XPimage Modify Adapter 0.71x Focal Reducer for Mamiya 645 M645 Lens to ARRI ALEXA MINI PL Mount Cinema Camera

This XPImage's modify kit for the Mamiya 645 lenses is specially designed to convert the M645 lens to the Arri PL camera, allowing Mamiya 645 mount lenses to be mounted onto PL camera bodies. The 0.71x optic adapter gets rid of crop factor, and increases the aperture. 

This solutions is to instead the XPImage M645-PL 0.71x adapter.  which have limitation in PL cine bodies. (the previous adapter can't install to all of the PL cinemas. but only a few could be use. So XPImage publish this modify solution and make it work for most of the PL mount cinemas. the 0.71x function could be work too.)
