I went to person's shop to collect a B+W CPL filter. It is a person doing mass sale here and I shall not mentioned who.
I did not accept the filter because there are dust particles on it. But I cannot remove the filter and the stepup ring (52-77mm) after testing it. Now the filter is still with the owner. I think he managed to remove the particles.
Anyway, the ring seems quite hard to remove the filter. And the CPL got another movable ring in between Anyone got similar problem? How do you remove it?
Which direction is to unscrew? Thanks!!!
