I think a 90mm is cheaper because it's the "normal" lens for the Mamiya so they make more of them. It's sad to see that these great cameras and lenses aren't as valued today. I bought my RZ over 25 years ago and it cost a fortune. The upside is that it's cheaper for folks like us that appreciate these cameras to buy them. I work at a university art department and some of the students are rediscovering film cameras. I see them shooting the Fuji 6x7 and Haselblads. There's still hope for analog photography!
