Review Excerpt

  • Rugged build; Excellent controls; Extremely high resolution; Dual cards; Surprising high ISO performance.

  • Very large files; Slower frame rate; Custom white balance gives a greenish tint; Battery life lower than D700.

  • 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.
