I have 3 step up rings, all end in 77mm size. As of now when I go to store my camera/lens I have to take off the polarizing filter because I don't want to scratch it. Are there any 77mm caps that work with lenses that have polarizing filters on? Or do I have to take off the PF off each time?
Any 77mm lenscap should fit on your polarizer (unless it's one of the 'slim' models that don't have any front threads), just like it would fit a 77mm-diameter lens.
