The Contax logo and the leatherette panels on the SL300R T*’s body and the Carl Zeiss name applied to the lens may attract upscale buyers, but digital-camera aficionados will snap to attention over this 3-megapixel camera’s high-speed burst mode. It can capture full-resolution photos at three to four frames per second for as long as the action, your memory card, and your trigger finger hold out. If you want to shoot a few hundred photos in less than 60 seconds with a pocket camera that’s thinner than a deck of cards, this one’s for you.
