Nikon has announced a new mini compact camera, the Nikon Coolpix S01, for those who want to take great shots, but not have something bulky in their bag.Measuring 51.2 x 77 x 17.2mm and weighing 96 grams, the camera - smaller and lighter in virtually every dimension than the iPhone 4S - will sport a 10-megapixel CCD image sensor and a 3x optical zoom (29 to 87mm) alongside a 2.5-inch touchscreen display.According to Nikon, the new graphic user interface (GUI) offers an easy-to-tap four-segment home screen that streamlines operation."By tapping a subject, the shutter is automatically released when focus and exposure are fixed, while various image effects set prior to shooting can be applied to pictures," Nikon says.
