” The Nikon D3 is a digital single-lens reflex (DSLR) camera introduced on August 23, 2007, following the D2 series as Nikon’s top-of-the-line professional grade camera. Unlike its two predecessors, at least initially, the D3 does not have separate H and X variations, such as the D1H/D1X and D2H/D2X, which are optimized for action photography (H) and high-resolution applications (X), respectively. ”
Another important distinction for the D3 is that it is Nikon’s first DSLR that uses a 23.9x36mm sensor, which Nikon now refers to as the FX format. For all practical purposes, it is the same size as the traditional 35mm film frame (24x36mm). Therefore, Nikon F-mount lenses will produce the same angle of view on the D3 as they do on 35mm film SLRs, and there is no more digital “crop factor.”
