Focusing problem
Hey Guys,
My mamiya rb67 Pro S is working great, except when I got my scans back the focus was off, it was focusing behind my subject. Also, when i look through the viewfinder I can’t see infinity its just slightly off. I know that the problem often exists in the focus plane, that it’s not well adjusted. So I went to check the screws and make them (equally) tighter, turning them 1/4 at a time. After about a full circle one of the screws gets really tight and i cant rotate it further. The two screws on the left are much looser. Any advice on how to fix it? I cant screw them further in I think.. any help or insights are greatly appreciated!
