Take an air pump to Nikon’s D50 and start inflating, then surgically remove – and adjust – a large 
dollop of kit from the Nikon D200, mix in a smidgen of the Nikon D70s, stir briskly and you get … a Nikon D80.
The D80’s lineage builds on the base of the D70 (and of course the D70s) and some of the D50 and D200 for good measure; the new camera is a very nice mix of the old and new. It keeps (almost exactly) the control and handling of its predecessors with additions such as the user friendly and programmable FUNC(tion) button and nice big top plate data LCD, while including a host of new kit and features that make it even better than its undoubtedly excellent siblings.
The camera’s new 10.2-megapixel (effective) resolution CCD is of the same DX format of the earlier models but that extra resolution makes it much higher resolution, ideal for even larger prints or cropping into images for example. It sits in front of a new image processor designed for this camera. Nikon D80 DLSR digital camera Review - Pocket-lint.co.uk
