That "ridge" wasn't needed on the old Nikkormat cameras as the aperture info was transmitted to the camera via the aperture prong If you remember, you had to turn the aperture ring on the camera to transmit what the maximum aperture of the lens was to the camera. It was a pain......

Scott,
Your reply has me somewhat confused. You said "That ridge is what's needed to operate properly on any Nikon camera" and you replied to me "That ridge is what's needed to operate properly on any Nikon camera." Did you mean that ridge is what is needed to operate properly on any "DSLR"? My 50 mm without that "ridge" operated fine on my Nikkormat film camera. :?:
