Review Excerpt

  • Excellent still image quality for its class; Fantastic, highly-detailed video quality; Superior video recording chops with 4K video (both Cinema 4K and Ultra HD); Responsive all-around performer with great AF performance and burst shooting; Rolling shutter is minimal with 60p and 30p video; Splash- and dust-proof magnesium alloy body; Built-in Wi-Fi with NFC.

  • High ISO performance not as good as some APS-C models (IQ drops quickly past ISO 3200); Overall still image quality not significantly better than the GH3; Sluggish buffer clearing with RAW files; Rolling shutter noticeable on 4K video; Not as compact as most mirrorless cameras.

  • Phenomenal detail and "depth" at low ISOs; Extremely high resolution; Incredible image quality for the price and size (at low ISOs); Fast x-sync speeds; Unique design is unconventional but comfortable and balanced.

  • Poor high ISO performance; Very sluggish buffer clearing; Poor low-light AF; No built-in flash; Very limited third-party RAW file support; Bundled Sigma Photo Pro RAW software is slow and buggy.
