Excerpt: The Sony SLT A57 DSLR is a tidy still snapper with its 16.1 megapixel sensor, but it also pulls double duty as an HD camcorder: it can suck down full HD 1080p resolution video. But is it a jack of all trades and master of none? Check out our group test in the video above to find out.
Summary: Experts note, however, that you can use Clear Image Zoom, Auto Portrait Framing and some other features only if you're shooting JPEGs. They're not available in raw mode. For video, Sony includes an on-board stereo microphone and an external mic jack. It also offers exposure bracketing, a helpful photo feature found on entry-level Canons but not the Nikon D3200.
Pros: Speedy burst shooting, Image quality rivals DSLRs, Nifty features you won't find elsewhere, Great LCD and electronic viewfinder
Cons: No optical viewfinder, Menu could be easier to use, Low-light images get mixed reviews, Loud zoom shows up on video
We took Sony's sub-$1000, 10fps speed demon, the A57 DSLR, for a spin around New York City.

Excerpt: The Sony Alpha A57 is the latest SLT interchangeable lens camera from Sony. Replacing the A55, the Alpha A57 features the same pellicle mirror technology, allowing for fast shot-to-shot speeds and phase-detection autofocus even while recording video. Sony claims this results in 10fps continuous shooting while continuously focusing on a moving subject. The camera also features 1080/60p, a 3-inch swivel screen, 15-point AF, and a 16.1-megapixel EXMOR CMOS image sensor.
Summary: Aside from its more enthusiast-focused design, the A57 can't be said to be a significant update over the A55 it replaces. True, this isn't entirely a bad thing, as it shares many of that camera's positive attributes, from its snappy focusing performance and reliable image and video quality, to the handful of features which make it as enjoyable to use as the camera is capable.
Summary: The A57 combines a high quality 16MP sensor, easy access to shooting parameters and class-leading video performance. And does this while providing an equivalent shooting experience whether composing images via the EVF or rear LCD.
Pros: Very good Raw file output up through ISO 6400, Dynamic range at the top of its class, High magnification EVF with comprehensive information display, Manual focus 'Peaking' option for both stills and video modes, 10fps shooting in full resolution mode, Class-leading 1080/60p video resolution with manual exposure control, Useful function menu provides access to shooting parameters, Two customizeable buttons (AEL and ISO) with wide range of options, Fully articulated rea...
Cons: Mediocre JPEG processing with mushy detail and visible artifacts, LCD viewfinder (vs OLED panel in other Sony models), AF not compatible with manual exposure control in video mode, No live view in 8 or 10 fps continuous shooting modes makes accurate panning very difficult, Counter-intuitive setting of aperture in manual mode, Awkward to navigate between stills and movie playback modes, Main menu system is tedious to navigate, Clear Image Zoom offers no IQ benefits ove...
