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

  • Phenomenal resolution and detail; Great high ISO performance; Rugged, weather-sealed body; Huge, bright viewfinder; Fast autofocus works well in low light; Swift performance for a medium-format camera; Good battery life; Shoots Full HD video

  • Quite bulky compared to an APS-C or full-frame DSLR; Autofocus points clustered near center of frame; Most lenses aren't weather-sealed or optimized for digital; Prone to aliasing artifacts (but so are most high-end cameras these days); Attracts a lot of attention from passers-by
