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

  • Great image quality especially from RAW files; Excellent dynamic range for a Four Thirds sensor; Very good high ISO performance; Realistic colors and excellent hue accuracy; Built-in Wi-Fi with remote control and sharing features; Improved HD video; Lightweight and very portable; Built-in pop-up flash; Minimal EVF lag time.

  • Contrast-Detect AF struggles with small and low-contrast subjects; Mediocre battery life; No external microphone or headphone jack; Mediocre burst speed with continuous AF; No weather sealing; Heavy-handed high ISO noise reduction.
