Not due to budget restraints, but rather lack of items on the BS forum, I've been wondering if a 1.4x II will work just as well with my 500/4.5

Is it worth the wait for a III post to pop up?

Can you live without the AF? You might want to consider a 3rd party TC that does not report the effective aperture.

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.
