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.

  • Read our Pentax Q Review

  • Rugged and waterproof camera body; RAW image capture; fast f/2.0 maximum aperture; fun shooting modes; fast AF speeds for its class.

  • Heavy noise reduction, even at base ISO; no continuous RAW image capture; underwhelming video performance.
