The D3S features a highly sensitive 12.1 megapixel FX format CMOS sensor that boasts an ISO range of 200 to 12800. The D-movie function offers superior movie capture in stereo (Compatible stereo microphone required) sound and features a Save Selected frame option to speed up productivity. Nikon’s acclaimed 51-point AF system offers high sensitivity in low-light and superb performance when tracking fast moving subjects. An advanced image sensor cleaning function reduces the impact of dust spots and three alternative crop modes enhance shooting flexibility.

Protected by a tough, environmentally-sealed magnesium alloy body, the D3S redraws the boundaries for professional action photography.
