Review summary from DPReview
The A77 is a well-designed camera which spans the mid-range and semi-professional categories. Its headline features, high pixel count and blazingly fast continuous shooting, will attract a lot of interest, but of greater utility in day-to-day use are its effective ergonomics, reliable systems, and excellent full-time live view system and full-time AF.
Scoring is relative only to the other products in the same category.

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
Up to 530 Shots of battery life9
Take up to 530 shots on a single charge with Sony® Stamina™ battery power.9 Sony's InfoLITHIUM® battery system enables you to see the percent of power remaining, so you can keep shooting in confidence.
P/A/S/M exposure modes
The camera offers a full range of controls from the beginner's AUTO+ mode to P/A/S/M: Program, Aperture Priority, Shutter Priority and Manual. On-screen prompts help you refine your skills, build your confidence and exercise greater creative control.
|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.
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.
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 television.1 Records both JPEG and MPO file formats.
Advanced Anti-Dust Technology
Anti-Dust Technology helps keep the CMOS sensor clean, resulting in consistently clear pictures. First a static-free coating on the sensor's low-pass filter helps repel dust. Then vibration automatically dislodges dust from the sensor.
Built-in Flash (GN12)
To help you shoot more effectively, the camera includes a built-in flash (Guide Number 12) that can also trigger a wireless accessory flash (sold separately). The integrated hot shoe enables you to expand your lighting options with a range of accessory flashes (sold separately).
Slot for two media types
For cost-effective, convenient storage and sharing of your images, the camera accepts Memory Stick PRO Duo™/Memory Stick PRO-HG Duo™ and SD/SDHC/SDXC media (Class 4 or higher recommended, sold separately).
APS-C size HD CMOS image sensor
With 19.5 times the area of the typical camcorder image sensor, APS-C makes the difference between amateur and professional-looking video, delivering an exceptional combination of high resolution, high sensitivity and gorgeous, blurred backgrounds.
|Sweep Panorama™ Mode |
Capture expansive landscapes automatically. Press the shutter, sweep vertically or horizontally. The camera does the rest, continuously shooting images and stitching them together.
An integrated GPS receiver records the location and time of every shot you take and lets you view your images on a map with compatible computer and Internet applications, so you can remember where you took your favorite shots.6
Shot Result Preview
See the results before you take the shot. This preview takes the guesswork out of camera settings by showing the effects of the aperture, shutter and DRO settings on the depth of field, motion and dynamic range.
921K dot TruBlack™ LCD screen
Sony's 3.0-inch Xtra Fine LCD™ monitor has 921K dots for superb resolution. The TruBlack™ screen includes a special resin layer to suppress internal reflections, increasing contrast compared to conventional LCDs. Sunny Weather mode boosts visibility even further.
Main Sensor Quick AF Live View
Combines the fast focus of Phase Detection AF with high quality Live View images right from the main sensor. This is made possible by Sony® Translucent Mirror Technology. You get accurate images and 100% framing on the LCD monitor or eye-level viewfinder.
ISO 16000 sensitivity
Incredibly clear low-light pictures without sacrificing detail, made possible by the low-noise Exmor® APS HD CMOS image sensor and refined BIONZ image processor.
AUTO+ (Advanced Auto) mode
Get cleaner, more dynamic pictures and fewer missed shots. Unifies and simplifies Sony intelligent technologies. The camera automatically recognizes the correct scene mode.
Clarifies the relationship between aperture and shutter speed, as well as the effect each has on photographic results.
Upgraded BIONZ® image processor
The brain of the camera is a Sony's BIONZ® image processor substantially upgraded for the demands of 24.3 megapixel photography. Chroma noise reduction delivers high-resolution, low-noise photos even at ISO 16000. Also enables fast processing for up to 12 fps continuous shooting of data-intensive 24.3 MP images, 2D/3D Sweep Panorama™ modes and 6-image layering.

1200-Zone exposure metering
Reads exposure directly from the main image sensor. Choice of Multi, Center and Spot metering accommodates a full range of shooting situations.
Sony Exmor® technology
Conventional image sensors use only a handful of analog-to-digital (A/D) converters, which can slow you down. The Exmor® sensor provides more than 5,600 column-parallel A/D converters. This helps enable continuous shooting at up to 12 frames per second.
11 Picture Effect modes
Discover innovative ways to make your images and videos pop. These include Posterization (Color, B/W), Pop Color, Retro Photo, Partial Color (Red, Green, Blue, Yellow), Soft High-key, High Contrast Monochrome, Toy Camera, Soft Focus, HDR Painting, Rich-tone Monochrome, and Miniature.
Face Detection and Registration
The camera can automatically detect up to eight individual faces and adjust focus, exposure, white balance and flash to help deliver crisp, properly lit images of people. Can prioritize children or adults. Face Registration can remember friends and family members and prioritize them.
Smile Shutter™ technology
Captures a smile the moment it happens. Simply select the Smile Shutter™ mode and the camera takes the picture automatically. You can prioritize children or adults and adjust the smile sensitivity.

Top Customer Reviews
Most of the professional reviews I've found for the Sony a77 (dpreview, etc) are entirely missing the point. The electronic viewfinder alone is reason enough to consider this camera a step up from a traditional DSLR, even if the DSLR you were comparing an a77 with had identical specs. I'd say the a77's viewfinder is a pleasure to use (and it is), but even that is missing the point.
This viewfinder will change the way you use your camera. It'll change it for the better because it gives you greater control over the camera than you've ever had before.
Because the viewfinder is an OLED video screen in the eyepiece instead of being a typical piece of glass, you're seeing something entirely different. Something more useful.
An optical viewfinder shows you what the lens is seeing. An electronic viewfinder shows you what the sensor is doing. Think about that for a moment. Let's say you own a Nikon D7000 and you boost exposure compensation. Do you see any change in the viewfinder? Of course not. You'll see that change in the photo you take. That's how SLRs have always worked, even back in the days before digital. Ah, but with the electronic viewfinder in a Sony a77, when you boost exposure compensation, you'll see the image in the viewfinder become brighter, just as the shot you take will be brighter.
An even simpler example: Look through the viewfinder of a DSLR and choose an exposure point. Pick a dark spot. Nothing changes in your viewfinder, right? Pick a bright spot. Do you see any change in the viewfinder? Of course not.Read more ›
Look and Feel
If you have never handled a pro or semi-pro camera body, the tactile difference between a polycarbonate and magnesium alloy shell is immediately noticeable. Even though the body only weighs a little over 1½ lbs (without lens), it feels solid. It has a rubber grip that extends around the back on the right to cover the thumb rest area. The grip itself is deep and fits my medium-wide hands comfortably with a secure feel when holding it one-handed. The body is a little taller than the A700 but more rounded with a matte finish that gives it a no-nonsense appearance.Read more ›
Haven't updated in a while so here we go!
We are now on bodies number 15 and 16 of these fabulous cameras. We shoot a lot of photos so we change out bodies every 3-4 months so we don't run the shutter count too high and ruin the resale. We shoot 250,000-300,000 photos a year currently. Sony has fixed the bug that made me have to keep rebooting my first camera, as a matter of fact we've had zero camera problems since the first 3-4 bodies. We believe that this is the perfect camera for what we do and will continue to use them until they are no longer available. After trying several point and shoot zoom cameras we also settled in on a Sony HX-50. It is an excellent 24-1200MM 20MP camera with excellent video. I use ours for all of our video needs exclusively :D
Last week we put our 2 SONY SLT-A77s through the ultimate test.
We were the official photographers on the Rock Legends Cruise and shot over 9,000 excellent photos over 3 days. I had to only reboot my A77 3 times but my wife did not have to reboot hers at all.
We shot about 65% of the concert photos with no flash in low natural stage light and got amazing results with very little ISO noise problems.
We also shot our 1st and 2nd rock videos with the A77 and were amazed at the results. I was set up about 15 feet from the main PA system right stack and the sound was not blown out even though I only used the on-board microphone. The stereo sound is crystal clear and other than some faint wind that was picked up the audio was perfect!Read more ›
