Hello.
Picked up an Olympus Zuiko 55mm f1.2 in poor shape
Fortunately, the glass only needed a good cleaning. A few very minor blemishes left but very minor.

OK, 2nd problem, the focus ring is not linked to the mechanism. It rotates freely and the lens doesn't focus at all.
I removed the rear mount, hoping I could take the focus ring off and get a look at the problem.
But I still cannot remove the focus ring and now I am not sure if I can remove it at all by going in through the back.

Does someone have a diagram or instructions on dissembling this lens?
