If a Lens is properly shimmed, and the focus is not accurate across the entire range, it means the focal length deviates from the calibration standard of the rangefinder. Use the formula EFL=(FL1*FL2)/(FL1+FL2-D) to compute the required change in distance between the front and rear groups of the lens, then adjust the main shim. Works for me.
