P.S. There is a company that puts out an LCD ringlight. Since it goes on and off like a flashlight, you don't need to worry about P-TTL. Just turn it on and your meter does the work. B&h may list it. Or do a Google search. The limitation is that the light is pretty weak, so you really need to be close in to use it.
