I can't offer advice beyond what you've gotten. I'll just add that for some reason the combination of my DA 14 and B&W polarizer tend to bind. I now carry a filter remover, and try to remember not to tighten the filter in. Bit of a nuisance.
The B&W's are brass and aren't supposed to do this. I don't have the problem with any other lens/filter combination. Joe -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
