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.

  • Captures sharp, detailed photos with its new 24.1-megapixel CMOS sensor, even at higher ISOs; Features a familiar (D5100) but refined body design; Records Full HD video with full-time autofocus tracking; Packs a ton of advanced features into a consumer-friendly body at a great price.

  • Autofocuses a little slowly for its class and struggles at times in low light; Changing some basic settings takes more time and effort than it should; Mediocre kit lens.
