Exmor R hits the High Street – new Cyber-shots

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.

Nikon D5000 short film with pull focus

Though autofocus is not possible with live video in any current true DSLR (the Panasonic GH1 promises this) it is possible to use pull-focus effects with a little planning. We now have a Nikon D5000 – it won the competition for best fine image detail when comparing results frame by frame with Canon’s nominally higher resolution rival. It was also a very good deal, £629 inc VAT with an 18-55mm VR kit lens and a SanDisk Ultra II 8GB SDHC card plus Crumpler Messenger Boy 2500 bag thrown in free (from Jacobs). You Tube sample –

Nikon D90 – 4.5fps, HD video, 12 megapixels CMOS

Nikon has introduced some of the technologies we might expect to see from Sony, apparently using the IMX021 sensor (the pixel count on the long edge is 4288, rather than 4272 as normally processed from a Sony Alpha 700 file, but this is within the usual limits of different raw conversions). The D90 is an A700-class camera for £699 but includes Live View with face detection contrast-detect focusing, 720p HD movie recording up to 5 minutes, 4.5fps continuous shooting, ISO to 3200 (6400 HI), and Auto Distortion Correction when fitted with current Nikon lenses.
