Hi, I have a nice Ysarex 210mm F/4.5 in Compound shutter in good shape. The only problem is that aperture ring is stiff. It works but it is nail hurting to adjust the aperture. Anybody having the same issue?
Edit: immediately after posting this I tried to put a couple of drops of lighter fluid under the aperture ring plate at the back of the shutter and it seems to have solved the problem. Thus no need to open the shutter.
