Nikon has traditionally come out with 2 series of cameras. The X series which were with high resolution meant for landscaping and the H series, with high speed meant for sports. This the latest version of the X series, the Nikon D3 X. Its counterpart in the H series came out in 2007.
Although it is difficult to tell one from the other based on appearance, the D3 X has CMOS sensor with a resolution of 24.5 mp. This leads to lower sensitivity and lesser speed of only 5 frames per second for continuous video photography.
While both D3s support DX lenses, the D3 X view finder automatically masks 10.1 mp with the DX lens where as for the D3 H it is 5.1 mp. Both the D3s have 12 channel read out and 14 bit A/D conversion. The image processor for both the D3s is the Expeed image processor which has been optimized for the respective D3 ‘s requirements. While the D3 H can auto focus by color and has about 20 settings of the lens, the D3 X has an auto focus sensor, the Multicam 3500- FX. The D3 X uses an AE and AF sensor for scene recognition.
The D3 X is a high end product and is obviously targeted at the professionals and is a good $1500 more than its nearest rival, the range of the Canon 1 Ds.
