1. Nikon may not like the comparsion to the N80, because there are structural differences between it and the D100. However the image taking system is probably very much like the N80. From all accounts a N80 owner would feel very much at home with the D100. I know I feel very much at home with the D1X because of my continued ownership of the F100. There is clearly F100 heritage in the D1 series.
2. On the Kodak cameras, it says Nikon F5. That is exactly what they are. A digital imaging system has been grafted to a film camera. Rich
