The D2X uses a DX-formatCMOS sensor supplied by Sony instead of either a charge-coupled device or the Nikon proprietary LBCAST sensor which had both dominated Nikon's digital SLR lineup until the D2X. The camera supports the sYCC color space. The CMOS sensor used in the D2X has the ability to resolve about nine times more than the human eye. At 90 line pairs/millimeter, the sensor can resolve extremely fine detail. This makes the camera perform exceptionally well when used as a landscape or scenic imager, since it can better resolve smaller detail in distant objects. The D2X surpasses the D2H and its successor the D2Hs by providing 5 frame/s at 12 megapixels, and 8 frames/second at 6.8 megapixels with its high-speed crop mode. In high-speed crop mode, the camera sacrifices pixels in favour of speed and crops the image to 50% of a 35 mm frame to enable continuous shooting at 8 frames per second. It incorporates some other innovations such as refinements of the metering and autofocus systems. At the same time, the camera is able to make use of virtually all of Nikon's F-Mount lenses, including most legacy lenses. It has a rated shutter life of 200,000+ images, which is generally double or triple than less costly cameras. It is one of very few cameras with a built-in "third-eye" which records the color of ambient light, giving the D2X an additional tool to accurately compute the white-balance for each image, instead of relying on calculations based only on subjects within the picture frame. At the time of its release, the D2X had the highest concentration of pixels of any Nikon DSLR made to date. While its resolving capabilities are impressive, the very small resulting pixel size puts the camera at a disadvantage when working in low light by introducing slight noise in underexposed areas. The D2X has excellent noise reduction software built into the camera, so its images reflect the very high quality one would expect from an expensive digital SLR.
Audience
The D2X was aimed at professional users. It replaced the D1X and complemented Nikon's D2Hs camera with which it shares a body. It was a very important model for Nikon given the 3½ years which had elapsed between the D1X and D2X, during which time competitive pressure mounted on the D1X.
Competition
The principal competitive cameras for the D2X were the full-frame Canon EOS-1Ds Mark II and the Canon EOS-1D Mark II N. There was also some competitive overlap between the full-frame Canon EOS 5D and the D2Xs, although they were not direct competitors. An unresolved debate rages about the respective technical compromises of the DX-format sensor and full frame sensors offered in competition with the D2X's DX format. Each format offers advantages and disadvantages which become more or less important in different usage settings. Nikon, convinced that the design characteristics of the DX format are best choice for its customers and target markets, had committed itself publicly to the DX-format sensor and its line of DX lenses is specifically designed for the smaller sensor. This philosophy remained until 2007, at which point Nikon's new generation of professional-level digital SLRs - the Nikon D3 and Nikon D700 - adopted a full-frame sensor. Nikon's D2X was awarded best product accolades for 2005–6 by the European Imaging and Sound Association. Named European Professional Camera of the Year, the D2X's 'extraordinary performance' was praised by the judges.
Nikon D2Xs
Nikon D2Xs is a digital single-lens reflex camera announced June 1, 2006, replacing the professional Nikon D2X. Its improvements over the original D2X include:
Automatic viewfinder masking in high-speed crop mode
Increased buffer capacity to 60 frames in continuous shooting
