Best Circular Polarizing Filter

Years ago I threw out all of my Hoya filters because there were sample variations and they were all difficult to clean....perhaps the Pro1 is improved but personally I've lost faith in them.  Now I only use MRC filters by B+W which may be slightly more expensive but well worth it,...... no image degradation, premium German Schott glass and brass mounts which minimize binding.

If you are shooting in extreme conditions, i.e., high humidity, extreme temperature variations, etc., you might consider the Kaesemann option which provides better foil sealing.
