Yes, there is a difference. Filters should last forever, so buy them once and buy one that is intended to last forever, that being the B+W brand and with their XS-Pro MRC models (UV / ND) or Kaesemann (CPL). Being they are intended forever, look for used filters being resold as a way to save money such as KEH, Adorama, ebay or the for-sale here at UHH.
I agree. Those are what I buy, and buy used if I can.
