Capture your perfect moments with Sony's next generation Translucent
Mirror Technology DSLR enabling simultaneous focus and capture.
Shoot up to an amazing 12 fps in Tele-zoom High speed mode,
complete with continuous auto focus. Auto focus is also visibly faster in
Live View and HD Movie modes.
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 @ 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 AVCHD™ format or in PC-friendly 1080/30p MP4 format.
Eye-Level Electronic Viewfinder
The Tru-finder™ Electronic 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" 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 INSIDE™ stabilization
Image stabilization reduces blur by compensating for camera shake. SteadyShot INSIDE™ image 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.
