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

  • Very good image quality; Improved dynamic range & high ISO quality over T6i; 45-point AF system; Fast Dual Pixel CMOS AF; Improved buffer depth.

  • Default JPEGs slightly soft straight out of camera; Dynamic range & high ISO still lags behind competitors; No 4K video.
