Review Excerpt

  • Excellent, tank-like build quality; First-rate ergonomics a pro would expect; Superb performance with confident autofocus; Great image quality; Big, bright viewfinder with 100% coverage; Excellent battery life; Doubles as a powerful video capture tool

  • Fairly minor upgrade over the D4; Image quality improvements apply only to JPEG; XQD card format isn't broadly accepted; Consumer-friendly default JPEG processing may turn off some pros; Body is large and hefty (but that's normal for pro gear)
