Review Excerpt

  • Superb still and video image quality; Powerful, fast, and accurate AF system with loads of cross-type points, loads of configurability and great frame coverage; Rugged, weather-sealed body with great control layout and user-interface configurability.

  • Dynamic range is limited by noise in deep shadows; Somewhat heavy-handed noise suppression and sharpening at default settings. (Shooting RAW avoids both.); No AF illuminator.

  • Superb image quality at low, moderate ISOs; Improved high ISO performance; Fast continuous shooting speeds; Very impressive hybrid autofocus; High-quality 4K UHD video; Rugged camera body.

  • Multi-selector joystick can be awkward to use; No EVF live view at fastest burst rate; Buffer clearing is slow with no UHS-II support; 4K UHD video isn't as full-featured as E-mount counterparts.
