This lensplate allows you to mount lenses from the Mamiya-645 series, in combination with the 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, such as the PhaseOne IQ3-100 and the IQ-4 series.

The aperture of the lenses can be set manually, the shutter (if applicable) needs to 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.

The use of Mamiya 645 lenses from the ProTL system allows for a manual aperture setting.

The use of the later lenses of the DF and XF system is mechanically possible, but there is no communication between the lens and the camera body. This means that electronically set apertures can NOT be controlled.
