The range finder focuses just as accurately no mater what the aperture is set to. There is no mechanical connection between the range finder and the aperture on any lens mounted to a CL. However, because the CL's range finder base is shorter than the M series the accuracy of the CL's range finder is somewhat less than the M's. Leitz engineers felt that the range finder was not accurate enough to focus a 90 mm lens at apertures greater than f4 because the d.o.p. becomes so narrow. You must remember that Leitz' standards are very high and in normal photography you may not notice the any image degradation from a slightly less accurate range finder. John Shick
