Nikon D3

Nikon answers new dSLR cameras from Canon with its top-of-the-line digital single-lense reflex camera, the 12.1-megapixel D3. The D3 comes with a full-frame CMOS (complementary metal-oxide semiconductor) image sensor, which Nikon has dubbed the FX format.

In its regular mode, the D3 offers sensitivity settings from ISO 200 to ISO 6,400, and if you turn them on, Hi-1 gives an equivalent of ISO 12,800, while Hi-2 offers an equivalent of ISO 24,600.

The D3 has a 3D tracking mode that works in tandem with the 1,005-segment metering system to help track your subject as it moves throughout the frame.

Nikon predicts that the D3 will go on sale in November for about $4,999.95, not including a lens.
