All you Nikon manual focus crew: I just picked up a literally BNIB FM3a. I need a +3 diopter correction. Leica M's cost 109$ and I don't know if it would fit the FM3a. Nikon's are like $20 bucks or so. Any recommendations? TIA
I'm lucky enough that the diopter works for me. I would go for the Nikon. It's much less expensive and you know it will work. Why pay for the Leica name if you don't have to?
