  • Large Four Thirds sensor is impressive for a camera this small; Shares sensor and processor of GX7; Excellent image quality with class-leading high ISO performance; Responsive all-around performer; AF system is fast and accurate; Easy to use and responsive touchscreen; Built-in Wi-Fi with remote control and sharing features; Lightweight and pocketable design makes it easy to carry everywhere.

  • Can be awkward to use with larger lenses; Rear dial is easy to accidentally press; Lacks a hot-shoe for EVF or external flash; Weak built-in flash; 1/50s flash sync; No 1080p60 video; No external headphone jack or mic input.

  • Read our Panasonic GM1 Review

  • Vastly improved burst speeds with deep buffer; Great performance with very fast autofocus; Very high resolution gives lots of detail in good light; High ISO noise levels much better than most pocket camera rivals; High-quality 4K video with uncompressed HDMI out; Super-fast High Frame Rate video; Same great pocket-friendly design.

  • Pricey for a compact camera; JPEGs can look over-processed at higher ISOs; Lens doesn't offer as much telephoto reach; Battery life not as good as predecessor; 24-70mm-equivalent lens can feel limiting.
