Got a new rotating polarizer and wanted to give it a quick try, so put it on my 24-84 zoom, which already had a UV filter. When rotating the polarizer it would start to unscrew, so I had to tighten it several times to keep it from fallling off the lens. Now I can't get the polarizer off of the UV filter! I've tried everything I could think of, so I hope you guys have some really sharp advice. I don't have a filter wrench but I do have a bottle cap opener that works great, up to now. The two filters are so small that I can't get a good grip on either. Help!
