SONY puts two 10.2 megapixel consumer digicams on the market in September 2009 using the back-illuminated Exmor R sensor. This CMOS sensor architecture takes the ’sandwich’ which forms the light-sensitive pixel wells, and reverses it so that the side previously used for connections now faces the image-forming light. This change allows more light to be captured, resulting in improved high ISO performance. So far, the Exmor R technology has only been used in video cameras and this is the first appearance of it in still cameras. The cameras can shoot at 10 frames per second.

Gustav Kiburg has done an extensive test between these two lenses, posted in a Dyxum.com forum thread:

It’s well worth checking out.

Like Mike Johnston writing in The On-Line Photographer, I’m aware that any attempt to line up one or more cameras and show comparison images or make judgements is on to a loser from the start. And any webmaster who puts an external link in the first half dozen words of a new post is losing the plot too! But here, for what it’s worth, is the first line-up of results processed using the same software from A900 and D3X uncompressed raw files converted without sharpening or noise reduction.

Following the review on dPreview – more than anywhere else – Sony’s extremely poor JPEG engine with its associated wide radius chroma blur and strong luminance smoothing noise reduction has proved to be a dog well capable of biting its master. Definitely a dog, anyway. But this performance is not what the camera can really achieve. In fact it’s perfectly capable of delivering good high ISO shots in typical situations.

Here, for some light relief, is an Alpha 700 + 24-105mm Minolta D documentary on the press dinner thrown for journalists from all the countries of the European region when they gathered in Edinburgh for the Alpha 900 launch!

TODAY Sony’s Alpha 900 was unveiled to European journalists at a press conference held in the Caledonian Hilton Hotel, in the very heart of historic Edinburgh shadowed by the Castle and looking out over the west end of Princes Street gardens. The price for the body only will be £2,100 inc VAT from Sony Style Europe and the camera will be delivered in October – SonyStyle begin taking orders on September 10th.

Sony chose the anniversary of the Battle of Flodden Field (September 9th, 1513) for the launch conference and the anniversary of the last battle fought between England and Scotland as two nations (Pinkie Cleugh, near Edinburgh, September 10th 1547) for their field trip… the English press were made most welcome!

Duncan McEwan, Scottish regional organiser for the Photoworld Club and a regular contributor to the magazine, played a key role in the launch as one of the European beta testers who has been using the camera over the summer period.

Duncan has used the A900 with the 24-70mm and 70-200mm SSM only, and tells me that his main interest was to see whether it did what he wanted – not to compare it with the A100, A700 or any other camera!

It’s not going to be long before we see the Alpha 900, and some cameras are known to be out there on trial in the hands of Sony staff and pre-release testers. I am not one, so rest assured, this is not a leak! What can you expect from the Alpha 900’s full-frame prism finder?

(Note: this post was written in early August – it is now 100% certain that the finder is 100%, and at 0.74X magnification will be – as had been hinted – the largest of all current DSLR finders in apparent visual terms except the EOS 1Ds Mk III which is 0.76X. Comparisons: EOS 5D 0.68X, Nikon D3 0.70X).

The Photoclub Forum has really picked up in the last few weeks. We now have (as I write):

Total posts 2869 • Total topics 607 • Total members 894

That’s a long way from the early days – this site only went live just over a year ago though we have ‘date stamped’ some pages to make them match the Alpha launch back in June 2006. It’s a very friendly place, with a wealth of technical information and help and some very detailed responses from some expert users.

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.

WE trialled a ZMags version of the January 08 issue of Photoworld here. We then looked at Uniflip. However, all these places want a few hundred dollars to leave a slightly adjusted Flash or Java version of a PDF we create, on their server for 12 months. The ZMags trial is now removed and after testing Uniflip, it was clear we had no reason at all to use this service either.

You can simply download a modest sized PDF (72 dpi screen res) of the January08 Issue here instead…

The first SONY World Photography Awards were presented in the late April sunshine of Cannes, to what must have been an exclusive gala dinner audience – at €250 a head, our ‘man on the spot’ Thomas Goseberg decided against the opportunity to take his wife out for a quiet meal…

New photo website Myelephantbites.com offers the chance to turn digital photographs into animated movies by combining digital images with sound, words and special effects. The site would like to reward Photoworld readers with complimentary trials forthe first 1,000 readers. We have now extended that offer to Photoclubalpha website visitors, as we said we would do so early in February.

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.

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.
