Re: 800mm f/5.6 + 1D-X + 1.4x Extender = Apparently It Can AF!
It is a little off topic but I just tested (few hrs ago) my Ef500/4IS MKI with 1.4TcIII+1.4 TC Kenko with 5D3 to get an effective 1000mm. Surprisingly good AF maybe as good as if not better than that of 500 +2xIII with 1D4 combo.
A few pictures: 1600 ISO, 1/640-500sec, wide open, supported by mono-pod.
FF: cloudy condition.
Crops:
This one is at 2500 ISO, 1/500sec
Looks like a viable option to me if the light is good.
