Sony A57 DSLT camera revealed

Sony has unveiled a new camera to sit in its line up of translucent mirror technology range of cameras, the a57 which offers 12fps shooting, full HD video capture and new creative options.

According to Sony, the Alpha 57 has been priced to appeal to a wide range of DSLR users, sharing many of the premium features found on the enthusiast level a65 – though the price has not been announced.

The a57 features a 16.1 million pixel Exmor APS HD CMOS sensor, which is teamed with the latest generation BIONZ image processing engine which has been designed for low noise stills and full HD video.

Shooting speeds of up to 12fps in new Tele-zoom Continuous Advance Priority AE mode are now available.

As on the a65, the a57 features a 15 point AF system with 3 cross sensors to help with TTL phase detection autofocus. Object Tracking AF has been enhanced to keep faces or other objects in sharp focus, even when the subject is momentarily obscured by another object.

Full HD video recording is included, with responsive full-time continuous phase detection AF to ensure moving objects stay sharply in focus. Full HD resolution movies can also be captured at a high 50p (progressive) frame rate, something which no other brand currently offers.

With the a57, Sony has introduced a new “Auto Portrait Framing”, which it claims to be a world first. This uses face detection and the compositional “rule of thirds” to identify a subject’s position and trim the scene to create a tightly-framed image.

By Pixel Super Resolution Technology is used to ensure that cropped and zoomed images retain the full pixel count. The original photo is saved together with the optimally-trimmed image, allowing for quick comparison between the two versions.

The same technology is used for 2x Clear Image Zoom, which doubles the effective magnification of the mounted lens.

An electronic Tru-Finder viewfinder is used on the a57, which Sony claims can rival quality optical finders. It offers 1440k dot resolution along with a 100% field of view and a number of high-resolution information displays.

A rear angle-adjustable 7.5cm (3 inch) Xtra Fine LCD screen is also included.

In camera picture effects include 11 effect types and 15 variations, which can all be added to images in-camera.

The Sony Alpha SLT A57 will be available from April 2012. UK pricing is yet to be confirmed.
