Sony a57 reviews:

The Sony A57 is a considerably larger camera and more closely resembles a traditional DSLR than its predecessor A55. In terms of body design the a57 is virtually identical to the a55. More about body and design of Sony a57 as well as many tests of image quality you can find on Sony a57 review from website.

A great Sony a57 review comes from website. The autor of this review notes that Sony Alpha A57 features a 15-point phase detection autofocus system with 3 cross-type AF points. Because A57 has a translucent pellicle mirror technology, the camera can utilize phase-detection autofocus even while shooting in live view, recording video or using the electronic viewfinder. The autor of a57 review also says:

The main additions to the A57 are support for AVCHD 1080/60p video recording, 12fps continuous shooting (10fps at full resolution, but with continuous autofocus), Sony’s Superior Auto+ shooting mode, and a new auto portrait framing mode. The additions are welcome, and add to a host of on-camera modes and tools designed to aid beginner shooters.


The Sony A57 records full HD video at 50p using the AVCHD 2.0 codec. When a good optic is used the level of detail in video recording is excellent, with AF system immediately bringing subjects into focus. More about this you can read on website.

Another short Sony a57 review comes from website. There you can read about some features of Sony a57 and you can see examples of photos taken with different settings.

The Sony A57 produces images of excellent quality. ISO 100-800 is noise-free, while ISO 1600-6400 produces more than acceptable results, and even ISO 12800 and the fastest setting of ISO 16000 are OK for emergency use. More about image quality of Sony A57 you can read on website. The experts of this website conclude:

 While the A57 may be bigger than the A55 model that it replaces, and it loses its predecessor’s GPS functionality, in most other ways it’s clearly a better camera, so much so that it even competes with the more expensive and very similar A65 model. There’s not too much at all to dislike about the new Sony A57, and we can easily highly recommend it as a very capable and full-featured camera that won’t break the bank.


The Sony A57 has a ergonomically-shaped rubberised front grip that is very comfortable and pairs nicely with the neatly curved, rubber-clad rear thumb pad to provide a firm purchase. More about build quality, handling and performance of Sony a57 you can read on website. The expert of this website say:

Throw in a fast, highly-accurate full-time Phase Detection AF system and great image quality, and it’s not difficult to see why we have plenty of praise for Sony’s latest innovation.
