The Nikon D3 Professional SLR Digital Camera features the exclusive FX-format CMOS sensor, measuring 23.9 x 36mm, which is nearly identical to the size of a 35mm film frame - thereby eliminating any significant crop factor or focal length multiplier. Images taken with the D3 exhibit exceptional overall quality, broad tonal range and depth, along with extremely low-noise throughout its normal ISO range of 200 to 6400. Furthermore, by setting the camera to its built-in options of Lo-1 or Hi-2, the ISO range of the camera can be expanded to the equivalent of ISO 100 or ISO 25,600 respectively, offering unmatched versatility in practically any shooting situation.
