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.

  • Exceptionally detailed and uniquely beautiful image quality at low ISOs; Fast, sharp 28mm-equivalent lens; Simple, straightforward controls match camera's simple, straightforward (street photography) goals.

  • Fixed-focal-length lens; Image quality deteriorates significantly at ISO 800 and above; Overall sluggish performer; Falls short when capturing JPEGs; Terrible VGA-only video quality; Very poor battery life; No built-in flash.
