Review Excerpt

  • Solid alloy body with true twin-dial design; Smaller, lighter, and cheaper than most direct competitors; Excellent image quality, even when compared to interchangeable-lens cameras; Numerous accessories expand upon its capabilities.

  • Fixed prime lens is not for everybody; Ergonomics could be better; Performance is spotty; Built-in flash is rather weak; Battery life is quite modest.

  • 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.
