Translucent Mirror Design
Other DSLRs can shoot. Or they can focus with the speed and precision of Phase Detection AF. They cannot do both at once. Sony changes all that with the award-winning Translucent Mirror Technology system. It directs light to both the image sensor and the Phase Detection AF sensor simultaneously.
24.3 MP; best-in-class resolution2
You get incredible detail and gorgeous enlargements thanks to a 24.3 megapixel sensor. It's the highest resolution among APS-C DSLRs, as of November 2012.
World's fastest up to
12 fps continuous2
The translucent mirror makes it far easier to capture the decisive soccer kick or your baby at her absolute cutest. Shoots up to 12 frames per second at full-resolution 24.3 megapixels with continuous auto focus (AE locked after first frame). This is the world's fastest shooting speed for interchangeable lens APS-C cameras, as of November, 2012.
World's first OLED viewfinder
There's never been anything quite like the Tru-Finder™ OLED electronic viewfinder. For size, speed and brightness even after sunset, this is a gem. It begins with 2359K dots for amazing resolution and high contrast ratio for incredible depth. OLED reduces motion blur to a bare minimum. You can also see the results of camera adjustments in real time with superb color and detail.
HD Movies4 at 60p, 60i, or 24p
Capture spectacular HD Movies. This is the world's first DSLR to offer a choice of super-smooth 60p, standard 60i or cinematic 24p, all at Full HD 1920x1080 resolution. AVCHD™ codec delivers stunning picture quality. MP4 codec offers smaller files for easier upload to the web.
HD movies with full manual control
Now you don't need to surrender control when you shoot HD movies. Enjoy the full expressive potential of Program, Shutter Priority, Aperture Priority or Manual (P/A/S/M) control in
HD movie mode.
Full-time Phase Detection AF
You get fast, accurate auto focus in every mode—even HD Movie and Live View—thanks to Sony's exclusive Translucent Mirror Technology. While Contrast Detection Auto Focus often hunts for correct focus, Phase Detection AF knows exactly where correct focus is, and goes straight for it.
Full-Time Live View in LCD or EVF
You can use both the LCD monitor and OLED Electronic Viewfinder for composing shots in Live View. Both provide a what-you-see-is-what-you-get preview of white balance, focus, depth of field, exposure and 100% framing accuracy, plus informative on-screen displays.
World's shortest release time lag3
Helps ensure that the image you want is the image you get. Once auto focus occurs, release time lag is the delay between fully pressing the shutter release and when the camera actually starts taking the picture. Long lag makes it harder to capture fast-moving objects. The Sony A77 boasts the world's shortest release time lag at only 0.05 seconds.3
SteadyShot INSIDE™ stabilization
Image stabilization reduces blur by compensating for camera shake. Typical DSLR systems build image stabilization into selected lenses only. SteadyShot INSIDE™ image stabilization is built into the camera body itself. You'll reduce blur with every A Mount lens, including macro and wide-aperture standard zoom lenses.
HDMI® output for HD viewing
Enjoy HD movies and stunning still images on a compatible HDTV.7 The camera includes an HDMI® output. In addition, the BRAVIA® Sync system works with compatible Sony® BRAVIA HDTVs enabling you to control camera playback using the television's remote.8

Object Tracking AF
Locks onto a specified object and maintains focus even as the subject moves. Unpredictable subjects stay in focus even while zooming. You can concentrate on composition without worrying about focus.
19-point Auto Focus
To maximize the value of Translucent Mirror Technology, Sony incorporates Phase Detection AF of great sophistication. 19 sensors with 11 cross sensors maximize precision for both vertical and horizontal subjects.
Three-way tilt/swivel LCD screen
Tilt it up or down to frame high- and low-angle shots that would otherwise be hit-or-miss. Tilt and swivel over the camera for self-portraits. You can even tilt it up and down when you hold the camera in vertical mode! Finally, the monitor folds flush to the camera with the LCD exposed for shooting or protected for travel.
Dual control dials
Perfect for experienced shooters, dual control dials provide direct, hands-on access to two settings at a time.
Top mounted LCD
In addition to status displays on the LCD monitor and Electronic Viewfinder, Sony offers a top-mounted LCD with exposure information.
