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).

  • Eliminated sensor dust-and-oil spot issue from D600; Great controls for amateur or pro; Comfortable ergonomics and weight; Excellent image quality and low-light performance; Very good dynamic range; Excellent battery life; Built-in lens correction.

  • Not drastically different from D600; Moire with certain subjects; Auto WB still too warm in incandescent light; Slow AF in live view mode; Aliasing in videos.
