At DXO, lenses are rated to a camera. I'm about to get a D610. I have some older lenses, AFD, AFS, etc. When an older lens is listed at 12MP, 9MP, 16MP, or whatever with this camera, I'm wondering what MP rating is necessary with the lens/camera combo to make sharp photos/prints up to 11x14. Not sure I'm asking this correctly, hope you get the point I'm trying to make. Trying to find out if my lenses will work well. 17x35, 80x200 AFS, 85AFD, 105AFD, 50/1.8AFD, etc. Thanks much, I'm fairly confused.
