Review Excerpt

  • Extremely fast autofocus; Pop-up flash and AF-assist lamp; Full HD recording; wisely limited focus for touchscreen; excellent print quality results; removable grip.

  • Larger than some competitors (see E-PL3 if you prefer a smaller camera); strong noise suppression; touchscreen easily activated by mistake; list of options is overwhelming; shoulder strap D-rings are noisy.

  • 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.
