Just have to CNC the mount which I have created the 3d model for.
I 3D printed a prototype mount which worked fine and allowed me to tweak the flange distance to get it just right.
Anyhoo, it's a Mamiya 110/2.8. I've modified a fotoman helical to take the slightly larger Seiko shutter (not a copal #1 size).
Anyone who ever shot this lens on the RZ knows how good it is. I'm looking forward to using it with the groundglass on my SWA.
