Sony didn’t so much enter the market for small and thin digital still cameras as break down the door when it unveiled one that’s about the size of a pack of playing cards. Sony claims the camera is the smallest 5-megapixel model currently available. The DSC-T1 is tall and thin and sports a 2.5-inch LCD monitor on its rear and at 5 megapixels it also outshines the competition in terms of image resolution. There’s a Carl Zeiss 3X optical zoom lens and maximum resolution is 2592 x 1944 pixels. It can also record MPEG1 format video and audio at 640 x 480 pixels (VGA) resolution at 30 frames per second. The camera measures 91 x 60 x 21 millimetres and weighs 180g with a memory card and battery inserted. The DSC-T1 will be available in Japan this month and costs around $US555. Sony plans to sell the camera overseas.
