hi there,just want to talk about the B+W filter
now i m tring to get one CPL for my canon 17-40,seems got so many types of the polarizer filter,MRC CPL,SLIM CPL,NON SLIM and KSM CPL. just want to know the difference between the ksm cpl and mrc cpl,which one is better?anyway for normal player,is it necessary to pick up such a expensive cpl? the price i think is the most expensive one among all the B+W polarizer filter
hope to learn from your,thks a lot
