Review Excerpt

  • Professional quality video in a compact body; Still image quality ranks with the best mirrorless models and even some prosumer DSLRs; Fast autofocus; Rugged, weatherized camera build; Reasonably priced for its advanced feature set; Large selection of high quality lenses.

  • Not as compact as most mirrorless cameras; Live View not available during high speed bursts; High ISO image quality and dynamic range not quite as good as top APS-C cameras.

  • Read our Panasonic GH3 Review

  • 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.
