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).
