The final release of Adobe Camera Raw 6.2, DNG Converter 6.2 and Lightroom 3.2 includes raw conversion support for the Alpha 33 and 55 models as well as the NEX-5 and NEX-3, Alpha 290 and 390 which were included in the Release Candidate versions. These August 30th releases are final version, RC versions are a form of beta test.
The bad news is that anyone using the LR3.2 RC as a temporary free solution for getting full profile correction without investing in Photoshop CS5 will lose their freebie. But Lightroom is eminently affordable, and it can function as a raw conversion front-end for any earlier Photoshop or Elements version. On its own, it is a mere 10MB of program data fatter than Adobe Camera Raw as a plug-in and runs with great efficiency on modestly specified laptops (etc). It’s a lean, keenly priced solution which offers many further benefits as a DAM (Digital Asset Management) library such as keywording, copyright control, metadata editing, version stacking and multiple catalogues.
I am informed that support is included for the 16mm lens on NEX (profile) but I can’t tell whether it is the profile I supplied to Adobe Labs, or a new one, because my profile has remained unchanged on my system – same names, same modification date. And there’s no NEX-3 version which might be expected if they had created new profiles. So it looks as if it could be worth sending profiles into Adobe after creating them.
It’s fantastic news that Adobe has released ACR for the new Alpha 55 16 megapixel sensor before the cameras even hits the street – mine is on order, waiting! Not so great for Nikon users; no D3100 raw conversion in this release. But Canon users get the 60D (despite Adobe missing it out from their front page list). Adobe did this Sony friendly pre-release once before, for the Alpha 100, getting the conversion into place before the camera went on sale.
The bad news is that the Alpha 580 and 560 models are not in the list alongside the fixed mirror pellucid, transflective (anything but Translucent, please…) cameras.
is already on-line and shows a March 2010 publication date, which means that Sony has had these new cameras in existence since the beginning of the year, certainly well before PMA when mockups were shown. It’s likely that Adobe’s Thomas Knoll has been using one from the first bug-free pre-production model onwards!
Now all we need is the revised lens series with SAM or SSM motors fitted into the 16-80mm CZ, 16-105mm Sony, 18-200mm and 18-250mm Sony; the 11-18mm wideangle replacement, the 75-300mm SAL replacement, and a few other goodies. Hopefully all Zeiss glass gets SSM where possible. That 16-80mm CZ is four years old now as a design. A tweak to the maximum aperture, or the zoom range, would revive interest.
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.

Although it’s far from a perfect lens, this small 1999 Minolta RS optic is my favourite for general travel and everyday use on the Alpha 900. It is a convenient size and weight, performs well when stopped down a little, and has exactly the range and minimum focus I need.
Mouseover image to see effect of this profile used on a shot taken at 70mm focal length.
The profile created for ACR6/LR3 is at four focal lengths – 24, 35, 55, 85 – and two apertures, wide open and f/9. The chart distance ranges from about 120cm to about 4m.
Right click and save. Correction of CA and distortion is pretty good, and this profile identifies itself correctly as a Minolta lens. It should be placed in the Sony directory of Adobe Application Support>Camera Raw>Lens Profiles.
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.
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.
HDR shot opened in Camera Raw without adjustments, but with the Profile enabled
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.
Adobe has announced the Lightroom 3.2 and Camera Raw 6.2 Release Candidates, available for immediate download on Adobe Labs. The updates extend raw file support to 12 new popular camera models including the Sony NEX-3 and NEX-5, Alpha 290 and 390; improve on several of the lens correction profiles introduced as part of the Lightroom 3 and Camera Raw 6.1 releases; and add over 50 new lens profiles to help photographers automatically correct for undesirable distortion and aberration effects.
But they let Sony down in a big way by only including the 18-55mm OSS lens for NEX, omitting the 16mm which must be very simple to profile (after all folks, there are only TWO officially available lenses for NEX right now – you found time to profile no fewer than 15 lenses for the Pentax AF645, for the benefit of all two dozen worldwide users of this outstandingly popular digital option…)
In addition, the Lightroom 3.2 Release Candidate now allows Lightroom 3 customers the ability to publish their photos directly to Facebook from within the application, and addresses issues reported by customers on the Lightroom 3.0 release. Adobe continues to encourage the community to provide feedback on the updates so it can ensure the highest quality experience for customers working on a variety of hardware and software configurations.
Pricing and Availability
The Lightroom 3.2 Release Candidate is available as a free download for Lightroom 3 customers, and the Photoshop Camera Raw 6.2 Release Candidate is available as a free download for Photoshop CS5 customers.

Newly Supported Camera Models
Panasonic DMC-FZ100, Panasonic DMC-FZ40 (FZ45), Panasonic DMC-LX5, Pentax 645D, Samsung NX10, Samsung TL500 (EX1), Sony A290, Sony A390, Sony Alpha NEX-3, Sony Alpha NEX-5
Also, this update improves the colour and noise profiles for the following cameras that utilise the DNG raw file format already supported in previous versions of Lightroom and Camera Raw: Casio EXILIM EX-FH100 (DNG) and Leica S2 (DNG).
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.
TAMRON Europe GmbH, Cologne, Germany attains drastic 2 Mio € penalty verdict against Ruitenberg / Crown in the Netherlands for dealing with illegal imports (press release)
On June 30th 2010 the district court in Utrecht/Netherlands (file reference number 262876/HA ZA 09-458) rendered a verdict against Mr. H.P. Ruitenberg and 4 respective entities of the so-called Crown group in favour of Tamron Europe, Cologne, Germany.
After an extremely harsh and meticulous prosecution Tamron Europe`s lawyers succeeded in providing evidence that Mr Ruitenberg and several of his respective Crown companies violated the trademark rights of Tamron by dealing with illegally imported merchandise, which was not imported into the EU by or on behalf of Tamron. The court could be successfully convinced of the damaging impact to Tamron Europe`s business resulting from the illegal trade.
The verdict includes a penalty of €2,000,000 for non-compliance with an earlier verdict that Tamron obtained in its favour. Tamron Europe urgently suggests all retailers in Europe to purchase Tamron merchandise solely from unsuspicious and fully reliable sources, as the company will not hesitate to take similar drastic legal action against any kind of trade with illegally imported Tamron products.
Sony is expanding its line-up of over 30 A-mount lenses with new models that will appeal to seasoned photographers and those new to DSLR cameras alike – a 35mm f/1.8 DT (APS-C) SAM, an 85mm f/2.8 full frame SAM, and the long-awaited 24mm f/2 Carl Zeiss Distagon T* 24mm f/2 for full frame with SSM ultrasonic focusing. In the interests of getting this report on line, it’s mainly Sony words, with a few added comments and edits.
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.
