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

  • Rugged and waterproof camera body; RAW image capture; fast f/2.0 maximum aperture; fun shooting modes; fast AF speeds for its class.

  • Heavy noise reduction, even at base ISO; no continuous RAW image capture; underwhelming video performance.
