Perhaps the real A700 of tomorrow will be the Sigma SD-1 – the 1.5X factor, beautifully designed, 15 megapixel (true!) Foveon machine claimed as ever to match a much larger real pixel count – 48 megapixels. Well, Sigma need not make such claims. 15 megapixels is enough. It was enough with Bayer pixels. 15 real Foven RGB coincident location pixels will be one amazing camera.
Today was a wonderful day. Summer temperatures. Everyone was sitting round outside in the open spaces at photokina and it was like a big barbecue party with all the wurst-stalls grilling away. The sunniest photokina we’ve ever been to. And there is an amazing level of optimism here about trade and the market. We had a recession – unless someone screws it up, we are in for a boom again. There is so much fantastic stuff coming and China is both the market and the innovator in so many ways.

Additional notes: I filmed the entire conference on my NEX-5, which overheated losing 1 minute midway (pull out the LCD assembly and have the screen away from the body – this stops it overheating so fast, my mistake). But I need my big iMac and fast broadband to edit this and put up several YouTube sections, I can not do so from photokina pressroom or hotel wifi. It will be posted next week.
The image shown of the A7XX (the ‘Advanced Alpha’) is the same mag-alloy body (strap lugs give this away) ‘750’ that was seen at PMA, it’s actually like a slightly rounded Pentax K-5 in size and heft from the description and screen views. Because it will use Translucent mirror technology, you must not assume outright that this means no optical finder. It may use the semi-silvered mirror at 45 degrees, and have a new AF method, quite unlike the A33/A55 – and it could have a really good glass prism finder. But the mirror, like the old Canon Pellix and RT models, would be fixed. We simply do not know but the shape and size indicates it’s not necessarily an SLT in the A33/55 mould. I could devise an AF detector capable of reading from a focus screen (just as the human eye does). Anyone with basic optronics/optics knowledge can see that there are many potential ways to achieve AF, and they do not preclude fitting an optical focusing screen. There are also ways of achieving superior on-sensor contrast detection AF. – DK

Adobe Lens Profile for 16mm f/2.8 NEX

I have made a simple (f/2.8 and f/8 chart set) Adobe Lens Profile for the 16mm f/2.8 NEX E-series pancake lens. It seems to work well for closer distances, because that’s how it had to be made; CA is reasonably well corrected, vignetting is eliminated, and distortion of closer lines – maybe if you are looking through a door frame, etc – is very accurate. The profile was created using NEX-5 and 16mm.
You can get this profile here:

Uncorrected 16mm shot

Using Adobe Camera Raw 6.2 RC with the profile active at default settings
JPEG profile added (17/08/10)
I have now added a JPEG profile from the same set of images as the raw – this is lucky, I didn’t think people would need a JPEG profile but happened to have the camera set to RAW+JPEG when the test shots were made, and this has been requested for those using HDR or other JPEG-only modes.

Using the profiles
A full Adobe Profile is undertaken at several focus distances, apertures and zoom settings (or for prime lenses, just at a range of distances and apertures). The largest chart I can print is A2+ using the Epson 3800, and with a 24mm equivalent lens, this means having the camera surprisingly close to the target. The profile is therefore only 100% correct for subjects at 115cm from the camera, which corresponds to the 4X minimum focus distance suggested by Adobe.
I have found from using the 16mm that its optimum aperture for central sharpness is probably f/5.6, and that chromatic aberration and vignetting do not improve at stops smaller than f/8. There is a slight improvement in detail sharpness in the extreme corners at f/11 and f/16, but this is due to extra depth of field helping to cover a curved focus field. I therefore made test sets at f/2.8 and f/8 for this profile.
The geometric distortion is most visible with closer subjects such as the subject above (The Slave Girl, a bronze c. 1870 by John Bell, at Cragside House in Northumberland). This is a hand-held exposure of 1/4 at f/8, and is perfectly sharp despite the lack of stabilisation; every word of the interpretation can be read at 100%. I have found most shots are perfectly sharp with the 16mm given reasonable care, as you would take with a Leica, to breathe correctly and make a shake-free exposure. This is not the case with SLRs where the mirror action nearly always causes shake.
For more distant subjects, the 100% default setting of the ACR/LR Lens Correction panel can be reduced and where there are few straight lens removed entirely to secure the maximum field of view. Similarly, the vignetting correction can be reduced or removed entirely as the natural darkening towards the corners with this lens is attractive.
Although this profile is named to match perfectly the naming convention used by Adobe for the 18-55mm, I find that ACR 6.2 can not be relied on to use it for Auto as a default (if you work with more than one lens, Adobe Lens Correction soon proves unpredictable in this anyway). If you select Auto, then select Sony, the lens profile will be selected but the Auto button changes to Custom. If you then save new Lens Correction Defaults, or Camera Raw Defaults, ACR will attempt to force this profile on the 18-55mm and the reverse will also happen. So it’s necessary to check which profile is selected. Using ‘Previous Conversion’ for shots taken on the same lens is a quick way to get there.
The additional Manual Controls can be used on top of the profile (the second tab of the interface). The most useful are the geometric distortion (camera angle) corrections. The Chromatic Aberration/Colour Fringe controls can be fine tuned as the correction for CA while very effective relates only to the tested focus distance. CA may change with focus but my particular lens doesn’t seem to suffer from this. All that is necessary is to enable Defringe All edges as a default, and this will remove any hint of colour remaining. As a tip, setting Colour Noise Reduction to a high value can help remove CA and purple fringes in many shots processed through ACR/LR. The colour NR detects 1-2 pixel fringes just the same way it detects individual pixels, and neutralises much as it does noise.

Fitting a Vectis 80-240mm to the NEX

OVER the past few days I’ve been looking at the NEX-5 and a range of lenses and optical systems. I’ve got adaptors for C-mount (16mm/TV/CCTV) lenses, Leica 39mm screw, Minolta MD and the LA-EA1 for Alpha A-mount. The NEX-5 has proved able to provide a surprisingly bright focusing image through a classic German microscope:

It also proved very competent with the Sigma 70-300mm f/4-5.6 OS lens, the adaptor providing power for the OS which is fully functional, and also for auto exposure, leaving only manual magnified focusing to tackle. Continue reading »

Practical's NEX-5 verdict – 8/10

I was going to post this on our Forum for NEX originally. It’s not good form to launch into what may be seen as ‘rival’ publications or journalists, so it’s the kind of thing which is often kept to blog pages or forum discussion. But Practical Photography is one the best-selling, and most powerful, photo magazines in the world.
So, I copied my ramblings and moved them here, instead of putting them in a forum post where just a few hundred people would see them. Tens of thousands of visitors see Photoclubalpha’s main site articles, and I want this to be seen, because it matters.
