I don't think that the camera does anything with the info, though, except enter it into the EXIF data and probably use it in the metering programs.All that is entered is the focal length and maximum aperture of the lens, and that value is then stored for future use. You can have up to 4 different lens max. apertures for the same focal length using custom menus. I see no reason that Leica could not have stored a list of the lenses supported by in-camera processing in a menu for easy selection, though lens "upgrading" probably does supply a small but significant (to Leica) revenue stream. As an aside, it is pretty amazing to use an EXIF viewer (like Opanda for the PC or EXIF Viewer for the Mac) to look at all the data that is recorded for each shot taken with a camera- there is far more recorded than you see with most image viewers. I just learned that the total number of photos taken with the camera is recorded in the jpeg files, along with a lot of other esoteric, equally useless trivia, though it might be useful if you were buying a used camera.
