Look for an adjustment screw that changes the rate at which the rangefinder mirror pivots. If necessary, you can pull off the whole rangefinder assembly to inspect the geometry of the rangefinder mechanism from underneath. Once you find the right adjustment screw, you have to make small trial-and-error changes until both close focus and infinity focus are accurate. A magnifier and groundglass at the film plane are needed to check that RF focus corresponds to film plane focus. |
