Originally posted by pentaxfall Thanks for the explanation. I wish filter makers explained all this. Few weeks ago I was trying to decide between "Clear" v/s "UV/Haze". Read the FAQ on B+W site and it was not helpful at all. Hiding information makes me doubt their integrity and also the claims they make about superior quality of their product.
Finally in a dogmatic style I purchased "Clear" filters.
"Clear" are probably for lens protection only (but should be a well coated filter to prevent reflection issues) if that's what you're after, but putting a UV barrier in there will do no harm.
