Summary: Handheld Twilight Mode pulls the same trick so you can shoot at night without a tripod. The A77 also packs plenty of "good old-fashioned manual control," DPReview.com says, including controlling external flashes wirelessly, fine-tuning the autofocus, and offering full manual control over video. There is, however, only one memory card slot.
Pros: Ultra-high-resolution, 24-megapixel sensor, Extremely fast burst shooting, Image quality rivals DSLRs, Great LCD, electronic viewfinder
Conclusion: Although on the expensive side, the Sony SLT-A77 is one of the best DSLRs we’ve reviewed in the past year or so. The combination of high-quality stills and excellent video – without focusing hassles – takes this camera to Editor’s Choice status. The camera’s not perfect, but you can tweak the results to your tastes as you master its many options. We recommend this camera with the DT 16-50mm lens to anyone willing to make a serious imaging investment.
Pros: Excellent still and video quality, Terrific OLED viewfinder, 12 fps shooting
Summary: The A77 is definitely a good buy if you're looking for something sturdy, with a good overall balance of features and performance. While the A77 is a slight disappointment in the noise handling department, it definitely makes up for it with the fast AF (especially if coupled up with one of Sony lenses that feature Super Sonic Wave Motors) and stellar video quality.
Pros: Weather sealing and Magnesium Alloy body, burst mode of 10 frames per second (with AF tracking), Cheapest of the competitors
Cons: ISO performance not up to par, Flash casts a shadow with kit lens
The Sony Alpha A77 offers just about everything you'd want in a modern system camera.

Conclusion: The A77's familiar design is packed with fresh, useful, well-executed technology that enhances the shooting experience without really changing the traditional feel that photographers love. This camera is a love letter to loyal A-mount shooters, and a tempting new direction for competitors to consider. The chief reason to buy the A77 over any other DSLR is pure speed. The fixed, translucent mirror is a brilliant design.
Conclusion: The Sony Alpha A77 is a major leap forward for the company in DSLR design, features and image capabilities, finally putting Sony into the competitive mix with Canon and Nikon in the prosumer DSLR marketplace. The A77's 24.3-megapixel APS-C sensor, Translucent Mirror Technology and 12 frames-per-second capture rate changed everything for Sony.
Pros: 24.3-megapixel APS-C sensor offers great resolution for a prosumer DSLR, Unique Sony translucent-mirror tech provides full-time phase-detect autofocus, Full-time live view by default, 12 frames-per-second capture rate, Fast autofocus, burst, shutter lag, shot-to-shot and continuous mode speeds, Full 1080p HD video recording, at up to 60 frames per second, 60fps video mode is true 60fps from the sensor, not frame-doubled 30fps, Live phase-detect autofocus during video ...
Cons: Somewhat heavy for a prosumer DSLR, Uses an EVF instead of an optical viewfinder; EVF appears dim when used in bright light, Camera doesn't switch fast enough between the LCD viewfinder and EVF after viewfinder detects you're looking through it, leaving you in the dark for a brief moment, Images sometimes a little underexposed, Noise suppression gets in the way of truly sharp pictures at ISO 1,600 and above, Continuous AF in Movie mode only works with large apertures ...
Camera Test: Sony's A77 Is The New King of APS-C DSLRs
9 February 2012
Excerpt: When we named Sony's Alpha 55 Camera of the Year last year , we didn't expect that the company would come along with a model like the new Alpha 77. In addition to the benefits we loved in the A55, such as full-time phase-detection autofocus even when recording video, Sony has added a slew of features for this flagship fixed-mirror DSLR. With all of this new technology, we were eager to get it into the Popular Photography Test Lab.
Conclusion: The Sony Alpha 77 pumps out 24-megapixel stills at 10.3 frames per second and records 1080p60 video with continuous autofocus. Solid low-light performance, a sharp f/2.8 kit lens, a high-quality OLED EVF, and GPS capability round out the package.
Pros: Excellent kit lens. High-resolution sensor. Fast burst shooting. Good high ISO performance. 1080p60 video with autofocus. Crisp OLED EVF. GPS.
Cons: Recovery time needed after burst shooting. No optical viewfinder. Proprietary hot shoe.
Pros: big, big 6000×4000 pixel stills; 12fps ability; terrific movie mode; top drawer exposure modes; you want to explore high end photography without the tech tangles of a high end camera (like the Canon 7D).
Conclusion: That said, when weighing these up against a superb level of image quality when shooting in most conditions, great handling, good build quality, industry-leading EVF, quick full-time phase detection AF system and a comprehensive set of exposure modes, we have little trouble with recommending this excellent camera.
Summary: 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.
Pros: Excellent 2.4 million-dot OLED EVF, Versatile full-time live view system, Very high-resolution 24MP CMOS sensor (but see caveats in 'cons', below), Exceptionally 'deep' feature set including Auto HDR and Sweep Panorama, Class-leading video resolution, Solid, well thought-out ergonomics, Fast and responsive operation, Very good continuous shooting performance (particularly with UHS-I memory card), Efficient SteadyShot INSIDE image stabilization system, In-camera GPS, G...
Cons: In-camera JPEGs don't show off the 24MP sensor to its best extent, Comparatively strong noise reduction at medium and high ISO settings, Very noisy raw files at high ISO settings, Little control over high ISO noise reduction in JPEG mode ('auto' or 'weak'), Limited control in 12 fps continuous shooting and movie modes, No live view in 8 or 12 fps continuous shooting modes makes accurate panning very difficult, Menu system a little confusing (hard to orientate yourself...
