Review Excerpt

  • New carbon fiber body is light, compact and very comfortable; Same excellent image quality as the flagship D500; Quick 8.2 frames per second burst shooting with generous buffer; Very fast, accurate autofocus; Tilting touch-screen display; Very good battery life; Records ultra high-def 4K and 60fps Full HD too.

  • Only a single flash card slot; Doesn't support portrait / battery grip accessories; No rear infrared receiver any more; non-CPU AI lenses will be manual only; 4K video comes with a heavy crop; Movie AF is prone to hunting, Extended ISO sensitivities are a gimmick.
