Sony is pioneering new digital imaging technologies that redefine what a camera can do. Their Translucent Mirror Technology, employed in Sony Alpha DSLRs, provides the speed and precision of phase-detection AF but with a fixed, semi-transparent mirror, for ultra-fast frame rates, uninterrupted auto focus, and no viewfinder blackout during exposure. Sony is also leading the mirrorless revolution with their NEX series of cameras, which feature large APS-C sensors and pro performance in a very compact, lightweight body. Both the Alpha and NEX systems offer a broad range of top-quality optics and unique accessories to help you achieve stunning still images and captivating HD video.
