Hi to everybody,
I don't know am I writing this issue to the right section of the forum; if not, please, move it.
I have some kind of problem with Kenko CPL filter (52mm). It seems, when I turn the filter while holding it in the hand, at some point one can see a little line which indicate that the process of making hasn't been finished, within a certain layer, through the end.
Am I going to have a problem with images (I did take a photo towards a blank white wall but couldn't see any failure) or should I change it?
Kind regards.
