Translucent Mirror Technology

Other DSLRs can shoot. Or they can focus with the speed and precision of Phase Detection AF. They cannot do both at once. The SLT-A57, with Translucent Mirror Technology?, directs light to both the image sensor and the Phase Detection AF sensor simultaneously.

Up to 12 fps Tele-Zoom High Speed Shooting

By capturing the center 2/3 of the image sensor (8.4MP), Tele-zoom high speed shooting brings the action closer with a 1.4x effective increase of focal length. Shoot up to an incredible 12 frames per second with continuous auto focus and auto exposure to capture the decisive moment.

Up to 10 fps at 16.1MP capture

Shoot up to 10 frames per second in incredible detail with the 16.1 megapixel Sony Exmor APS HD CMOS sensor, the camera achieves high resolution with no penalty in low-light sensitivity or sensor noise.

Clear Image Zoom

Utilizing Sony?s exclusive By Pixel Super Resolution Technology, Clear Image Zoom increases the effective focal length of your lens up to 2x by digitally magnifying the center of your image with nearly imperceptible degradation. It virtually doubles the effective focal length of whatever lens you?re using providing greater shooting flexibility.

Auto Portrait Framing

Simply photograph a person and Auto Portrait Framing will save an additional, optimally framed image in portrait or landscape orientation. Combining Face Detection and By Pixel Super Resolution technologies with rule of thirds, Auto Portrait Framing provides beautifully composed and appealingly balanced full resolution portraits.

Full HD 1080/60p/24p movies

This is one of the very few DSLRs with super smooth 1080/60p/24p Full HD recording capability. Records in your choice of 1080/60p AVCHDformat or in PC-friendly 1080/30p MP4 format.

Eye-Level Electronic Viewfinder

The Tru-finderElectronic Viewfinder (EVF) is super bright, easy to see with 1.04x magnification, ultra-sharp with 1.44 million dots (effective) and provides 100% frame coverage. Exposure preview and informative overlays make operation easy.

Tilt/swivel 3 inch LCD screen

Tilt it up or down to frame high- and low-angle shots that would otherwise be hit-or-miss. Tilt and swivel under the camera for self-portraits. Fold it flush to the camera with the LCD exposed for shooting or protected for travel.

Auto HDR built into camera

Captures more scene dynamic range than a single exposure can handle?and more range than photo film. Combines the best highlight detail from one shot, the best mid-tones from a second and the best shadow detail from a third for one incredible shot. Captures in a split second. (Recommended for still subjects.)

SteadyShot INSIDEstabilization

Image stabilization reduces blur by compensating for camera shake. SteadyShot INSIDEimage stabilization is built into the camera body itself. You'll reduce blur with every A-mount lens because it provides compensation equivalent to approximately 2.5 ? 4.5 steps in shutter speed, allowing for more hand held opportunities in low light or longer focal lengths.

15-point Auto Focus

To maximize the value of Translucent Mirror Technology, Sony incorporates Phase Detection AF of great sophistication. Three cross sensors maximize precision.

Object Tracking AF

Using the 15-point autofocus sensor and Sony?s subject recognition technologies, Object Tracking AF can maintain accurate focus on your subject even when it changes position in the frame.

Multi-frame NR

Experience incredible low-light shooting without a flash. The camera captures six images in a fraction of a second. Combining the data from all six, it creates a single image with a reduction in noise equivalent to two additional steps of ISO sensitivity. Sensitivity selectable up to ISO 25600. (Recommended for still subjects.)

Hand-held Twilight

Get cleaner and sharper nighttime pictures?beyond the capability of traditional cameras?without using flash or a tripod. The camera captures six images in a fraction of a second. Combining the data with separate algorithms for still and moving parts of the picture reduces blur, minimizes noise and enables extraordinary detail.

Sweep PanoramaMode

Capture expansive landscapes automatically. Press the shutter and sweep vertically or horizontally. The camera does the rest, continuously shooting images and stitching them together. Up to 23 MP image size.

3D Sweep Panorama Mode

Capture vast scenic vistas and 16:9 shots in spectacular 3D. As you sweep across the panorama, the camera records separate right-eye and left-eye images that make landscapes come alive on your 3D television.3 Records both JPEG and MPO file formats.

Picture Effects

Ordinary scenes become extraordinary photos and movies with Picture Effects. Choose from 11 modes and 15 effects that significantly increase visual impact by adjusting camera parameters and applying advanced processing techniques.
