Hey guys. I bought my Mamiya 7 a month or so ago and as soon as I got it I noticed it was out of calibration. I sent it back, they say they gave it to Mamiya to be recalibrated, and then sent it to me. I get it back, still can't make the images line up (patch image was higher or lower by quite a bit, can't remember which). So I give it to my local shop, Kurt's Camera Repair, which has a great rep. They calibrate it, and I'm still unsure that it's perfect... it was very hard to focus and I knew the infinity was off a bit. I gave it back and they said it did look like it was slightly out of calibration, so they re-calibrated it and held on to it for a couple days to make sure it wasn't slipping, and gave it back. Anyway, the infinity adjustment definitely still is off a little bit. The lens stops at infinity like it should, but I can always make the image look a tiny bit sharper if I turn it a very small amount back away from infinity. Would this cause a big problem with normal focusing? I'm not sure how these things work yet. The rest seems OK, but sometimes it looks like the patch image is slightly higher than the normal image, even if I can align them side-to-side. It can be difficult to tell once the images are lined up whether the patch is still higher though. Any ideas? Should I try maybe calibrating the camera myself if it's not too difficult? I'm using the 80mm btw. Thanks!
