Sony has expanded its Cyber-shot T-series of digital still cameras with the 5.1-megapixel DSC-T33 model. The camera maintains its slim design with a Carl Zeiss Vario-Tessar optical lens, which operates within the camera rather than extending outside. It also has a 3X optical zoom.

With a depth of just one-half inch, the new camera incorporates a 2.5-inch LCD viewfinder, which occupies about two-thirds of the back of the camera. The anti-reflection LCD enhances viewing quality by preventing reflected light from interfering with the displayed image. Other LCD improvements include higher contrast, brightness and resolution.

Sony's Real Imaging Processor circuitry makes it possible to shoot full-resolution images at one-second intervals. With optional Memory Stick PRO Duo media cards, the camera can capture and play back high-resolution motion video. The MPEG-VX fine mode helps to record MPEG video with 640-by-480-pixel resolution at 30 frames per second.

The supplied Cyber-shot Station USB cradle allows the DSC-T33 to play back slide shows on a television or transfer images to a PC. The camera also works with PictBridge-compatible printers. The DSC-T33 camera is available for about $450.
