Review Excerpt

  • Top-notch image quality; Great ergonomics in a compact body; Unique on-demand low-pass filtering; Broad sensitivity range; Large and bright viewfinder for an APS-C camera; Dual card slots; Optional Wi-Fi remote control

  • AE Lock button is poorly located; Below-average battery life for a DSLR; Rather dated-looking menu system; Requires a different battery grip accessory than its predecessors; Less third-party support than some rivals

  • 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

  • White balance tends warm under incandescent lights; 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
