Also if you could manage to put (impossible) ARRI/Zeiss Master Prime 50 mm on a full frame 35 mm photo camera you'll get natural and optical vignetting because MP lens is designed just for S35 mm but not designed for 35mm photo full frame.

That is correct, you may get almost a circular image but the focal length does not change.
