Review Excerpt

  • The first genuinely compact--almost pocket-friendly--compact system camera, paired with equally small, interchangeable lenses. Great ergonomics for the size, and it feels like a real camera, not a computer with a lens.

  • Very restrictive lens selection at launch. All but two current lenses have severe limitations in functionality. Performance is sluggish, and image quality trails large-sensor cameras by some distance.

  • Handsome retro styling; Very good image quality and dynamic range, with competitive high ISO performance; Lightning fast autofocusing; Excellent burst speeds (nearly 10fps at full res); Top shutter speed of 1/8000 second; Sharp, bright 17mm f/1.8 kit lens; 3-inch tilting touchscreen LCD with 1.04M dots of resolution.

  • Heavier than some mirrorless models; Weak flash; Below average battery life; No built-in viewfinder (but EVF available in a kit or for separate purchase); A bit pricey compared to the similar E-M5, which offers a built-in EVF and weather sealing at about the same price.
