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.
