I have trouble focusing, and I purchased a magnifying eyepiece for the Pentax 645, because I missed focus so often on that first roll. When I went to remove the threaded OEM eyepiece to install the Pentax specialty eyepiece - the old one would not budge. I took the rubber bit off and was confronted with white crystals of corrosion. No amount of cleaning or oil would free it. I found a video of someone repairing the eyepiece - so I got to see how deep the threaded brass ring the rubber had been attached to was - then sawed through the ring with a jewelers saw. "PING" - It literally flew off - being under so much tension. Hopefully, this will result in more keepers. One more frame from the first roll of 30+ year old Verichrome Pan. I had a lot of difficulty focusing my Mamiya 645 Pro TL which is why I switched to Hasselblad H1. These cameras really are harder to focus than I imagined.
Interesting.
I have both Pentax 645N and Mamiya 645 Pro.
The 645N have auto focus so I don't pay any attention on it , but I have no problem to focus my 645 Pro.
