Review Excerpt

  • Excellent high ISO performance, one of the best APS-C sensors yet; 6.5 fps burst mode has very good buffer depths; Weather, dust, and cold resistant; In-body Shake Reduction corrects not only horizontal / vertical, but also rotational motion.

  • Default saturation and contrast a bit high; Auto white balance too warm in tungsten light; Fewer AF points than main competitors; Only a single card slot, and no UHS-I card support (slow buffer clearing).

  • Excellent image quality; Improved high-ISO performance; Better JPEG quality; Fast autofocus; Very good subject tracking with real-time live view feature; All-magnesium body construction; 4K video.

  • Slow buffer clearing (no UHS-II support); No touchscreen, Clunky menus; Wi-Fi can be a bit frustrating to use.
