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

  • 360-degree spherical panoramas at the click of a button; Puts you back in the moment like no other camera; Good ergonomics and control layout; Great still image quality, and can shoot videos too; Upload panoramas to Google Street View

  • Very reliant on your smartphone or tablet; Battery and storage can't be replaced or upgraded; Handheld shots suffer from Gigantic Hand Syndrome; Hard to get yourself out of the shot; Video image quality is only modest; Interval timer has a long shot delay
