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.

  • Same sensor and processor as professional D4; Great image quality; Arguably the best available-light shooter in its class; Handsome, retro styling; Weather-sealed design; Big, clear full-frame viewfinder; Excellent battery life

  • Expensive; Bulky, yet handgrip is quite modest; Some controls are clumsy; Plastic body panels don't gel with retro aesthetic; Autofocus isn't in the same league as image quality; No AF assist lamp; No movie capture; No portrait grip; Single card slot
