With the minimally-designed Cyber-shot RX100, Sony puts a large sensor in a pocket camera—and with it, the promise of much higher-quality photographs. It comes with a 28-100mm-equivalent F1.8-4.9 image-stabilized 3x-zoom lens, and that 20MP Exmor CMOS sensor—about a third the size of APS-C—captures raw. On the back, a 3" LCD display and pop-up flash. The catch: it's $650. Imaging Resource has an exhaustive review.
