I typically shoot wildlife frequently and I have Canon 600d with Canon 100-400mm isII. Is EF Extender required at all, since I use the lens on cropped frame. If yes, then which one is preferred - Canon -Extender EF 1.4x III Teleconverter or EF 2X?

Although no Canon TC will AF with that combo, there may be a third party TC that might AF to some extent (perhaps a Kenko?). You might have to google for info.

For instance my Tamron (non-reporting) 1.4x TC will AF well enough for BIFs with my 400/5.6 on my 70D (even though it's not specced to). With other bodies AF was sketchy or even impossible (AF varies by Body, Lens, and TC).

Some samples here...

Good luck!
