Cameras with longer battery life can take more photos before exhausting their batteries.
Special note: The measurement standard for battery life stipulates that if a camera has an internal flash, it must be used for 50% of photos taken. For this reason, comparisons of one camera with an internal flash to another without will not be comparable
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)
Fantastic image quality across the board; Excellent RAW dynamic range; Superb high ISO performance; Functional and user-friendly body; Robust weather-sealed construction; Detachable EVF; Tilting touchscreen; Very good lens quality.
Slow AF speeds; Performance can't compete with high-end full-frame cameras; Limited native lens selection so far; Expensive accessories; Unimpressive JPEG dynamic range; 1/125s maximum flash sync.
