I'm lost on this one as far as "63mm filter Size". Which 50mm Hasselblad Lens - specifically, do you have?

My "Carl Zeiss Distagon 4/50 T*" takes a "Bay(onet) 60" adapter -- and Cokin has "Bay 60 adapters (I have one) for their "P" series filters.

There is a "Bay 60 - 67mm" Adapter for use with screw-in filters _ I also use one of those. I think a 63 mm filter will probably vignette. Tiffen, B&W, Hoya - most likely many others - make those.
