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

Large Four Thirds sensor is impressive for a camera this small; Shares sensor and processor of GX7; Excellent image quality with class-leading high ISO performance; Responsive all-around performer; AF system is fast and accurate; Easy to use and responsive touchscreen; Built-in Wi-Fi with remote control and sharing features; Lightweight and pocketable design makes it easy to carry everywhere.
Can be awkward to use with larger lenses; Rear dial is easy to accidentally press; Lacks a hot-shoe for EVF or external flash; Weak built-in flash; 1/50s flash sync; No 1080p60 video; No external headphone jack or mic input.
