This filter is the rotating version, 63 Polarizer, which fits the 38mm Biogon and the 50mm and 60mm Distagons, among others. Hasselblad designed this filter to rotate and incorporated a tiny little "pimple" on an inside rotating ring whose purpose is to "remember" the polarization position when using this filter on the non-reflex Super Wide. The glass is perfect. The outside mount rotates smoothly. I will include a non-Hasselblad filter case.
Ingenious and hideously expensive when new.
