Since a standard lens adapter will only function as an extension tube when mounted to universal bellows systems, Novoflex has developed a Short Adapter for Novoflex A Lens to Fujifilm X-Mount Camera that will keep the overall system more compact while enabling the use of a bellows system on your mirrorless camera. It will not grant infinity focusing when used with standard A-mount lenses and is purely mechanical, not transferring any information to or enabling control from the camera body.
