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.

  • Amazing screen; Good image quality; Offers more control; Virtual half-press on shutter if desired; easy uploads to social media.

  • Occasional signal trouble; Banding in Macro mode; Design is so slim it's sometimes hard to hold; Muted color.
