Not absolutely sure that will work, but I passed on buying a lens that acted that way. After rotating the lens to infinity and then switching the camera to autofocus, the lens would rotate away from infinity a tiny bit and emit an audible click. After that, autofocus would work. I do have an F series zoom that does the same thing, but I don't have to perform that procedure with it before using autofocus. Just a guess.
