I am planning to upgrade my D40 to a D7000. All my lenses are either AI or AI'd. I have read that "data for up to 9 such lenses can be programmed into the D7000." I'm curious how the programming is physically done. Do I sit down once with my new camera and program the data for each of my lenses, then later when I'm ready to shoot, select the lens I'm using from a menu? Exactly what data do I program for each lens? Just the focal length? The focal length and the maximum aperture? What about the programming for a zoom lens, or a Micro Nikkor?
Finally, is the programmed data (as well as the actual aperture) saved in the EXIF metadata?
