True. But B50 filters are scarce used (especially in good condition) and both scarce and expensive new. I have a couple for my C lenses, but rely on a B50 to 55mm adapter.

I do like the H'blad hoods. They mount "outside" and independent of the filter mount, so usable with my adapter or B50 filters. And presumably carefully matched to the angle of view of the lenses.
