4x5 backs on an RB67 (for the RH50)

I have 10mm to play with, so 3D printing is a viable option. I can also adjust the screws on the back by tiny amounts in order to get the focus exactly right, so I’m not super worried.

If you can get a ground glass screen to fit in some way, your focus issues are history.

Well, unless you want to focus on the horizon. If the film/ground glass are further away than the original film plane, you'll be locked into focusing closer -- and if they're much further away, you might be stuck with macro images...

I did get a prototype printed, and although it doesn’t quite fit due to me missing a pair of slight notches on the rb67’s mating surface that force the correct orientation, it does bolt onto the RH50 perfectly. I’ll see if I can get the revised prototype printed and hopefully I’ll have an adapter that works perfectly! Still need to get the light foam and screws for it, but hopefully those aren’t too terrible to find.
