Nikon D3X

       The Nikon D3X is a 24.5 megapixel professional-grade full frame (35mm) digital single-lens reflex camera (DSLR) announced by the Nikon Corporation on 1 December 2008.[1] The D3X is the third camera in Nikon's line to offer a full frame sensor, following the D3 and D700. As Nikon's new flagship model, it augments the Nikon D3S, Nikon's high-speed professional model, and while the D3S retains advantages in terms of high ISO performance and higher frame rate, the D3X offers a dramatic increase in resolution and image detail.

       The D3S and D3X follow the earlier Nikon D1, Nikon D2H, Nikon D2Hs, Nikon D2X, Nikon D2Xs, and Nikon D3 as the company's top-of-the-line DSLRs intended for professional photographers, which in turn share a lineage with the Nikon F through Nikon F6 series of film SLRs.
