For the past few days I've been thinking of selling all my Mamiya stuff, an RZ67 with a 65/110/180, 4 backs, Prism II and a 645 pro with a 65/80 and 2 backs and just getting a Mamiya 7II with a 80mm. I've looked at all of my past work and realized that all of my photography is done at the semi wide and normal ranges. I don't shoot closeups and rarely if ever changed film types mid-roll. The RZ is what I shoot most of my personal projects on and the 645 is my travel camera that I take everywhere. I feel that a 7II would be a lighter and smaller option that will give me the same if not better quality across the board from projects to travel. Plus its easier to lug around in a back pack.
