The Nikon D4 is a 16.2 megapixel professional-grade full frame (35mm) digital single-lens reflex camera (DSLR) announced by Nikon Corporation on 6 January 2012. It succeeds the Nikon D3S and introduces a number of improvements including a 16.2 megapixel sensor, improved auto-focus and metering sensors and the ability to shoot at an extended ISO speed of 204,800. The camera was released in February 2012 at a recommended retail price of $5999.95. It is the first camera to utilize the new XQD memory cards.

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.
