Over the years, I've shot Mamiya RBs, RZs, M6s and, currently, M7IIs. I've never needed a repair on any piece of equipment until recently. Two weeks ago, I was shooting one of my 7II bodies when it stopped taking images and its warning light came on. I cleaned the contacts between body and lens, replaced the battery- no good. I sent the body to Mamiya America in New York, noting it had low mileage and had stopped working for no apparent reason. Even though the body is six years old and is well out of warranty, Mamiya replaced the circuit board for no charge and the body is functioning perfectly. More impressive still, Mamiya did the repair pretty much overnight, as I got the body back about ten days after I sent it UPS Ground. That's great service.
