One good solution to potential binding is to use filters with brass rings rather than aluminum.

The binding problem arises when you have an aluminum part threaded into another aluminum part, as happens with most filters.

B+W and Heliopan make brass-ring filters. There may be other companies. I use B+W filters.

nb B+W is a German company, not to be confused with b&w (erroneously B&W), which refers to flack and white photography.
