The Nikon D4 is aimed at sports and action photographers and photojournalists. With a continuous shooting rate of 10fps, a 20-second burst would yield 200 full-resolution images with full metering and autofocus for each frame. If exposure and focus are locked, the shooting rate can be increased to 11fps.
