Sony announces New High-Speed α57 Camera Featuring Translucent Mirror Technology


A wider palette of creative options is now accessible to more shooters with the Sony α57 camera, the newest addition to Sony’s popular line of A-mount cameras employing Translucent Mirror Technology. The 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. This allows photographers to capture exactly what they see on the screen. Thanks to the BIONZ processor, creative shooting opportunities are boosted by an outstanding sensitivity range of ISO 100-16,000.

Ensuring detail-packed images, the 16.1 effective megapixel Exmor APS HD CMOS sensor is teamed with a latest-generation BIONZ engine. Refined by Sony during the development of its flagship α77 and high-end α65 cameras, this powerful processor effortlessly handles large amounts of image data for flawless, low-noise images and Full HD video. With the α57 camera, shooting speeds of up to 12 frames per second are achieved in new Tele-zoom Continuous Advance Priority AE mode, maintaining continuous auto focus and auto exposure with fixed aperture. Magnifying the central portion of the sensor’s image by 1.4x, it’s perfect for capturing split-second action close-ups with a burst of sharply focused images, even when the subject is moving. In this shooting mode, aperture is fixed at either f/3.5 or the maximum apertures of lens in use (whichever is smaller) and image size of photos is about 8.4 megapixels.

Even the novice photographers can now easily create pro-style portraits with the α57 thanks to new Auto Portrait Framing, a world’s first technology. Using face detection and the compositional ‘rule of thirds,’ the camera identifies a subject’s position, trimming the scene to create tightly framed, professional-looking pictures in portrait or landscape orientation while maintaining a copy of the original image. The new α57 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).
