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 use the new XQD memory cards.
The Nikon D4 is aimed at sports and action photographers and photojournalists.
