Hello All,
Was hoping to get some help with my Mamiya 7. I have an Mamiya 7 and the 80mm and 150mm lenses. A few months back I switched lenses and put the 150mm on and realized that the rangefinder lost calibration with that lens. I did some digging and found that the lenses can lose calibration at times so I just stuck the 80mm back on since I don't use the 150mm too much.
A bit later the camera lost calibration again, both vertical and horizontal so I adjusted the calibration myself using the 80mm and focusing on the other side of a valley, roughly 5 miles away. This worked for a while but on a trip a few days ago I pulled out the camera and the vertical alignment was way off again.
I was wondering if anyone knew how to keep the alignment from wandering or in anyone knows of a good shop that could adjust for me and potentially even adjust the 150mm so I can use it again.
Thanks!
