Unscrewing diopter (M7)
I'm considering buying an empty diopter from Leica for my M7 and having an optician put in the correct glass for me. I'm beyond the -3 to +3 range.
Before buying the diopter, I want to make sure I can free (unscrew) the exisitng diopter.
I - and peope stronger than me - can't budge it. I even tried a pair of small pliers to no avail.
I believe the outer ring of the diopter is rubber and I'm tempted to try to take it off in the hope that if I get to the metal interior I can budge the diopter.
I'm looking for advice on how to proceed. By the way, if I destroy the ruibber ring, will I be able get a new one from Leica?
