Recently I've started to shoot a lot of color in MF and LF, and I have a cheap Rokunar polarziser that fits most of my lenses, but it is a POC, with a decided blue tinge. I've noticed that there are a lot of new polarizers, from Hoya and others, with special anti reflection coatings and anti-scratch coatings, but I have no experience with them. I'd prefer a neutral filter, but if not slightly warm is better than slightly cold. Any suggestions? My largest diameter lens is my 120 F8 super angulon with 82mm threads. 67mm would fit most of my other lenses.
