Hi Peter, thanks for making and sharing this video. I'm looking to rebuild a Mamiya RB67 I got from a friend. It's missing a focussing screen, cocking mechanism and lens 'was' stuck, bellows are totally trashed and the light baffle flap doesn't flip all the way up. After watching tons of videos on CZcams, I've unstuck the lens and mechanism, figured out how to make bellows and I'm currently working to figure out the light baffle situation. However, I find that there's very very very little resource on CZcams about ground glass for medium format cameras. So I'm looking to make my own ground glass and Fresnel lens combo and would appreciate any tips from your wealth of experience on this subject matter. I'm looking for the most budget friendly and resource restricted solutions, so I'm asking questions like, can i use any Fresnel lens or do I need a specific type? Are there any other devices (like laptop screens) that use similar fresnel lens? etc PS: I have digital fabrication tools like 3d printers and laser cutters available to me and I'm very comfortable designing parts and building things.
Thanks Bro, This is a great great tutorial.
