Cambo WRS-M645


This lens-plate adapter allows you to mount lenses from the Phase One XF/DF and Mamiya 645 systems (“M-mount”), on Phase One XT and Cambo WRS series camera.
This combination will work with those digital backs that have a built-in shutter (sensor activated electronic shutter), which work as shutterless digital back, which include:
  • Any variant of the Phase One IQ3 100MP (Standard, Trichromatic, Achromatic, etc.)
  • Any variant of the Phase One IQ4 100MP (Trichromatic, etc.)
  • Any variant of the Phase One IQ4 150MP (Standard, Achromatic, etc.)
Please note that the aperture of the lenses must be set manually, and the shutter (if applicable) must stay open. The practical use of lenses may be limited to those that have enough image circle coverage for the used digital back when using shifts. Please see our blog article here for more information.
Mamiya 645 lenses from the ProTL system allow for manual aperture setting.
Later lenses for the DF and XF system are usable with a workaround, again detailed in our blog article here. There is no communication between the lens and the camera body. This means that electronically set apertures can NOT be controlled.
