Review Excerpt

  • Appealing design; Good grip; Very good image quality; Fast autofocus; Built-in Level Gauge.

  • Small rear buttons; Below-average battery life; Weak flash; Orange and yellow can have greenish cast in JPEGs; Shutter-induced motion blur with 14-42mm X Vario kit lens.

  • 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)
