Hey friends! Now that I started using filters, I've noticed something terribly annoying... My filters only fit 1 of my 3 lenses! I have a 18-55, a 75-300, and 50, and my 58mm filters only fit my 18-55. What can I do, if anything, to buy just a large filter and use it for any of my lenses? Should I just buy large filters and then buy adaptors to fit smaller lenses? How do you accomplish this without buying a filter set for each lens size?
