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).

  • Absolutely incredible value; Includes a stabilized kit lens; More versatile than a fixed-lens bridge camera; Comfortable body with good ergonomics; Great image quality; Good autofocus performance; Decent battery life.

  • Feels a bit plasticky; Slow burst shooting with limited buffer; Sluggish to power on or switch modes; Low-res EVF and LCD monitor; Can't review images using EVF; No video output; Weak flash; Battery charges in-camera.
