The CA-XCD enables the use of EF lenses with Hasselblad X1D and X2D cameras. Notably Canon's Tilt/Shift lenses can be of interest, since these have image circles large enough to cover the Hasselblad's 33x44mm sensor. There's no electronical connection between camera body and lens. The aperture is set at the adapter.

The Hasselblad camera has no shutter inside the body. Therefore one has to rely on the camera's on-sensor shutter. The rolling shutter effect implies its limitations.
