Mamiya Press Universal-Register/Lens distances
Need to know which lens-50 or 75mm is nearest to the film-plane.
1. mamiya register-mount to film-plane
2. distance rear-lens to film-plane or to mount. 50 and 75mm
Pls put the lens on flat surface and measure distance to the mount-position.
Must learn this to know if a lens can be mounted which must be positioned at 24mm(rear lens) from the film-plane to be sharp at infinity.
Thank you very much
