Nikon D80 slots nicely between the entry-level D50 and the semi- professional/ professional D200, clearly based on the D70 design but also different enough to be seen as a completely other model. It features a ten megapixel DX format CCD (the same we presume as used by Sony in the DSLR-A100), the metering sensor from the D50 and numerous other items taken or modified from the D200.
