I have a little Oly 35RC. It works fine, but the readout of the aperture in the viewfinder is misaligned. When I set it at f22 I see the needle settling at the f16 dot in the finder, when I set it at f16 I see f11, etc. Can the be fixed? It is not much of trouble and it works in Auto well, but I would like to fix the readout too.
