Recently revieved a few Wollensak lens that have the diffusion ring on the front on the lens. The only problem is all seem to frozem or stuck. I need to know which way these should turn, if they should be removerable from lens, if so clockwise or counterclockwise Also need info on frre and lubricating ring to free it up. Any informatiom would be hklpful as I don't want to do any damage because of lack of knowledge. Thanks
