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.

  • Excellent high-ISO performance for such a compact model; Smart controls; Small body; Bright lens; 10fps full-res burst mode; Very fast shutter response; Excellent LCD.

  • Lens flare at night; Poor rendering of yellows; Slow flash recycling; Soft corners wide open; Continuous AF mode slow to lock.
