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
Summary: The Sony Alpha SLT-A77 has been a long time coming — the company’s latest DSLR was announced in August, but production delays have kept it from being widely available even now. Many people have waited eagerly for it, though, and with good reason: the 24.3-megapixel APS-C sensor (the same one that does so well in the A77’s smaller cousin, the NEX-7 ) promises huge, beautiful images, and Sony claims the camera can shoot 12 frames per second.
Pros: Excellent image and video quality, Ridiculously fast, Fantastic kit lens, Built-in GPS, Superior Live View and autofocus performance
Cons: Inferior low-light performance, Lens ecosystem lags Canon and Nikon, EVF isn't as good as an OVF, Mediocre battery life
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.

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.
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).
