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.

  • The most compact APS-C camera on the market; Bright, sharp 28mm f/2.8 prime lens with almost no distortion; Excellent image quality; Extremely customizable; Fast autofocus; Strong built-in flash plus hot shoe.

  • Fixed prime lens is not for everybody; Crowded and small controls; Burst performance is limited; Muted colors and cool white balance; Has issues with moire and false color.
