Yeah, the "real" ones, like Canon TC14 and TC20.
Well, some of the aftermarket teleconverters *might* work, but I doubt that they would work that well at all. And probably on EFs lenses, due to the added rear element sticking out of the lens barrel, not at all. The optical quality would be equivalent to a Coke bottle. BUT, that would not stop some of the schlock house selling the OP one - and then making him wait for a refund that may or may not ever be made.
