Hi all:

Thinking about this combo:

20D, EF 100-400 and EF 1.4XII teleconverter.

You will lose AF with any 10 pin TC. I use a Kenco non-Pro 1.4x TC (7-pin)
which allows AF. Quality is not bad at all. It is half the price of Canon.

AF will be retained with the Kenk Pro TCs too. But with an effective f8 @ 400mm, expect slow autofocussing and hunting in any
conditions other than bright light.

Cheers
