That said, the 100-400 + 2xII is pushing the edges of acceptable. Put in on a tripod, stop down a couple of stops, and you'll get images that are usable. But wide open you'll find things pretty soft.
And therein lies the problem.
Even at ISO 800 on a sunny day, I'm shooting wide open at f11, at a mere 1/125th of a second. And that's just not fast enough for me, even with IS.
I have got a few usable images using the 100-400 + 2xII. But nothing I couldn't have got using a 1.4x and cropping a bit.
Here is a crop from a picture shot on 100ISO film in an EOS3 with the 100-400 with 1.4x at 1/8 sec handheld wide open of a Vermilion Flycatcher 4 years ago or so. This is the best shot of 3 that I managed before it took off. It's not perfectly sharp, but not far off what I can get with a two tripod setup with a 509 and 320 Gitzo.
This combination I still find useable, but the 2x disappoints.
Sorry, forgot the link:
