The Sony T900 is based around a 1/2.3" SuperHAD CCD image sensor with 12.1 megapixel resolution coupled to a Carl Zeiss Vario-Tessar branded 4x optical zoom lens. The Sony T900 offers equivalent focal lengths that range from a 35mm wide angle to a 140mm telephoto, while the maximum aperture varies from f/3.5 to f/4.6 across the zoom range. Macro focusing is possible down to a minimum of one centimeter in what Sony dubs "magnifying glass" mode.. The T900 forgoes any optical viewfinder in favor of a 3.5" touch-panel wide-aspect LCD display with an extremely high 921,000 dot resolution.
The Sony Cybershot T900 offers ISO sensitivity ranging from 80 to 3,200 equivalent, and includes both true mechanical image stabilization, as well as Digital Image Stabilization which functions by raising the camera's sensitivity (and along with it, the noise levels) so as to achieve a higher shutter speed and reduce motion blurring. The Sony T900 also offers face detection capable of differentiating between children and adults, recognizing and prioritizing one specific individual's face whenever they're present in a scene, and detecting when your subject blinks during an exposure. The T900 takes into account the locations of detected faces when calculating autoexposure and autofocus variables. There's even a dedicated "Smile Shutter" button which triggers the T900 to capture a photo upon detecting that the subject is smiling. The Sony Cyber-shot T900 features in-camera retouching capabilities, with soft focus, fish eye effect, cross filter, partial color, retro, radiation, red-eye correction, trimming, unsharp masking and smile effects on offer.
Other features of the Sony DSC-T900 include eleven scene modes plus an Intelligent Scene Recognition mode which automatically chooses between a subset of these modes, plus 720p MPEG-4 high-definition video with stereo audio, a Dynamic Range Optimizer function, and both USB / high-definition HDMI video output connections. The T900's stylish body is available in a range of colors including silver, bronze, red and black. Pricing is expected to be in the region of $380, and availability is set for April 2009.
