Although ergonomically, the D7000 is a very close match for the D90, its overall 'feel' is considerably more serious, thanks to a magnesium alloy body shell and slightly thicker rubber coating on the hand grip and rear of the camera. At 16.2MP the D7000 offers the second highest resolution of any Nikon DSLR, behind only the 24Mp D3X. All of these pixels are packed onto a newly developed CMOS sensor, which offers a 'standard' ISO span of 100-6400, expandable up to the equivalent of ISO 25,600. The new camera boasts a 39-point AF array with 9 cross-type AF points and works in collaboration with a new 2016-pixel RGB metering sensor to allow 3D AF tracking.
