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)
Attractive, retro rangefinder-style design; Excellent still image quality; Great, sharp f/2 35mm-equivalent lens; Overall better operation than the X100S with improved controls and dials; Improved optical viewfinder coverage; Built-in Wi-Fi.
Low-light AF still slow and inconsistent; Video quality still compromised by moire and lack of image stabilization; Buffer depths could be better when shooting RAW.
