Sony a77 Camera and 18-135mm Lens
Redefining the camera. Get action photos, HD Movies and Live View shots that other cameras miss, thanks to Sony’s exclusive Translucent Mirror Technology. Enjoy 24.3 megapixel resolution—with the world’s fastest shooting— up to 12 frames per second—and the world’s first OLED electronic viewfinder.2

2nd Generation 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 August 2011.

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 August, 2011.

World’s first OLED viewfinder2

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 Movies4. 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 control4

Now you don’t need to surrender control when you shoot HD movies.4 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

Rugged, magnesium alloy body

The SLT-A77 is built for the real world with a magnesium alloy body that combines high strength with light weight. Ports, doors and controls are also weather-resistant for smooth operation under adverse conditions.

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.

6-image layering

Leverages the fast BIONZ® processor to capture six images in a fraction of a second, and then combine the data. The result is one incredible single image that gets a cleaner result in Multi-Frame NR mode or sharper nighttime pictures in Hand-held Twilight mode.

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 16000. (Recommended for still subjects.)

Handheld Twilight mode

Get gorgeous shots at night without a tripod. Combines six frames into a single image for smooth, low-noise evening shots. (Recommended for still subjects.)

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. (Recommended for still subjects.)

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 television1. Records both JPEG and MPO file formats.
