No, don't give up the Mamiya 6. I'm assuming that you have the modern Mamiya 6. I own both the Mamiya with its 3 lenses and a Fuji GF670. They are so different in handling that you really can't compare them. The Mamiya is my favorite for fall and winter because you can collapse the lens into the body and carry the camera under your coat and it's ready to go in an instant when needed. The fuji is much more fiddly to get ready. I like both cameras but I would not give up my Mamiya 6. ---jb
