Review Excerpt

  • Amazingly small for a DSLR; Great image quality for its class, including superb low light and high ISO performance; Generous JPEG buffer depth; High resolution.

  • Buffer depths are shallow when shooting RAW; Lacks GPS from the predecessor; No AA filter means it's susceptible to aliasing artifacts.

  • 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.
