Hey guys, I just picked up an Olympus 35RC recently and after shooting a roll it became apparent that the focus was off by a good amount. I got the top of the case off and adjusted the vertical screw correctly, but I can’t get minimum distance and infinity to both be in focus at the same time. I’ve tried almost every position on the nonlinearity screw, but still can’t get it right. Is there a better way of going about getting it in perfect focus?
