The end of Kodak? Shades of Minolta…

Posted on By

Having written this piece tonight, I find myself deciding to put it on Photoclubalpha although it’s not Sony or Minolta related. The websites I run for professionals are seen by very few people, this is seen by 40,000 in a decent month. Therefore, you have a truly diverted article (with pictures taken on Sony and Minolta) – David Kilpatrick

Those who say ‘Kodak is dead’ are reacting a little prematurely. The US Chapter 11 filing for protection from bankruptcy has no equivalent in Britain, and allows time for revenues to be garnered which can save the core of a corporation rather than leave the corpse.

Kodak’s patent battles are not over. While most companies making digital cameras or smartphones have signed royalty agreements accepting that they needed to use patents legitimately, some including their biggest rival Fuji have resisted.

One possibility is that patents – including a portfolio which will bring in substantial earnings for several years to come – will be sold. If a major disputed patent infringer is the buyer, they become the owners of patents which otherwise put a question mark over their balance sheet. As long as a case is in court, any corporation may see its capital value reduced (with its share price) by the amount of the possible liability.

That could make Fuji, Apple or Samsung potential buyers for Kodak. Who has the money to buy Kodak? American, and therefore likely to get permission and support? Apple…

Unfortunately, it does not work the other way round. Pursuing an action for billions does not necessarily convince the market that this is a hidden asset. So while Kodak has aggressively launched several new patent infringement claims in the last few weeks, they had at best a temporary effect on the company’s value, more than matched by reversals.

However, at a time when all stocks have been artificially depressed and the entire market worth a quarter of what was once its stable value, it becomes very difficult to judge the long-term situation. Kodak has a massive theoretical value as a brand, and nearly 5,000 patents still extant from the digital era (the last quarter-century) though all patents do eventually expire. What does not expire is the backdated royalty claim which can be made against a company proven to have infringed patents over a long period.

That’s why Kodak buying some time in Chapter 11 (accompanied by a $950m loan to keep the business running) is significant. If the corporation can avoid being wound up or taken over for long enough to win a patent case, it may rise again. In January, suits were launched against Samsung, Apple and Fuji claiming patent infringement.

Think back twenty years. Honeywell had filed actions against many companies for infringement of their autofocus patents, most settled and added to Honeywell’s revenue stream. Minolta, pioneers of autofocus and makers of the first AF SLR system, allowed the case to go to court instead of settling. Though the Minolta photographic division was to survive 15 more years, the huge award in Honeywell’s favour destroyed their reserves and ultimately was the root of their decline and eventual absorption by Sony. That’s what is at stake with claims like this, the patent owner having the chance to grab a huge chunk of a rival’s assets, capital or future revenues.

Kodak did manage to do things within the digital world, from their 1994 Chinon-based first consumer camera to the demise of the DCS Pro 14 megapixel full-frame Canon and Nikon bodies a little over twenty years later. On the consumer front, they made one of the best bridge cameras – the only one that really matched the Konica Minolta Dimage A2. But the P880 was slow, late, ugly and arrived just when bridge cameras were departing this life.

For partly sentimental reasons, I bought a few Kodak shares in late 2011 when the signs of doom could be seen. Kodak has been worth tens of thousands to me over the last 40 years, helping from my first days as a photographic journalist. It was in Kodak’s London offices we held our editorial meetings in the 1970s, and twenty years later Kodak’s Gold Awards defined the ultimate professional standard. I may win, I may lose on a handful of shares but I have been able to follow their fluctuations daily.

Abandoning the professional

My 40-year ride with Kodak has not been all good. In 1982, I still had a Kodak direct account as a professional photographer and a Kodak rep would call in monthly. From that catalogue we could buy anything from a pack of lens cleaning tissue to a complete 5 x 4″ monorail camera. All kids of studio equipment, darkroom equipment and sundries joined the vital supplies of film, chemicals and paper in the price list. We became customers for such things as Kodatrace graphic arts foil, grey cards and colour targets.

Then Kodak took the first of the great bad decisions; they closed all direct professional photographer accounts. The reasons given in private, by their executives, were that professional photographers were a huge risk – bad and late payers, takers of excessive credit, unreliable and prone to going bankrupt (hmmm…).

I will agree that the 1980s encouraged businesses to hang on each rung of the turnover ladder by their fingertips, with credit costing a fortune in interest rates, and a tax régime which punished the smaller operation. My own business, however well it did, was always struggling to pay tax bills and when you look at the advance cashflow we had to cover, it is no wonder. Our clients in turn struggled to pay us, but we were charging them a sum for one day’s photography which would pay one month’s average wages.

Back then our business was like a salmon fighting upstream through the rapids to the spawning-grounds. Now it’s like a frog sitting on a lilypad and occasionally flicking out a tongue to catch passing flies. Wonder if the same process, quietly, happened to the Big Yellow Box?

Kodak passed their business to trade counters and labs, and took the reps off the road. The trade counters and labs promptly offered rival products alongside Kodak. Within months, we had switched entirely to using Fuji reversal film as their E6 Fujichrome – introduced by our new suppliers – had far superior colours to Ektachrome. The difference was great that in 1983 we were able to open a commercial studio in Nottingham city centre, and grab tens of thousands in business from one long-established rival just because our Fujichrome test shots outshone their Kodak output on the lightbox.

Konica offered us a direct account, and did the same for the local minilab which did much of our machine processing and printing. We bought in Konica for our hand printing, and started using Konica colour negative stock. Then we sealed a deal with the local National Trust region to supply the first film counter dispensers for their shops, and the film supplied was Konica. Ilford Limited, Kodak’s old honourable rival, sourced exactly the same Konica stock and rebranded it as new Ilfocolor and Ilfochrome 100.

Where Kodak discontinued materials, Konica wanted to have more. For many years, Icon’s magazines participated in the annual special order to get infrared film made – something we persuaded Konica to do through PHOTOpro (not the US one, or the current UK magazine, they both nicked our 1989 magazine title).

Kodachrome said fare-thee-well in June, 2009, vanquished by digital media. See that DX coding? Minolta and Kodak worked together on that and Minolta had some of the first cameras with automatically set ISO when you loaded the film. Contrary to many statements, Kodachrome was not especially permanent, undeveloped image life was minimal, processing was highly variable and it didn’t scan well… but photographers still loved it. See baby above. ©DK

From the 1980s on, almost every major Kodak decision was a contraction or a withdrawal when seen from the perspective of a UK photographic business. Kodak film manufacture in Britain ended in 2005 when the last equipment from the Annesley film plant was sold off, but long before this  so many excellent members of the professional division staff, so many activities and ambitions had been curtailed. The loss of the Kodak Gold Awards was a body-blow. The end of the Kodak Wedding and Portrait Awards, a knockout punch. Ultimately, Kodak gave up autonomous distribution even to the trade; it all goes through a distributor (Photologic) before it reaches a trade counter or lab.

Where once, every respectable pro photographic studio or small photo shop was a direct Kodak customer and talked to Kodak daily, photographers are now two or three steps removed. There is no longer a connection and it’s unlikely there will be again.

Photographers still do buy Kodak materials – photographic and inkjet papers alike – and the public buys Kodak printers for their honest approach to ink costs. Plenty of clever and excellent digital cameras are bought every day, and Kodak Express shops occupy small but good positions in busy shopping malls. User-operated printing systems turn digital snaps into Kodak prints.

It is not yet the time to say R.I.P., Kodak but it’s long past the time that the profession said au revoir, Kodak. It does not have to be adieu, yet. Hasta la vista!

Sony’s Zeiss 24mm f/2 Distagon ZA SSM T* reviewed

Posted on By

The Sony Zeiss 24mm f/2 SSM Distagon ZA T* is probably the best, or equal to the best, in its class. It may perhaps be the best ever 84° angle fast lens ever made for the general SLR system market, and I would happy to pitch it against any of the current equivalent offerings for medium format digital.

The initial journey with the 24mm f/2 was not one of intensive companionship – I am long past the stage of getting hold of a wonderful lens and then shoehorning all my photographs into that lens’s view just because I love the glass. I’ve been through that phase. I remember when I was 18 and my then fiancée (Shirley – still here!) bought me a brand new 35mm f/3.5 SMC Takumar, my first ever multicoated lens as well as my first new boxed product. I shot almost everything with that lens for a month…

A full-frame Alpha 900 study at full f/2 aperture. Check the sharpness in the central – very limited – sharp focus zone by clicking the image for a full size version.

My review of the 24mm appears in the British Journal of Photography for January 2012 but was written in November, and at the end I comment that I do not think I would buy one. Well, between writing that and publication – after returning the test lens loaned to me by Paul Genge of Sony UK – I placed my order. I sold a set of lenses including a 28mm f/2 Minolta RS and a 17-35mm Konica Minolta D to pay for it.

Check current availability and price at B&H Photo Video (opens in a new window will not lose this page).

Why?

It was partly medium format which persuaded me. I’ve been experimenting with MF digital, first using a Hasselblad with a Phase One P20 and then shifting to a Mamiya 645 AFII with a 22 megapixel ZD 37 x 49mm back. Once you put the Zeiss on the Alpha 900, the image quality jumps to match the level of a similar MF pixel count. And without spending into the tens of thousands you can’t match the angle of view at a higher pixel count.

These two cameras both shoot 22 megapixels over a 16 x 12″ print shape (the Alpha 900 being cropped) and both were current in 2008 – though the Mamiya ZD model was shortly to disappear. And the two lenses have similar coverage.

I looked at the corners of my MF shots on a 35mm lens (nearly identical angle of view) – to be clean, they demanded f/11. And then I looked at the corners on the Zeiss, which are even cleaner by f/4. Finally, I considered what Sony may have in store – 36 megapixels on full frame. Everything I’ve seen from the 24mm – including its performance on the A77 and A55 – indicates it will not run out of resolution even if full frame goes well over 50 megapixels.

Then I had the job of looking back over the Alpha 900, Alpha 55 and Alpha 77 pictures taken with the 24mm, and preparing some comparison shots. This was when I realised that my normal line-up of zooms, no matter how good, never got the same from any camera – APS-C or full frame – as this CZ prime. It may be bulky, take large filters, and cost nearly £1,000 but no other solution on any format from NEX through A77 to MF offered the same as the 24mm on Alpha 900. You will, however, be surprised later on to see just how well the tiny NEX 16mm f/2.8 does in comparison when both lenses are stopped down to f/8.

The 35mm 2:3 format shape offers a bit of vertical composition ‘rise or fall’ potential compared to to 3:4 shape of my Mamiya with 35mm wide–angle. Beyond this, the 24mm offers both CD and PD focus with different adaptors on the NEX system, and smooth near-silent AF during video on the Alpha 65/77 and future models. It’s both future-proof and a future classic.

Photojournalism or architecture

Because the 24mm has a fast f/2 maximum aperture, it’s seen as a choice for news, documentary, reportage, sports, and close quarters party or family shooting. Though a little vulnerable because of its size, it does this job well. Unlike tele lenses, any mark on the front glass of a wide-angle like this will show in pictures when the aperture is stopped down. Special care should always be taken of retrofocus and fisheye lenses with vulnerable front elements, my own lens will get a Sigma EX DG 72mm UV filter. Why Sigma? I ran a series of ad hoc tests on filters and these turned out to be just as good as Hoya Pro 1 Digital at half the price, and with better multicoating.

At f/2, struggling with light for a hand-held shot with 1/40th at ISO 1600 on the Alpha 55, the 24mm showed surprisingly clean imaging from the boat to the lights on the cliff top.

Here’s a shot taken at f/2.5, 2/3rds of a stop down from wide open – a sensible aperture to give that hint of extra depth of field and improved optical performance. Click the image to view a full size A55 image on pBase.

When fitted to my A55 or A77, the 35mm-equivalent field of view is also a good general lens for photojournalism (what you get is more or less a Fuji X100 equivalent, but hardly pocketable). The performance over the APS-C field of view is so good that working at full aperture carries little penalty at all except restricted depth of field. The geometry and field flatness over the restricted field mean  you could use the lens for artwork copying and get a better result than the 50mm f/1.4 of 30mm f/2.8 SAM macro will produce.

Over full frame, this technical excellence makes the lens attractive to the commercial, industrial and architectural photographer. Whenever you need to apply a strong software correction, focal length figures are thrown out of the window. For example, once the on-board lens correction in the A77 is applied to the 16-50mm f/2.8 SSM lens at 16mm the true minimum focal length equivalent becomes close to 17mm not 16mm.

Hasselblad’s 28mm superwide for its HD series cameras has strong barrel distortion, relying on in-camera and Phocus raw software converter functions to remove it. So while the lens claims to be a 17mm equivalent, that is only true over absolute full-frame 645. On their digital sensors, it’s only equal to a 21mm and the correction means the true crop is more like a 23mm.

A second effect of applying any in-camera or post-process distortion correction is loss of true image pixels. Either you crop the frame after sampling down, or the image is interpolated upwards to fill the frame. Both solutions are far from satisfactory because unlike a fixed interpolation, the value ranges from 0 to whatever maximum is involved (typically between 3% and 7%) and all of this is never a clean ratio.

Above: a sea horizon (the top of the crop is the top of the frame, and it is full width). Top, CZ 16-80mm at 16mm 0n Alpha 77, uncorrected, showing complex wave-form distortion as well as vignetting despite stopping down to f/11. Centre: CZ 24mm on Alpha 900, uncorrected, at f/13. Bottom: 24mm after applying a 2% barrel distortion correction. Click image to view a larger version.

Here the 24mm CZ shines. It really uses all the 24 megapixels of the A900 or indeed the A77, because geometric correction rarely needs to be applied. It has a true 24mm focal length which does not need to be quietly changed to 25mm or 26mm by applying a lens profile. If a 35mm retrofocus AF lens was made for MF digital to this standard, even without the f/2 aperture, it would be hailed as a world-beater. The most that’s needed is a correction of 2% (+, removing barrel distortion) in Adobe Camera Raw and this restores something like a sea horizon near the top of a landscape format frame to a perfect straight line.

No correction is applied here to this full frame 24mm Alpha 900 image – a central horizon, and straight lines which are not parallel to the frame edge, make the 2% distortion (similar to many standard 50mm lenses) no issue at all.

For many subjects, depending on the distance and a ‘rigour’ of the shot (the sea horizon is the most demanding example) no correction at all will be needed. This applies to most interiors, and always to scenes like mountain views or forest landscapes where there is no perfectly flat horizon.

The Alpha 900 is so close to MF digital quality I should really forget the attractions of MF systems. Nearly everything I see from them which impresses me is down to using prime lenses of first quality like the Zeiss and Mamiya 80mm f/2.8 standards and working in a methodical way often using a tripod, minimum ISO, mirror-up operation. Applying the same parameters to Alpha full frame lifts the end result to match – and the CZ 24mm f/2 is a key to unlock that quality.

At f/14, the 24mm is not losing detail sharpness on the Alpha 900 as long as the correct raw processing parameters are applied. To secure this depth of field, f/14 was needed – a medium format camera would require f/27. Holding the camera, viewing and composing this shot were all aided by the ergonomics, weight and viewfinder quality of the Alpha 900. Click image for a full size version on pBase.

This is a dual-purpose or multi-purpose lens. Where the 16mm focal length of the NEX SEL 16mm f/2.8, the Alpha SAL 16-50mm f/2.8, the CZ 16-80mm or SAL 16-105mm all cover the same nominal angle not one of these has the same neutral geometry, even illumination and good corner to corner sharpness at wider apertures. Corrected by software, they don’t have the same true angle and the outer field can become noisy because of extra sensor-mapping gain applied to reduce vignetting.

The size and SEL comparison!

But I would like to show you something surprising. I am a great fan of the 16mm NEX f/2.8 pancake, which is one of the few such lenses made to have a positive (pincushion) simple distortion pattern and a cup not cap shaped field of focus. It is a revolutionary inverted telephoto design of great simplicity, with only 5 elements, enabling the lens to be 16mm focal length yet have a rear node position over 20mm from the sensor – thus avoiding all kinds of vignetting and colour shift problems.

People who don’t understand how to use a focus plane where the corners are focused FURTHER than the centre – the exact opposite of the CZ 24mm f/2 where the corners are focused CLOSER than the centre – do tests like landscapes wide open and wonder why the grass either side of their feet dissolves into blur. Actually all the little 16mm needs is modest stopping down, as would be applied by any professional using a Super Angulon for that matter, to f/8.

First of all, have a look at some lens sizes. I like this shot, as it shows just how big CZ had to make the 24mm to get what they did. It dwarfs the SEL 16mm for NEX and the classic Minolta 28mm f/2 RS:

I’d like you to see the exact comparison between Alpha 900 with 24mm CZ and NEX-5 with SEL 16mm.

This is the A900 and 24mm, entirely uncorrected and uncropped – the building on the right actually does not have a straight wall, don’t be fooled into thinking there’s a sudden burst of barrel distortion! Aperture f/8.

This the NEX with 16mm, corrected in ACR; I’ve tried to keep the camera positions very close but this was real-time shooting and with viewfinder versus screen composition, not so easy. You can see that the 16mm has slightly less true angle of view when corrected but don’t judge from the foreground flower tub, just check the horizontal angle. This is also at f/8.

You can click each image and view a full size JPEG. I have made both of them 24 megapixels, exporting from the NEX to the same size file as the Alpha 900. That may be unfair but you can judge. My opinion is that both the NEX 14 megapixel sensor and the SEL 16mm are underestimated by far too many owners; as far as ISO noise handling goes, the 16mm f/2.8 on NEX is actually as ‘fast’ as the 24mm f/2 on Alpha 900 but that comparison may change with future full frame bodies. As for depth of field, the f/8 shot on APS-C would need to be at f/13 on full frame to match, but in practice both are well covered.

Using the NEX 16mm in different conditions would produce a different result – wide open in a room interior, the corners would be likely to look very blurred. My scene above conforms to the cup-shape focus plane of the NEX lens, and works against the cap-shape focus plane of the CZ 24mm.

Remember as a general rule: barrel distortion = corners focused close than centre. Pincushion distortion = corners focused further away than centre. Moustache or wave form = a doughnut normally of closer focus between centre and corners, but when a full frame lens with this type of distortion (like the 16-35mm CZf/2.8 – or a more extreme example, Canon’s 24-105mm f/4 L) is used on APS-C, you get this doughnut at the corners and more or less have straight barrel distortion not waveform. No distortion at a given distance usually means a flat focus field, the quality which Carl Zeiss highlighted when naming the Planar lens.

Alternatives to the 24mm

The best way to get the 84° coverage with similar near-perfect rendering is to go for the mid-range of a high end zoom. As it happens, Sigma’s 8-16mm is better at 16mm than any of the above-mentioned APS-C options and you can also get a pretty good 16mm from their 10-20mm options and Tamron’s 10-24mm. Tokina’s 11-16mm f/2.8 is weakest at 16mm, best at 11mm. The older Sony 11-18mm is not wonderful at the longer end.

On full format, 24mm at the bottom end of the 24-70mm CZ is no match, it has more distortion and softer corners; 24mm in the middle of the 16-35mm CZ f/2.8’s range is better but with strong complex distortion, more even than the Konica Minolta 17-35mm f/2.8-4 D lens (which manages f/3.2 wide open at 24mm). You might think Sigma’s 12-24mm full frame zoom could be good at 24mm, and perhaps version II HSM when it finally become available for Alpha will prove to be. The original, which I still use mainly for its superb 12mm results, places its worst extreme of field flatness deviation at the image edge when set to 24mm.

I have used Canon’s 24mm f/1.4 USMII and this is faster, larger and more expensive than the Sony CZ lens in almost perfect proportion. Like the CZ f/2 it is a nearly perfect lens, with a hint more barrel distortion and slightly soft extreme corners on full frame wide open. The same goes for the Nikon 24mm f/1.4. I’ve also used Canon’s 24mm TSE tilt-shift and this lens betters the CZ for technical and architectural uses, as it should – so does their 17mm f/4 TSE, which has no match in any format. But such lenses can’t also be used for everyday autofocus image grabbing whether professional or family.

Last question, then. If such a perfect lens can be made at f/2, surely all the affordable 24mm f/2.8 designs could be just as good? We wish! Wouldn’t it be great if the classic Minolta 24mm f/2.8 AF which Sony never transferred to the new Alpha range proved to have the same optical excellence as the CZ? It does not. Nor do the Canon 24mm f/2.8, or the Nikon, or anything made by Pentax or Olympus, or even Leica.

The 24mm f/2 used at f/2.8 on the Alpha 55. Try this with a classic Minolta 24mm f/2.8 and even on APS-C you won’t get the same corner to corner even illumination. Here the focus is on the distance, not the tourists – they are also showing a surprising amount of movement at 1/40th. Click the image for a full size view.

This 24mm is the most recent AF 24mm prime lens to have been designed for full format. Zeiss have designed a slightly more complex manual focus 25mm f/2 Distagon for Cosina partnered manufacture, available for Canon and Nikon, since Sony showed the 24mm at photokina 2010. But Sony’s full-frame DSLR rivals, Canon and Nikon, have not gone for this sub-£1,000 RRP ‘moderately fast’ 24mm niche.

If there’s one competitor, it is Sigma’s excellent 24mm f/1.8 EX DG, which uses a larger 77mm front diameter glass unit to reduce vignetting to the absolute minimum. Distortion is higher, and the lens at present has no HSM version. This makes it less future-proof for Alpha system owners, and also less compatible with NEX and with video shooting in general.

Features of the 24mm

Because it’s a fixed focal length, the 24mm is a very plain lens – it has only two controls and one moving ring. There is an AF/MF switch, though unlike SAM lenses this lens can always be controlled from the body. With SAM type lenses (built in non-supersonic focus motor) it is essential to use only the lens switch, and never to use the body switch instead while leaving the lens set to AF. This is because any attempt to focus manually may damage the gears and motor unless the switch on the lens is specifically disengaged.

Manual focus or held focus can be set or toggled using the single on-lens button. New Alpha models like the 77 allow a wider range of functions to be assigned to the lens button, which is described in the menus as a Focus Hold button. Direct Manual Focus is also supported on bodies which offer DMF, meaning that once focus is confirmed and locked by your pressure on the shutter button, you can fine-tune focus by eye before firing.

The manual focus action is very smooth and well balanced, not too light and not too short in throw (which can be an issue with shorter focal lengths. The focus scale is minimal, behind a traditional Minolta-style clear window, with a depth of field indicator to the minimum f/22 aperture. Really, such markings mean little today as we expect so much from higher resolution sensors. It is time that Sony, and others, built parameter-governed DoF calculation into firmware.

Here, f/5.6 was judged to be fine for the degree of differential focus wanted – at ISO 400, by tungsten kitchen spotlights and window light mixed, on the Alpha 77 hand-held with SteadyShot and manual ‘peaking’ focus.

The CZ design is clearly corrected for medium distance work but retains its performance for close-ups. Unlike Sigma’s design which achieves 1:2.7 image scale, or the new manual Zeiss 25mm which focuses down to 18cm and 1:4, the Alpha lens focuses to 19cm (actually, I make it 18cm as the scale goes beyond the 19cm marking) and manages a 1:3.4 image. Don’t be fooled by distances! The front element of the CZ is already 12.2cm from the sensor plane, and the lens hood takes another 3cm or so. The actual clearance when shooting at close range is minimal. For comparison, the SEL 16mm f/2.8 for NEX will only focus down to 24cm, and the front of this lens is only 40mm from the sensor, leaving a clear 20cm between camera and subject. The Nikon and Canon f/1.4 designs are limited to 25cm and are, quite simply, nothing like as useful for close-ups as the CZ.

You might think that the 16-50mm f/2.8 or the 16-80mm CZ could match the combination of wide angle and close focus found on the 24mm – but not so. To get similar close-ups even at a 24mm setting is not possible – an extra 6 or 7cm in minimum focus distance, when you are talking an 83-84° angle of view, makes a big difference.

Moving in to minimum focus, the bottom wing of the lens hood was only 1cm away from the subject – under 19cm from bread roll to sensor, but only 6.8cm from bread roll to front element. At f/3.2, a hand-held 1/40th was needed (the closer you get, the less you can rely on SS to handle speeds like 1/15th). Focus peaking again enabled the manual focus point to be precisely judged. Great bokeh too.

With a non-rotating front thread, 72mm is one of the classic Minolta sizes. It is necessary to use slimline filters, as with the 20mm f/2.8. It’s interesting to compare the revived older lens with the newer one. The 20mm has only five mount contacts, being non-D specification where the 24mm has eight and reports much more accurate focus data. The 20mm has no lens button, uses screw drive focus, and has a close limit of 25cm at which it has a 1:7.7 image scale. There is also a considerable difference in the build and feel of the CZ; I have no doubt it contains some plastic, but it feels like a good solid piece of engineering and is stated by Sony to have a metal lens barrel. Not metal-skinned plastic, like NEX lenses.

As for coatings, Minolta’s legacy was a use of multiple layer (super achromatic) coatings to rebalance both the contrast and the colour transmission of the entire AF lens range (except designs made by third parties, like the 100-400mm APO). This advantage over other makes was never capitalised on, and made some Minolta designs seem lower in contrast than competitor’s equivalents. No-one ever complained about the colour though! Zeiss’s path from 1975 onwards was to use multicoatings a different way, maximising contrast and light transmission but permitting each lens design to have its own colour transmission quality and variation in contrast. Contax RTS lenses were always praised for their resistance to flare and their extreme macrocontrast.

Since the advent of digital, both overall contrast and colour transmission have become less critical – no need for packs of filters to balance lenses for repro purposes, no need to test Kodachrome with a clip-test to set this up. Just post process or shoot a WB card to taste. Also, Sony Alpha lenses are made in many places – the old Minolta unit, the new CZ-Sony collaboration, co-developed with Tamron and apparently also with Sigma, built by Shanghai Optical or some other owned and partnership facilities in China, made in Thailand but not apparently any more in Malaysia…

While distortion associated with viewpoint and perspective perception is always a companion to shorter focal lengths, over the field of the Alpha 77 (equal to a 35mm lens view or so, in full-frame terms) shapes and solids look natural. At f/4, and ISO 1250, I’ve chosen to downsize this 77 file to 3600 x 2400 pixels (click the image to open). This still allows you to see how clean the light sources in-shot are, with absence of colour fringes. Depending on conditions 1 pixel CA cancelling may be needed with the 24mm.

So, we have here a lens with a Zeiss design and a T* coating which is entirely unlike any Minolta legacy design and will surprise those used to the way ex-Minolta lenses perform. It is fairly immune to flare, not entirely so when confronted with bright sources just outside the image margin, but without the strings of coloured patches associated with 24mms and light sources in the shot. It focuses silently and at a speed which means you may not notice it.

The lens itself weighs 555g, and at 76mm length and 78mm diameter it’s smaller than the 16-50mm f/2.8 SSM which weighs 22g more. I’m not a big fan of lenses you can not clasp in one hand while also operating the lens release mount of a camera; optics this size and weight are about the safe limit. You can not compared the lens-juggling friendliness of the 28mm f/2, for example, with either the 24mm or 16-50mm and even the 16-80mm zoom is much easier to handle in the field. It’s best to remove or fit the hood before changing the lens, don’t leave it in storage position.

The hood reverses over the lens neatly. The whole item, when in this configuration, is a bit large to handle for safe and secure lens changing.

The finish is lustrous, with rubber rib grips that collect dust and dander readily. The supplied lens hood is surprisingly flexible plastic, with a slight spatter finish to the exterior and a kind of semi-flock paint on the inside. It is efficient, but a poor fit with a not very firm bayonet locking action. It’s easy to get the alignment wrong and it’s not as firm or solid as most other Sony hoods. The rear lens cap is still the frustrating one-orientation only design inherited from Minolta, which leaves even those with a quarter of a century of lenscap-fitting experience fumbling for the correct position.

There is of course a Zeiss front lens cap and you get a free blue badge on the lens itself!

Format, pixel count and cropping

For many years when using film I found wide-angle zooms were not essential, standard zooms were useful, and tele zooms were vital. Generally, with any wide-angle you can zoom with your feet or by doing little more than leaning forward or back a bit. Either that or you simply need the widest lens you can get. Whenever I fit my Sigma 8-16mm or 12-24mm on their respective formats it’s the 8mm or 12mm end which is needed. I only end up zooming in if for some reason I decide to leave the lens on, and move to a different situation without time to switch lenses.

With film, you could crop and enlarge. Small pixel count DSLRs made that difficult or impossible – when you are trying to make 6 megapixels do a full page magazine image, cropping is not an option. Zooming in to fill the frame every time became vital from 2000 to 2008 when the first full frame 24 megapixel models arrived.

I think that 24 megapixels has finally made cropping an alternative to zooming. You may need 9 or maybe 12 megapixels, or if you are shooting entirely for the web you may need no more than 2 megapixels. Fixed focal lengths of exceptional quality, sharp all over the frame in the plane of focus, start to be useful. It has never been a good option to crop wide-angle zoom shots asymmetrically, using just one corner. With a lens like the 24mm you can crop any composition out of the high resolution frame and it will not look so different from an on-axis shot with a narrow angle lens.

Lens resolution really does count, as I have found. For three years I used the Alpha 900 with a range of lenses, including the 24-85mm Minolta RS I keep for convenience. When working with medium format lenses on adaptors, I could see that zooms while ‘sharp enough’ usually came nowhere near realising the potential of the 900. Then, using the 24mm, I saw the same pixel-level sharpness pop out. After a month using the 24mm (kindly loaned by Paul Genge) my ordered Alpha 77 finally arrived. I had already seen how the 24mm got the maximum from 16 megapixel APS-C, and this was followed by discovering its power to do the same at 24 megapixel APS-C.

A standard Sony leather-look lens posing pouch is supplied.

How far can this go? If Sony’s 24 megapixel APS-C sensor formed the basis for a full-framer, it would be a 60 megapixel monster and match all but the most expensive medium format image sizes. I believe the 24mm CZ could go there if Sony chose to.

And that, in the end, is why I changed my mind about owning one. The hour or two of useful daylight and howling gales outside have not allowed me to make much use of it yet – but this is a lens for the long term. And for tomorrow’s Alphas as well as today’s.

– David Kilpatrick

Footnote: added February 2016 – I’m now selling this lens, as I don’t think Sony is likely to produce an A99 model II with functions that will restore what I want to have (notably, GPS – they are most likely to drop this). I’m looking at a move to native FE-mount lenses and probably the 25mm f/2 CZ Batis, even though it’s weaker for close-ups, vignetting and distortion.

Here is a recent example of a full aperture shot on the A7RII with LA-EA3 adaptor –

Firmware update for NEX-5, 3, and 3C

Posted on By

Sony has released updated firmware for NEX E-mount cameras, FW v5.0 which updates the bodies to accept the new LA-EA2 Alpha Phase Detect AF lens adaptor. The update works for NEX-3, NEX-5, NEX-C3, NEX-VG10 and the professional video Sony NEX-FS100U.

Prior to this firmware update, the LA-EA2 only worked with the NEX-5N , NEX-7 and NEX-VG20. With the LA-EA2, a micromotor driven Phase Detect AF system is built-in, which allows the camera to focus with all A-mount AF lenses.

Key points of the new firmware update include Micro AF adjustment, when using this adaptor, for M-AF/SAL/SAM lenses, and the ability to assign AF points on the 15-point module, from the screen display.

Tamron 18-200mm VC for NEX

Posted on By

Tamron’s has announced a high-power zoom for Sony’s NEX-series – the 18-200mm F/3.5-6.3 Di III VC (Model B011).

The image-stabilised lens has exactly the same nominal specifications as Sony’s own zoom. The angle of view is 27-300mm when converted to 35mm format.

It weighs 460g, uses 62mm filters, and has VC (Vibration Compensation). The metallic lens barrel exterior is available in two colors: black and silver. A newly constructed stepping motor allows contrast-detection AF during video shooting. Direct Manual Focus (DMF) allows the user to make fine manual adjustments in the AF focus.

Di III (Digitally integrated design): A new designation Tamron gives to lenses engineered specifically for mirrorless interchangeable-lens cameras with no internal mirror box or pentaprism, adopting an optical design that matches the characteristics of the digital camera.

The result of this development is a lens that is compact and lightweight, featuring a 62mm filter diameter and weighing only 460g. The lens is available in silver and in black.

Tamron’s VC mechanism employs a three-coil system, electromagnetically moving the VC group via three steel balls. The VC lens elements are held in place only by contact with the steel balls, achieving smooth movement with little friction. This provides a stable viewfinder image with excellent tracking performance that eliminates the blur from handheld shots for cleaner, crisper shots.

Tamron’s earlier VC unit has a moving magnet system with heavy magnets in the vibration-compensating lens. However, the new VC mechanism adopts a lightweight moving coil system that reduces the load on the drive system. This allows the drive to be operated with smaller coils and magnets, reducing the weight and size for the entire VC unit. In addition, improvements to software and other elements of the VC mechanism used in the 18-200mm Di III VC have made the mechanism even quieter.

Specifications 18-200mm F/3.5-6.3 Di lll VC (Model B011)

  • Focal length: 18-200mm
  • Maximum aperture: F/3.5-6.3
  • Angle of view3: (diagonal) 76˚ 10´-8˚ 03´
  • (Horizontal) 66˚ 16´-6˚ 43´
  • (Vertical) 46˚ 51´-4˚ 27´
  • Lens construction: 17 elements in 13 groups
  • Minimum focus distance: 0.5m (throughout zoom range)
  • Maximum magnification ratio: 1:3.7 (at f=200mm: MFD 0.5m)
  • Filter size: φ62mm
  • Length4: 96.7mm
  • Entire Length5: 102.0mm
  • Diameter: φ68mm
  • Weight: 460 g
  • No. of diaphragm blades: 7
  • Minimum aperture: F/22 – 40
  • Standard accessories: Flower-shaped lens hood (included)
  • Compatible mounts: Sony E-mount

The angle of view of the lens when used for video on the Sony digital HD video camera recorder NEX-VG10 is 32.4 – 360mm when converted to the 35mm format.

Due to an inherent characteristic of this TAMRON lens, the resulting image in the LCD monitor may be displayed in a “pumping” manner in the continuous operation of the focus search function when using the Sports Action mode on Scene Selection. The actual images captured will NOT be affected by this circumstance. In other Shoot Modes (P, A, S, M), when the focus mode is set to Continuous AF (AF-C), the same condition may also arise. The actual images captured will also NOT be affected by this circumstance.

As an alternative to the above settings, you can change the focus mode to Single-shot AF (AF-S) or Direct Manual Focus (DMF).

This lens was developed, manufactured and will be sold based on the specifications for the E-mount that was disclosed by Sony Corporation under Tamron’s license agreement with Sony Corporation

Price: The suggested retail price is yet to be announced. Availability: Early 2012. Exact date to be announced.

Sony Alpha 77 & 65 Firmware v1.04 download

Posted on By

The download is approximately 65MB of data in a Mac .dmg mountable disk image, or some other stuff for Windows.

The process will take about seven to ten minutes overall including downloading, opening and completing the procedure. You need a battery for the camera with at least three bars showing – preferably fully charged – and your computer to camera USB cable. The actual transfer to the camera takes about four minutes follow by 30 seconds of internal processing.

During the Mac update, you may see this window when the camera is turned off for the upload from computer to camera, and at the end of the process:

Do not worry about this – it refers only to the Mass Storage connection. Do not let this distraction interrupt your process.

SLT-A77V Firmware Upgrade v1.04

Windows
http://www.sony-asia.com/support/download/478891

Apple Macintosh
http://www.sony-asia.com/support/download/478893

Features:
Adds auto-correction of JPEGs for two lenses:
Vario-Sonnar T * DT 16-80mm F3.5-4.5 ZA (SAL1680Z)
Sony DT 16-105mm F3.5-5.6 (SAL16105)
Improved ‘usability’ – remains to be discovered what that means
Improved image quality (presumed to be JPEG quality and noise levels)
Faster command/menu/setting response (less time lag between control wheel and updated screen info)

Example: correcting the 16-80mm CZ lens wide open at 16mm – focused on an A2 target, a very close distance which exaggerates the distortion level of the lens:

Above: uncorrected image

Above: in-camera correction. For full size versions which allow you to examine the CA (very prominent at f/3.5) and the degree to which it is corrected in the Fine JPEG, click the images. As you can see the image is enlarged by correction, so not quite as much coverage is achieved. But it’s less than you imagine; a fully corrected 16mm shot ends up being similar to a 16.35mm lens on the vertical and horizonal axes, or a 16.55mm lens on the diagonal. That’s still wider than a rectilinear perfect 17mm, so it’s better to use a bendy 16mm than lay out for a Zeiss MF 18mm, if you want coverage. And even Zeiss 18mms show some curvature.

We’ve tested the 16-50mm as well and BOY does that lens distort at 16mm – far worse than the CZ – which makes it clear that the in-camera lens correction goes hand in hand with this lens. To get any kind of straight line image, it’s going to be necessary to use the correction or a profile for raw conversion in a program like Adobe Camera Raw which accepts lens profiles.

The responsiveness of control wheels changing settings is greatly improved – altering +/- EV compensation for example now responds almost in real time as you shift the control. No significant improvement can be detected so far in image quality despite the claims, at least with the 100 or so test shots we’ve taken at different ISOs using a Color Checker, and other spot checks for Low/Normal/High NR. But there are so many modes on the A77 including panoramas, multishot, DRO, that the improvement may well be specific functions which Sony will explain in more detail.

Free download PDF guide to Adobe Camera Raw

Posted on By

You can open or download an excellent (slightly dated, unrevised since ACR 6.1 but finally translated into English from the original Italian by Francesco Marzoli) guide to all the deeper functions and tricks of efficient workflow using Adobe Bridge, Camera Raw, Lightroom and Photoshop from X-Rite:

http://www.xritephoto.com/Documents/Literature/EN/GuidaCameraRaw_en.pdf

This PDF instruction book obviously mentions the use of X-Rite’s ColorChecker Passport for calibrating cameras, that’s why they have sponsored the guide. But it goes far beyond this to explain with clarity all the controls of ACR, and many tips are given on how to use them best.

As an example, we didn’t know that Bridge could be forced to use Camera Raw without taking over Photoshop – meaning it can be run separately, allowing you to do other work in Photoshop while ACR does file conversion and saving from within Bridge alone.

You can load this guide into your iPad or other reading device. Just SAVE the target file, and ADD to your iTunes Bookstore Library, it will then be readable. For other devices simply save the PDF and transfer.

Channel Islands VAT dodge to end in 2012

Posted on By

The story below may not seem very important to photographers, but actually, it affects suppliers including 7DayShop, MyMemory, and indeed all the digital and photo processing companies who have used the Channel Islands VAT loopholes.

—————————————————-

The group of retailers campaigning against an industrial-scale offshore VAT avoidance scheme that has destroyed scores of viable, job-creating businesses and cost the UK taxpayer over a billion pounds, is winding down its campaign, having accomplished its mission.

From the 1st of April 2012, Low Value Consignment Relief (LVCR) will no longer be applicable to Channel Island goods entering the UK. LVCR – the exemption from VAT of goods valued below £18 (now £15) originating outside of the EU – had started life in 1983 as an innocuous administrative measure to relieve governments from the expense of collecting incidental amounts of VAT. But from the late 90s it mushroomed into a huge VAT avoidance ruse. Major retailers deliberately circulated UK goods via the Channel Islands – which happen to be outside of the EU for tax purposes – in order to take advantage of the import relief.

The result was a huge competitive distortion, creating a market where the major, even sole, determinant of success became not quality or customer service but ability to route via the Channel Islands and avoid tax.

The exploitation of LVCR also saw the rise of giant online retailers including Play.com and theHut, leading to the demise of UK high street chains like Zavvi and Fopp, but the storm hit the online sector in the UK the hardest.

RAVAS founder Richard Allen explained: “By 2010 there were no online retailers of CDs left on the mainland. Some of the high-street guys could survive because they offered an in-store experience that the offshore websites didn’t, but purely online folk like me who had to pay VAT didn’t have a prayer.”

The impetus for RAVAS began in 2005 when online retailer Mr Allen became concerned at the impact of the abuse of LVCR on his specialist mail order music company, which had been very successful up to that point. By 2006, with the move of HMV’s online operation to Guernsey to compete with Play.com, it became apparent that the level of LVCR use was about to escalate. By 2007 only VAT avoiding businesses could compete in online music retail.

Having been forced, like many other UK music retailers, to close his business and lay off UK staff, Allen began a campaign to end the abuse of LVCR. With help from the Forum of Private Business, including its former Brussels representative Martin Smith, Mr Allen submitted a complaint to the European Commission, focusing on wording in the original LVCR Directive showing that member states had a duty to crack down on avoidance or abuse resulting from LVCR. He was supported by retailers from many different sectors affected by LVCR abuse, including horticulture, cosmetics, computer peripherals, and gifts.

The website www.vatloophole.co.uk became a focus for the group, who eventually managed to make the EU and the new coalition Government realise the true scale of the abuse of LVCR in The Channel Islands. Whilst the Labour administration had completely ignored his campaign, George Osborne responded sympathetically to Mr Allen’s case.

In the UK Budget for 2011 Osborne announced that the government would work with the European Commission to find a way to halt the abuse of LVCR via the Channel Islands. The final instalment of these measures is the complete removal of LVCR from all goods entering the UK from the Channel Islands as of the 1st of April 2012.

Richard Allen said: “When we first initiated the complaint the odds were not exactly stacked in our favour. Many of the people affected had already gone out of business and so we were not a strong voice. We had no money to put into hiring expensive consultants or lawyers, but we argued our case directly with the conviction that we were in the right.

“After four years of communication with the commission, the submission of large amounts of factual data on the ongoing LVCR trade and a meeting with officials, the EU finally ruled that this practice was an abuse of the relief and a barrier to trade. We understand that the Commission has had lengthy discussions with the UK Government to put in place legal measures to prevent the abuse. Whilst it took a long time and huge amount of work the success of RAVAS is living proof not only that the EU complaints system works, but also that anybody can overcome the odds and overturn an injustice if they have a fundamentally sound case and the persistence to argue it thoroughly. ”

Mr Allen and Mr Smith are now encouraging any individuals or businesses affected by faulty policy or anti-competitive behaviour to get in touch and share in the secrets of their success.

Phil McCabe, Senior Policy Adviser at the Forum of Private Business, said: “This VAT loophole has been routinely abused by most of the UK’s large retailers for far too long and the Government’s decision to finally end it is good news for the vast majority of small traders across the UK.

“Allowing these large companies to have a significant price advantage on a range of goods for decades has caused a great deal of damage to high street shops and small online outlets. Many have closed – but others that are left have now been a fighting chance.

“An industry owing its existence to a tax avoidance scheme that is anti-competitive and classed as tax abuse under EU law because it is being exploited for reasons utterly different from its original purpose as an administrative relief, is simply unsustainable. Good riddance to it.

“RAVAS should be applauded for its continued courage, commitment and determination in bringing this damaging trade to an end, particularly by taking the complaint to the EU.”

Canon kyboshes the competition – full cinema system

Posted on By

Canon has launched, out of the blue as far as we were concerned, a complete fully featured Cinema HD production system including full-frame digital video camcorder and EF-fit lenses designed to compete head-on with the top offerings from Zeiss/Arri and Red.

The Cinema EOS system also competes with Sony right in the heart of Sony prime territory. It looks like nothing so much as an acknowledgement that Sony has attacked Canon’s primary still imaging market effectively, and Canon, instead of competing in that arena, has decided to hit their rival where it really hurts. Their announcement feels like ‘right, we’ll show them – this will be the best HD movie production system in the world’.

Porn film makers will be rubbing their hands with glee – or something, not sure if you call it glee…

At the heart of this is optical excellence. They have created a 4K (the higher resolution than 1080p HD, full large screen cinema format) lens system. Imagine these – they come in the ciné PL mount, but also in the full frame EF camera mount. You could use these on a regular Canon. And they will not have the shortcomings of lenses such as the 24-105mm f/4 L – these will be better than CZ quality if Canon is to secure a market share.

CN-E 14.5-60mm f/2.6 L S (Super-35 or APS-C is what the S stands for, like EF-S)

CN-E 30-300mm f/2.95-3.7 L S

CN-E 24mm f/1.5 L F (the F stands for Full Frame)

CN-E 50mm f/1.3 L F

CN-E 85mm f/1.3 L F

Look at those apertures – they are like Angenieux apertures! Bet you they are also true T-stop figures. Here’s their wording:

Wide-Angle and Telephoto Cinema Zoom Lenses for EF and PL Mounts
CN-E14.5–60mm T2.6 L S / CN-E14.5–60mm T2.6 L SP
CN-E30–300mm T2.95–3.7 L S / CN-E30–300mm T2.95–3.7 L SP

The four new Canon zoom cinema lenses comprise the CN-E14.5–60mm T2.6 L S (for EF mounts) and CN-E14.5–60mm T2.6 L SP (for PL mounts) wide-angle cinema zoom lenses, and the CN-E30–300mm T2.95–3.7 L S (for EF mounts) and CN-E30–300mm T2.95–3.7 L SP (for PL mounts) telephoto cinema zoom lenses. Each lens supports 4K (4096 x 2160 pixels) resolution, which delivers a pixel count four times that of Full HD (1920 x 1080 pixels), and offers compatibility with industry-standard Super 35 mm-equivalent cameras as well as APS-C cameras (Not compatible with 35mm full-frame or APS-H camera sensors).

Employing anomalous dispersion glass, effective in eliminating chromatic aberration, and large-diameter aspherical lenses, the zoom lenses achieve high-resolution imaging from the centre of the frame to the outer edges. Each lens is equipped with a newly designed 11-blade aperture diaphragm for soft, attractive blur characteristics, making them ideally suited for cinematographic applications.

The focal length range of 14.5–300 mm covered by the new zoom lenses represents the most frequently used focal lengths in theatrical motion picture production, a range that often requires a combination of three or more separate zoom lenses. Canon’s new wide-angle and telephoto cinema zoom lenses, however, offer a wider angle and powerful zooming to provide complete coverage across this range with just two lenses. The new wide-angle cinema zoom lenses will offer the industry’s widest angle of view among 35 mm digital cinema lenses with a wide-angle-end focal length of 14.5 mm (as of November 3rd 2011, according to published competitive data).

Zoom, focus and iris markings are all engraved on angled surfaces for improved readability from behind the camera. With a focus rotation angle of approximately 300 degrees and a zoom rotation angle of approximately 160 degrees, the lenses facilitate precise focusing performance while making possible smooth and subtle zoom operation.

The new top-end cinema zoom lens line-up can be used with standard manual and electronic movie industry accessories, as well as matte boxes. Featuring a unified front lens diameter and uniform gear positions, the lenses do away with the need to adjust or reposition accessory gear when switching between other lenses in the series.

Single-Focal-Length Cinema Lenses for EF Mounts
CN-E24mm T1.5 L F / CN-E50mm T1.3 L F / CN-E85mm T1.3 L F

Like their wide-angle and telephoto cinema zoom lens co-stars, Canon’s new CN-E24mm T1.5 L F, CN-E50mm T1.3 L F and CN-E85mm T1.3 L F cinema lenses deliver 4K optical performance. The three lenses, designed for use with EF mounts, are compatible with not only industry-standard Super 35 mm-equivalent cameras, but also 35 mm full-frame, APS-H and APS-C sensor sizes. The trio incorporates anomalous dispersion glass and large-diameter aspherical lenses for high resolution imaging throughout the frame, and features a newly designed 11-blade aperture diaphragm for gentle, attractive blurring.

With focus and iris markings that are easily visible from behind the camera, Canon’s three new fixed-focal-length lenses support convenient film-style operation and, offering a focus rotation angle of approximately 300 degrees, facilitate precise focusing performance.

The CN-E24mm T1.5 L F, CN-E50mm T1.3 L F and CN-E85mm T1.3 L F support standard manual and electronic industry accessories and matte boxes, and have a unified front lens diameter and uniform gear positions, eliminating the need for adjustments when switching lenses.

Costs

Is there a snag? Maybe. The cheapest of the prime lenses will be over £4000/$6,300 and the zooms will cost a cool… $47,000 each. That is not a misprint. That is not even my income. But it shows you how big the stakes are in movie making gear PROPER.

The movie camcorder

Then there’s the camera to go with them – the EOS C300/C300PL interchangeable lens digital video camcorder. It may only have an 8.29 megapixel Super-35mm CMOS sensor. It’s only 1080p but it claims to read coincident or complete RGB pixels for each pixel location, using 4:2:2 sampling, and to record at 50 Mbps (almost twice the data rate of the best DSLR video). It has twin CF card slots. It has many other features including things like metadata coding for better identification of lenses in edit work, and the capacity to be controlled remotely from an iPad or iPhone (with accessory WFT-E6B wireless transmitter).

A new DSLR

Canon is developing a new-concept EOS-series digital single-lens reflex (SLR) camera. Incorporating an enhanced version of the video-capture capability offered in the current EOS-series line-up, the new camera will be ideally suited for cinematographic and other digital high-resolution production applications. The model will be equipped with a 35 mm full-frame CMOS sensor and, enabling the recording of 4K video* (at a frame rate of 24P, with Motion-JPEG compression), will make possible the type of exceptional image quality and sublime imaging expression to be expected from the next generation of “EOS Movies.”

So why have I posted this on Photoclubalpha? Easy. I was still up and around at 1am when the news had come in by email. And it matters, because Sony will react to this. Canon has just moved in on their home territory, where they were already getting a foothold through EOS-movies and existing Canon video offerings, in a much bigger way. This could be the best thing Alpha owners could see happen because it will force Sony to update their lens range quickly and to improve the overall offering their DSLR division makes to their camcorder division (via adaptors).

Image Data Converter v4 – download now

Posted on By

Sony’s Image Data Converter latest version – 4.0 – will handle all Alpha raw files from A100 to A77, and all NEX raw files. It offers improvements in performance and stability, but it also eliminates the need for the Lightbox application (found in v3) as a separate item. You simply browse for a folder of images, and IDC now shows a regular thumbnail browser with image information not unlike Adobe Bridge.

Double-clicking the thumb opens the image as expected in the raw editor. This has all the features of v3 are a bit more, but at least on a latest MacBook Pro with 2GB memory it seemed to crash and quit (normally after processing the file) rather too often.

One new feature, found when you save the file and not in the main processing controls, is a crop with Inclination Control and a grid:

Testing Alpha 77 raw files on the new software, the Bayer conversion seemed to be incredibly noisy and the noise reduction left fine detail heavily smeared much the same as for in-camera JPEGs, but the colour styles, DRO settings and some other aspects read from camera EXIF data are retained. It can not be recommended as a main choice for raw conversion, and certainly not for high ISO images, but it’s available and is a fairly small application to install on laptops or less powerful machines.
