Hang on to the 77mm filters and just buy step up rings to fit your other lenses. Rings can be purchased for under $10.00 - a whole lot less than a new filter. I did that at Christmas - bought the 77mm B+W CPL that fits two of my lenses and is the largest size I need. Then I bought a 67-77 step up ring and a 52 to 77 step up ring so I can use it with my other lenses. As long as you buy a filter that is larger than your lenses, you have no problem. You get vignetting if you try to use a smaller filter than the lens (makes sense - it's opening is smaller than your lens). That's the way to save money and not have to buy the same filters to fit each size lenses.
