The 500/4.5 + a Canon TC will only AF in the center and with certain bodies (1D series, 5D III, 7D II, etc.). A non reporting TC will AF on all points.
FWIW, I find the 1.4X III better than the II on the 500/4 IS, especially in having less CA. I'm not sure how much difference it makes on the f/4.5 lens.
