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.

  • DSLR image quality & resolution in a mirrorless body; Higher-res 24MP APS-C sensor; Much improved AF performance; Better ergonomics with full PASM dial; Built-in Wi-Fi & NFC; Tilting LCD.

  • No built-in EVF; Limited native lens selection; Slow burst mode; Shallow buffer depth with RAW files; No 60p video frame rate or 4K video option.
