Review Excerpt

Same sensor and processor as professional D4; Great image quality; Arguably the best available-light shooter in its class; Handsome, retro styling; Weather-sealed design; Big, clear full-frame viewfinder; Excellent battery life
Expensive; Bulky, yet handgrip is quite modest; Some controls are clumsy; Plastic body panels don't gel with retro aesthetic; Autofocus isn't in the same league as image quality; No AF assist lamp; No movie capture; No portrait grip; Single card slot
