The Nikon D800 has had much of its mystery taken away after a leak of details and photos through Brazil. The full-frame DSLR will shoot at 36.3 megapixels, ZTOP saw, and will take a very different approach than the 16-megapixel D4. In return for more than double the resolution, it would have a smaller normal ISO sensitivity range of ISO 100 to 6,400 and a lower maximum ISO as a result, most likely the 25,600 of the D700.
