5D3 works very well with bare 100-400L and AF fast.

I tried 5D3 and 100-400L with 1.4x TC III. It still AF OK under good light but its sharpness is noticeably worse and AF hung under poor light or impractical to track on fast moving subjects. It's not very practical in general to use TC with 100-400L.
