I have two MC lens's, 58-1.4 and 55-1.7, both Rokkor The front elements are trashed on both, some problem with cleaners etching the coating I guess. The rest of the elements and mechanics are in great shape. I suspect the coating on the front element (rear surface) had a different coating then the other groups.
What can I use to replace the front elements??
