^I've played around with various versions of the Rokkor 58, the rear retaining ring is solely to keep the rear element from falling off the lens. It would not affect your ability to covert it back and forth to different mounts.
Filing it down would give some additional clearance, but it still catches on the mirror at inifity. I modified a one a while back to test on my brother's 6D, with a lot of work, it cleared the mirror at 30 meters. That was the best I could get it without shaving the mirror, it was tempting even though...Show more →
haha never done a mirror shave.
just curious, if you shave the mirror, that part of the mirror will appear dark in the viewfinder?
i have no idea how the shaving is done.
I'm not going to attempt that on my kodak slr/c, maybe I will buy a 5d and do it
