What is the quality like for these lenses? This says the system was discontinued in the 1970s.

I've seen a lot of Mamiya 645 and 67 systems but those were probably from the 1980's and 90's.
I can't speak for the Mamiya Press but the Zeiss Planar 80mm f/2.8 for the Graflex XL is rad.
Good for the time but dated. When your negative is the big it doesn’t matter as much but it’s absolutely not as sharp as more modern constructions. It’s also arguably a step down to use his printed body versus the original Mamiya press in terms of functionality other than reduced weight. Still an impressive design though.
