Hello,
I currently own a pentax 67 camera with a broken metering chain. I don't have any intentions to repair it, however I wanted to ask a question to someone who may know the answer. After repairing the chain and replacing the bayonet seat in it's original place, how important is the calibration process of the flange to film back rail distance and would skipping this part of the process have a significant impact on the picture quality?
Thank you
