I've seen alot of Hasselblad B70 filters and bay70~77mm step up rings, but what do you use when you want to use a filter on a bayonet 77 filter ring?Did Hassy make bayonet 77 filters for this and the FE Tele-Tessar 250mm f4?Mark
a series 70 (bay70) filter and/or bay70-to-77mm adapter ring is what you're looking for.
Thanks. It's the Hasselblad terminology that had me stumped as I was thinking that a bay70 would be 70mm, not 77mm.It just so confusing when the lens sheet says B77 but the accessories are B70.
