Review Excerpt

Improved 20.1-megapixel resolution; Impressive image quality, especially for its price; Fast and decisive autofocus (in most conditions); Very good battery life; Good video quality (Full HD 1080p, though it doesn't support 60p frame rate).
Plastic lens mount; Slower burst mode speeds and shallower buffer than A57; LCD no longer fully articulating; Mediocre kit lens; Electronic instead of an optical viewfinder may be a turnoff for some.
Read our Sony A58 Review

Excellent value for the money; Professional-grade ergonomics; Incredibly good image quality for its class; Solid performance specs across the board; Loaded with features.
Kit lens may not be quite as sharp as previous kit lens from this line; Below average battery life; Somewhat confusing menu systems.
