I am curious what you base this claim on for a filter. Have you done tests your self, or do you have pointers to test that others have done that show the image degraded by, say a single (actually double, one each side) coated filter, such as Heliopan 'standard' coated filter vs any of the 'other' multi-coated filters? Or is this just hear-say and speculation?
