This lensplate allows you to mount lenses fitted with a Canon Eos bayonet, in combination with the WRS series camera.
This combination will work with those digital backs that have a built-in ES-shutter (sensor activated electronic shutter), which work as shutterless digital back, such as the PhaseOne IQ3-100 and the IQ-4 series.
The WRE-CA can also be used to set the aperture of those lenses that have only motorised aperture. The internal battery is rechargeable. The used focal length and the current aperture are displayed on a OLED screen on the lensplate.
The practical use of lenses may be limited to those that have enough image circle coverage for the digital backbeing used.
