It looks like Jim Buchanan did the conversion on this one (nice work!), though AFAIK he doesn't like to do the retaining-ring reduction.

Yes, I am very conservative when it comes to rear element housings. I have successfully reduced a few, as pengland has described.
When I did this work, I also had the other version of Minolta 35/1.8, in for a EF back. That one, I turned down the rear element until the glass surface was just barely protected from the swinging mirror by the retainer rim. That's where I stopped and the mirror would still make contact at infinity. It appeared the 2 versions had the same rear element position, so I didn't make much of an effort on Patrick's. When we're talking .001s of an inch, I get nervous, and the manufacturing tolerances on top of that.
The rear element may unscrew without taking the back off. Otherwise, the 4 screws could be removed. Be aware repeated unscrewing of the back screws could weaken the threads.
