Since one ideally uses a polarizer at a right angle to the sun, I have never been certain that adding coating to a polarizer accomplishes very much. I believe that Pentax does not add SMC coating to their polarizers, while they add SMC coating to nearly everything else that light goes through.
Tiffens and Hoyas will usually give you good quality at a decent price. For coated filters I prefer Pentax, B+W, or Heliopan. Joe -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
