Is anyone using this combination? Do you like it? In addition to the autofocus issues (needs to have f/8 to autofocus), I am finding the shots straight out of the 5DIII to be close to or better than those taken with the 1.4 TC. I am wondering if the 1.4 TC doesn't degrade the IQ much of better glass (70-200 IS II, big whites, etc), but does in the 100-400 L.
A few examples of approximately 100% crops (yes, I am pixel peeping). All shots taken from tripod, remote release, manual focused using live view. Took multiple shots and below represents the "best":
