I'm looking for a quality 77mm UV filter to protect my new Nikon 80-200 F2.8. I'd prefer to spend <$60 on a quality filter. Here the filters I can obtain within my price range: Hoya Pro1 Hoya HD High Definition (how much better is this filter than the Pro1?) B+W MRC filter (same price as the HD) Kenko Super Pro MC Which would provide the highest degree of protection while preserving image quality? Since I am using this lens on a 1.5x body, thinness is not an issue.
