Sony Alpha 900 World’s First Full-frame 24.6 Megapixel DSLR

Sony Alpha 900 World's First Full-frame 24.6 Megapixel DSLRVast reservoirs of drool have started to form around the desks of photographers in Chez Digi-Lifestyles after the full details of Sony’s flagship new Alpha 900 digital SLR were released.

Sporting a full frame Exmor CMOS sensor offering an outrageously huge resolution of 24.6 megapixels, the A900 comes with dual BIONZ image processors, ISO sensitivity soaring up to the giddy heights of 6400, a 3.0-inch Xtra Fine LCD and nippy full resolution 5fps shooting.

The 24.MP full frame resolution is a world first, with Sony promising, “extraordinary image detail and wide dynamic range,” while the ground-glass optical pentaprism viewfinder offers 100% coverage.

A new Intelligent Preview function lets snappers fanny about with White Balance, D Range Optimiser and exposure level settings on the LCD screen without actually taking a picture, making it easy to pre-set exposure options before taking a photo.

Images can be saved on the Memory Stick Duo/Compact Flash Dual slot and the camera can be hooked up to a HD television, with a ‘PhotoTV HD’ mode providing optimised still image viewing.

In line with its pro aspirations, the camera comes with a full complement of dust and moisture by rubber seals, with a built in anti-dust system helping keep dust off the sensor when lens are being changed.

Sony has also created some new lens with Carl Zeiss glass to coincide with the A900’s launch, including a 70-400mm F4-5.6 G SSM telephoto and a Vario-Sonnar T 16-35mm F2.8 lens.
