Review Excerpt

  • Exceptional rugged, weather-proof, professional build; Lightning fast contrast-detect AF, and phase-detect AF that makes Four Thirds lenses far more responsive; Tons of useful physical controls with immense customizability; Arguably the best image quality of any Micro Four Thirds camera we've tested to date; Large, sharp, high-resolution electronic viewfinder; Advanced Wi-Fi capabilities, including remote control shooting in PASM exposure modes.

  • Bigger and heavier than many other compact system cameras; Most expensive Micro Four Thirds camera on the market to date; Menu system and customization options have a steep learning curve; No optical low-pass filter means greater risk of moire; No built-in flash.

  • Impressive overall image quality; Excellent high ISO performance; Very good dynamic range from RAW files; Full HD video at 60 fps; Good battery life.

  • Slower-than-average AF speed; 4K video capped at 15fps; Very slow startup to first shot time with new power-zoom kit lens; Sluggish single-shot cycle times.
