Sony Announces Alpha-57 Single Lens Translucent Mirror Camera


The new Sony SLT-a57 translucent mirror camera updates the original alpha’s fixed-mirror, electronic viewfinder DSLR with the latest Bionz processor, 12 fps with continuous autofocus, and full HD video at 60p, 60i or 24p frame rates.

Sony said their innovative Translucent Mirror design directs incoming light to the CMOS image sensor and the AF sensor at the same time, allowing full-time continuous AF during both still and video shooting. Users can also frame, focus and preview shots in real-time on the high-resolution Tru-Finder electronic viewfinder, which offers a wide viewing angle and 100% field of view, allowing photographers to capture exactly what they see on the screen.

The a57 model shares the a65’s 15-point AF system with three cross sensors delivering fast, accurate TTL phase detection autofocus. Newly enhanced Object Tracking AF keeps faces or other selected objects in sharp focus –¬†even if a target is obscured momentarily by another passing object.

The new a57 interchangeable lens camera will be available this April with an 18-55mm kit zoom lens for $800 (model SLT-A57K). It will also be offered as body-only for about $700 (model SLT-A57).
