Photoclub Alpha

Sony has released - without announcement - a new firmware version for the Alpha 700 which includes an OFF function for high ISO. This is presumed to be in advance of tomorrow’s press conference, where the Alpha 900 will be revealed. Journalists could be expected to ask questions about the NR, and the lack of firmware upgrades to the Alpha 700, and they have acted just in time for this launch and photokina to remedy the situation.

This article was originally published in Photoworld magazine April 2008. It discusses the reasons for choosing between the 18-70mm, 16-105mm, 16-80mm, 18-200mm and 18-250mm kit lens choices for the Sony Alpha DSLR system and has been updated from the original text.

Following announcements that Sony has developed a backlight technique to enable extremely low noise exposures, we receive this press release which may or may not be related - a Sony CCD astrophotography camera capable of one-hour exposures and programmed sequences. Resolution seems a bit basic though.

Here’s a question which came in to my email just now:

“Could I process a RAW file in Photoshop to achieve a similar effect as if I had used a Polaroid lens filter?
Or would I be better just using the Polaroid filter?”

The answer is that you can never imitate the effect of polarizing light (which changes the way reflective surfaces look, and deepens or lightens the sky blue according to the zone of the sky relative to the sun’s position. But you can use Adobe Camera Raw (CS3 versions) to deepen skies you never thought could be rescued.

The introduction of a £399 (street price, RRP £449) DSLR with 14.2 megapixels – with or without a useful type of Live View – should have been applauded by reviewers. It’s the single most important point about the camera. No other DSLR approaches this image size and resolution at such a low price.

Now that there are five Sony Alpha DSLR bodies in circulation, with many owners of the original 2006 Alpha 100 considering a replacement, the differences between this ur-Alpha and the 2007-8 generation of Alpha 700, 200, 300 and 350 need examining.

Apple’s Aperture 2.0 is a tedious program to test, with all its creation of ‘projects’ and ‘libraries’, ‘albums’, ‘vaults’ and nonstandard GUI, and it isn’t fast in processing files or passing them to Photoshop (which it does in 16-bit form, just another step to reverse before saving as far as I’m concerned). However, it’s handling Alpha 700 raw quite well. And it does things differently, with non-destructive raw editing, stacks of image versions, and so on.

Sony say that the Alpha 100 has a 230,000 pixel rear screen and the Alpha 700 has 920,000 pixels. What they don’t make entirely clear is how many individual R, G or B pixels are used to create each ‘pixel’ of the image (complete RGB). In fact the 920,000 pixel screen is VGA - 640 x 480 - in display resolution, which is 307,000 pixels not 920,000. What is going on? We took some macro images to show you.

SINCE September 2007 I have had for test the Canon EOS 40D, Sony Alpha 700, Nikon D300, Olympus E-3 and Nikon D3 in that order. The reports have been published in the British Journal of Photography, and later on in Master Photo Digital and f2 magazines (some are yet to appear, in February, in these titles). My own system is Sony Alpha but I have to be as objective as possible when field testing all makes. I also have to seek out the unique selling points, the reasons for owning any given model, rather than just compare them on a tick-chart feature basis.

With the Alpha 200 about to appear, I guess it’s time to sum up what I think about the Sony Alpha 700 and how it compares to the competition.

After reading Andrea Nivini’s article in Italian Tutti Fotografi, December 2007, which launches an attack on Adobe’s Camera Raw plug-in and its handling of many camera types - but specifically, the Sony Alpha 700 - I decided to check out whether the December 5th release, ACR 4.3.1, fixed the problems.

I HAVE set up a pBase gallery with a large number of comparison studio shots, all the way from ISO 100 to the maximum, using the A700 and Nikon D300. It has some minor discrepancies in shooting conditions which I need to explain to anyone visiting the gallery.

ON OCTOBER 10th I left the UK London press launch complete with an Alpha 700 review camera. I’ll be covering the many aspects of the Alpha 700 performance in later reviews, but this camera is so good I wanted to get just something out to you right the next day.

THE ALPHA 700 cameras tried in Italy by press representatives, including Paul Olsen of Dinside Data in Norway who sent us the raw and JPEG files for the image used here, may or may not have been pre-production samples. Some cameras which were felt to be poor had over 1,000 exposures recorded before the event. Olsen’s camera appears to have been new, recording frame counts in the 40s during his shoot, and may be a final production sample rather than one of the much-used demo bodies.

IT IS very difficult to find a good JPEG from the Alpha 700 pre-production model tests shot in Italy, because too few cameras were available for too short a time - and many of the journalists present were not photographers. But we have found one image you will love.

THE question is being asked, will the Alpha 700 match the rich colour rendering of the Konica Minolta 7D and 5D? These cameras had identical colour profiles, and were in turn very similar to the Dimage A1 and A2. The Sony Alpha 100 proved very different. Here’s my best attempt to explain why.

PRODUCT shots of the Sony Alpha 700 have been released, and are shown here to our standard web page size of 600 pixels or smaller.

TEMPORARY website pages on the afternoon (GMT) of September 5th managed to leak the entire specification sheet and several new PR images of the advanced amateur Alpha model, along with its name - the Alpha 700. You wouldn’t pick a wife or husband on the basis of their on-paper specification, so remember, the only way to partner up with a DSLR and be happy is to try it in your hands first.

FUJIO NISHIDA, President of Sony Europe, speaking at the Berlin IFA consumer electronics and technology show on August 30th, mentioned the Alpha system alongside Cyber-shot digital still cameras and Handycam digital video as part of Sony’s plan to introduce HD (High Definition Television) formats throughout. He held up the new ‘smile shoot’ Cyber-shot T200 with its ability to output playback of images in 16:9 format directly to Sony Bravia LCD TVs.

THE PRESS and trade announcement made below on August 20th 2007 does little to confirm on deny rumours about the forthcoming AA and Flagship DSLRs. Why? You need to study the image, and study the dimension data, and fully understand what they are talking about, before the implications are clear.

IN 1998 Minolta published, for their 70th anniversary, a large poster featuring all the landmark cameras from their own museum and employee collections. Many of the cameras shown - all fairly small on the poster - were well used and worn examples. The original image-files for the poster, which we have archived, are of poor quality. They are Japanese inkset CMYK sharpened for pre-press, with very dark gamma. This page re-creates all the information from the original poster, complete with the photographs.

THE appearance of press-release resolution (14Mb) images of the new Alpha - un-named but thought to be the Alpha 200 or 300 because of the product code earlier assigned to shots of prototypes at PMA - combines with reports on various forums from European Sony executives visiting Japan to suggest that the launch announcement for the new model and a range of full-frame lenses is imminent.

THE PROBLEM of darkened extreme corners with the 16-80mm CZ Sony lens definitely exists. They are there in many of my shots, with or without SSS anti-shake enabled, significant softly darkened corners. Everyone is saying this must be due to filters, and at least one of Forum regulars has emailed Zeiss about this issue (and got a reply almost admitting that the lens falls short of ideal design). But is it?

An old Japanese folk-tale, discovered in a book of oriental myths and legends, and translated from the original Ancient Sumo script by David Kilpatrick.

THERE WAS once a beautiful Geisha called Minolta (here real name was Chiyoko but she adopted the stage name of Minolta once her fame spread abroad). She had many rivals, and was courted by many suitors.
