OKAY ! .. He is what I am trying to do. ??? I have a couple of Canon FD teleconverters and I want to use them with my Canon EOS lenses. I have the adapter ring that mounts the Canon FD lens to my Canon EOS XS. BUT ! I want to mount the an EOS Lens in front of the Canon FD teleconverter. So I need a female Canon FD to Female EOS Coupler ... Is there such a thing ?
