ic, what I did was I had one body, body "1" that is perfect with each lens, up close, at infinity, in between. When the cameras came back from Mamiya the two cameras agreed at far focus (beyond 10ft) but not closer than 10 feet. My test was I focused camera "1" on something close at 7' (knowing this focus is correct), I took the lens of camera 1 and put it on camera 2 (without moving the focus ring) and the patches did not line up. So from there I adjusted the rangefinder until the patches lined up. But now camera 2 will not line up focus at infinity. It's almost like a trade-off. Do you want to focus up close accurately or far away with camera 2? And it shouldn't be like this.
