Nikon D2X digital single lens reflex with 12.2 megapixels.

The D2X uses a DX-format CMOS 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 line-up until the D2X. The camera supports the sYCC colour 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/millimetre (90 lp/mm), 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 up to 8 frames per second (vs. 5 frame/s at full resolution).

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 (pixel pitch) 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. (wikepedia)
