Since I posted this, I found a older post in regards to replacing the screens on a AFDII and possibly having to have Mamiya recalibrate the focus. Coming from the world of 35mm I find that hard to believe especially since Mamiya makes interchangeable screens for the AFDII.
What are the experiences of others in regards to swapping out the screens, and maintaining focus/or having to have the camera recalibrated for the new screen.
