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.

  • Read our Olympus E-M1 Review

  • Very compact body fits in a pants pocket; Zoom lens is both brighter and further-reaching than anything offered by its enthusiast compact rivals; Selfie-friendly tilting LCD monitor; Intuitive touch-screen interface; Very good image quality for its class; Wi-Fi connectivity gets photos on your phone

  • No electronic viewfinder; Soft corners at wide-angle; Flare issues and fringing shooting wide-open; Weak performance when shooting raw files; Tendency to underexpose in low light; Limited battery life
