Photoclub Alpha

Here is an article which is mainly a test review of the Sigma 50mm f/1.4 EX DG HSM for Sony Alpha, and also Nikon, fit (both were tested). It also deals with the Alpha 900 and D3X, the two 24 megapixel full frame cameras used to test the lenses and two comparison 50mm f1.4s.

After just a short while working with full frame, high resolution DSLRs the need for tilt lenses has really come home to me. Most lenses deliver their best results at fairly wide apertures like f8, it’s easy for detail to begin to look soft and lacking impact if you are forced to stop down to f22 to get everything sharp. Tilt adaptors and tilt lenses solve the problem. This article is repeated here after originally appearing on dPhotoexpert (and similar instrument images, in my first D3X test report for the British Journal).

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.

This set of full size shots was taken with the still life left set up, because the Nikon and Canon cameras were not here at the same time. It compares the A900, 5DMkII and D3X using the converters supplied by the makers – Image Data Converter SR2, Digital Photo Professional, and Capture NX2. Each small image in the article can be clicked to open a Level 10 quality full size JPEG – beware, the largest is over 13MB of data.

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.

If you are on the verge of making a decision, I’m here to help your think clearly – even if it means breaking some cherished behaviour patterns. I am going to help you think of the Alpha 900 not as a logical progression from the 700, but as a different camera system entirely.

The Alpha 900 – and indeed the Alpha 700 with new firmware v4 – offer a three-bracket sequence at a 2 stop interval to enable HDR blending, usually from static tripod-mounted views. At the Edinburgh Alpha 900 launch, I braced myself firmly against an open window, leaning out over the street, and tried an example hand held.

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!

There seems to be a lot of speculation about the Alpha 900 or Pro, and uncertainty about the timing of introduction. The August 14th date is not the 900, it’s two Cybershot models. The Alpha 900 will, as far as we are aware, be shown to the press on September 9th/10th worldwide.

Well, it looks as if the 14th August UK press conference for exciting digital camera news may not be about the Alpha 900 after all – Sony has just officially announced that some colourful little Cyber-shot models with ISO 3200 capability will be unveiled there, and no mention of the A900. Roll on September 9th!

Here’s Sony’s release on the new Cyber-shots – I apologise for leaving the hyperbolic advertising style adjectives (unusable editorially, and just a waste of words) in place:
