I am about to buy a polarizer filter for my Canon EF 300m f/2.8L IS prime lens (old version, not the new version II). I noticed there seem to be two versions out there of the PL-C 52. Some have the addition WII. They are cheaper and more easily available. I guess it is an updated version of this filter?
My question now is, will the WII version be compatible with my older (non II) telephoto lens? Of course I would prefer to buy the WII, but maybe I have to lookout and try to get one of the older versions?
Thanks and best regards,
