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.

Nikon is holding a launch today (June 30th) in London, and presumably worldwide. Richard Kilpatrick is attending for Icon Publications Ltd. As at 1.30am Monday, no press release has been received from Nikon, so we can assume an embargo will be in place but news may be released around 10.30am Monday 30th (GMT).

The launch is expected to reveal a low-cost 12 megapixel ‘full frame D300′ based on the sensor used in the D3, with a D100-type body like the D300. It may also preview the D3X, a full frame 24.x megapixel D3-type body using the new Sony high resolution full frame sensor.

We had early information that Sony would launch new products in June, which now has one day to go. The 58 flashgun may have been the only launch for June. A possible clue to imminent roll-outs may be that new Sony point of sale cabinets have space for products which the dealers don’t yet have! The 24-105mm f/4 G SSM has already been leaked but we can expect two more key lenses in the wide angle and medium tele zoom ranges. Rumours of a June 30th launch may apply to the Nikon conferences, not Sony.

My bet is that the first we may actually see of some new items for sale will be in the window of Foto Gregor, Cologne, around September 23rd. We shall be at photokina from the press day on September 22nd – watch this space!

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.

There’s a lot of controversy right now about whether or not the image structure of the Alpha 700 files at very high ISO – mainly 3200 and 6400 – is as clean as raw processed results from other comparable cameras like the Canon 40D (does not offer ISO 6400), the Olympus E-3 (does not offer ISO 6400) or the Nikon D300. At the heart of this is the way different raw processors handle file conversion, and most specifically, the current performance of Adobe Camera Raw 4.3.1.

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.

The latest full release – no longer Beta, and accepting previous C1 Pro activation keys for unlimited access but otherwise now on 30-day trial – of Capture One v4 now handles Sony Alpha 700 raw files and transforms high ISO rendering in comparison to the industry standard Adobe Camera Raw.

NOT everyone will want the live view offered by the A300 and A350 – it does turn out to be more or less as we suggested, a secondary optical path adjacent to the eyepiece inside the prism housing. I’ll explain here exactly what the implications are, and why a future model – let’s call it the A500 – offering the 14.2 megapixel sensor without the live view may be worth waiting for.

Sony Corporation today announced the development of a 35mm full size (diagonal:43.3mm) 24.81 effective megapixel, ultra-high speed high image quality CMOS image sensor designed to meet the increasing requirement for rapid image capture and advanced picture quality within digital SLR cameras.

In mid 2007, rumours of a 14.8 megapixel Sony sensor came from the usual Far Eastern ‘inside’ sources. As a full-frame Alpha model (the so-called 900) had been previewed at PMA 2007, it was possible this megapixel count related to full frame, or near-full frame. It now looks as if it may have been a leak of development for currently rumoured 14.2 megapixel (active) Alpha 350, which is an APS-C sensor camera.
