Review Excerpt

  • 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.

  • Cheap as chips (and with a kit lens!); Quality Sony Exmor Four Thirds sensor; Widely-supported Micro Four Thirds lens mount; Good image quality from raw files; Reasonable burst performance for price; 4K video capture.

  • Poor ergonomics; Controls too easily bumped; Frustrating user interface; Mediocre JPEG image quality; Heavy-handed noise reduction; Unreliable white balance; No raw+JPEG; Buffer is almost nonexistent; Focus confirmation beep happens while still focusing; AF is poor in low light; Laggy user interface in playback; Extreme crop for 4K video; Kit lenses feel cheap; No bundled flash.
