When it was released in 2007, the Nikon D3 caused a lot of excitement. Nikon's first full-frame ('FX format') DSLR, the D3 was capable of shooting at ISO settings up to 25,600 - unheard of at the time. Although it became rightly famed for its bar-raising high ISO performance, the D3 also boasted a host of improvements over the DX-format D2XS, including 14-bit A/D conversion, a new standard image processor, a new shutter, new 52-point auto focus sensor, AF tracking by color, nine frames per second continuous shooting, dual compact flash support, DX lens support (albeit at lower resolution) with automatic cropping and a 3.0" 922,000 pixel LCD monitor.
