    For instance, a relay lens system must be added if the adapter is to be directly mounted to a camera's body (bypassing the standard lens, as if on a Canon XL1 or XL2 and the Sony EX3). Also, a prism system that is used on some adapters that correctly reorients the image rightside-up adds to the cost.
