I have here a really nice Minolta MD Rokkor-X 45mm f 2 lens here that is missing the rubber focusing ring. I'm hoping someone here might have one they would be willing to part with, or know of where one could be obtained.
I'm also curious if anyone has any experience with making one. It's a last ditch option but as I'm just planning on using this lens myself, and not ever selling it I'm thinking that a ring could be made. I'm thinking perhaps using that plastic dip stuff for coating tool handles and trying to fill the ring groove to provide a rubber grip. Anyone ever tried something like this?
