chris_david Posted August 16, 2004 Share Posted August 16, 2004 I bought a beat up Canon P and need help adjusting the rangefinder. I know how the adjustment should work and have sccessfully adjusted the rangefinder on several LTM camera before. The problem is the RF patch is always too low no matter how much you turn the ring. At its best the patch is about 30% too low. I'm guessing I have to take the top cover off and adjust or replace something inside. What is the next thing I should do?

john_shriver Posted August 16, 2004 Share Posted August 16, 2004 When I replaced the RF mirror in my Leica IIIa, I found I had to shim the bottom of the beam-splitting mirror to get it within the range of the rotating wedge prism. (Perhaps Leica didn't make this mirror quite right, and the two sides weren't quite parallel?) You certainly will need to pull the top, and see if some part in the RF is out of kilter. Perhaps there is a coarse adjust on the moving mirror. Link to comment Share on other sites More sharing options...
