Review Excerpt

  • High quality images with lots of detail; Excellent graphical user interface is fun to use; Smart implementation of WiFi makes it relatively easy to share photos wirelessly.

  • Designed so much like a DSLR you may wonder why you shouldn't get a DSLR instead; Some performance issues, particularly slow buffer clearing and shot-to-shot speed; Initial WiFi set-up can be confusing.

  • 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.
