Lens mount adapters for M645 lenses from Fotodiox are designed for the older lenses from the Mamiya era of cameras. Newer lenses that are designed for Phase One cameras, while they use the same mount, will not work with our adapters.

 

With the introduction of the Phase One 645XF camera, Phase One also introduced an extended set of signal pins for communication with the lenses (this is there in order to offer new functionality in the future). On the Mamiya 645 lens there is a bayonet ring which goes inward in the bayonet fitting which is not the case on any of the more modern AF range.

 

Between the missing bayonet fitting and the extra set of pins, those lenses will not physically mount onto our adapters.
