“This product is the 2nd generation adapter for mounting Canon FD mount lens on FUJIFILM X cameras. It is equipped with 4 groups of 4 focal reducer lenses that reduces the focal length to 0.726 times in the adapter, even with cameras adopting the APS-C size image pickup device, it is possible to shoot with the original full frame angle of view of the lens.”
