I just got a nikkor 24 f/2.8 ais. Glass looks great, focus is buttery smooth, the aperture ring turns fine when it is not on the camera. However, when I mount it, it needs more force than my other ais lenses, is more difficult to remove but most problematical, the aperture ring is very difficult to turn when on the camera. My other ais lenses work fine - no issues with turning at all.
I've tried it on an F3, FM and N90s. No problem with any other lenses on any of the cameras.
It seems if I could shave off 1mm of the aperture ring, it would be fine. (I am not about to do that.)
Any suggestions for a fix?
