p.1 #1 · 7D will focus at F8 with the Tamron-F 1.4X TC
This TC will autofocus using the 100-400 L on a 7D.
Note: This was at the 400mm setting on the zoom.
I was at the Rio Grande Nature center on saturday. A friend with a 7D used the Tamron-F TC on his 7D with the 100-400L. The autofocus was usable and his images look sharp on the dispaly.

Yeah any non reporting or a reporting TC with the extra pins taped will work.
I use my 7D with a100-400 and TC sometimes.
However the are issues. I find the middle point does not want to know at all , so if I use zone AF in the centre zone I have to be aware of the missing middle one.

I've used the Kenko taped somewhat successfully with my 40D and 100-400L
As said previously, it can become hunty, and depends what you are trying to do.
