Does anyone here have experience with multiple medium format systems? How does the Mamiya RZ67 110mm f/2.8 compare to the Pentax 67 with 105mm f/2.4 ? Another potential option is Hasselgay 500cm with 80mm f/2.8 but 6x6 and the camera in general seems very hard to work with. RB and Bronica systems look awesome but they are a stop slower. Boomers have opinions online, I don't trust any of them because they seem retarded. Mostly want to take environmental portraits of friends when we go out. i don't mind carrying heavy things.
Some MTF measurements here:
