Hey guys. I just recently bought a Mamiya 7 online and the 80mm separately. When I first got the camera it was way out of calibration, so I sent it back to them to calibrate it. Got it back again, put my new lens on... still wrong. So I brought it to a local repair shop with a good rep to do it. Finally it looks nearly right! But I can tell the infinity adjustment is slightly off, and I'm having some major trouble focusing this thing. I have never owned an RF before, but I have 20/20 vision and I do understand the concept. But practically any time I try to put something in focus, it takes me 20 seconds or so to figure out if it really is in focus. I have to keep going back and forth to make sure I'm in the right spot, and it never looks obviously very sharp to me. Especially when I try to take a picture of something lying on a table from an angle, like a piece of paper. I'm relatively close so I know I've got to be more precise, but even if I concentrate on one part of the paper I want to put in focus, it sometimes seems like things never line up. Almost like what was wrong before, where the vertical adjustment was way off and the patch image would always be a lot lower. So before I give it back to the repair shop to try again, do you guys have any suggestions as to why I'm having such trouble? The main reason for my concern is I had heard rangefinders were supposed to make for very accurate focusing, and I can't imagine being accurate at all if this is the way it's supposed to be. Thanks, Joe EDIT: By the way, I was just going to shoot a test roll and see how things came out, but I didn't think I was having any luck because certain things I could never get to look like they were in focus.
