Ok; I really did not tighten the frackin polarizer filter onto the UV filter hardly at all. And now, they are like married. I get them off the lens, but can't unscrew them from each other. UV filter was on the lens first, I was at the Mill Pond taking H20 picts so wanted to use my newly purchased polarizer, screwed it on top the UV filter. (my 1st mistake? Should have taken off UV and then put polarizer on?) I know others here might have done similar in their noob days, so simple advise on getting them apart is appreciated. I've tried with my hands, then I've tried one of those rubber jar twisters to hold one, still can't get apart. I'm afraid to put into a vise, even so slightly, as to damage/crack glass. Yea, someone will say "another good reason not to use a UV filter", ok, I typed it for ya.
