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

  • 20MP sensor; Better per-pixel sharpness; Very good, slightly improved dynamic range and high ISOs; Stellar 4K video up to 60p with no crop; 6K Photo; Dual UHS-II SD slots; Good battery life for its class.

  • Buffer is deep, but slow to clear; Expensive; Menus still confusing; No optical low-pass filter means greater risk of moire; No built-in flash.
