Review Excerpt

  • Small, compact body with excellent focusing and exposure capabilities; Newly enhanced touchpanel LCD screen makes image capture and review a joy; Excellent HD video recording quality.

  • Some controls difficult to access; Too easy to activate menus and options while shooting; Lack of a microphone-in jack limits video recording usefulness.

  • Fantastic image quality; Improved dynamic range over its predecessor; Very good high ISO performance; Much improved real-world AF performance; Class-leading burst rates, even with RAW; Improved 5-axis in-body image stabilization; Better 4K video quality; 1080/120fps video; Dual card slots; Significantly better battery life.

  • Expensive; Menus still confusing; UHS-II support only on one card slot; No optical low-pass filter means greater risk of moire; No built-in flash; Buffer clearing still slow despite UHS-II support.
