sharpness is a combination of contrast and resolution.a clean filter won't affect eitherbutsometimes.filters can pick up a little surface fog,affectingimagecontrast.just make sure your filters are really cleanbefore using them.mine fog up from being kept in foam-padded jewlery containers and need occasional cleaningwith glass cleaner.
