First off, the Canon extender will not work on the camera lens combo. I mean, yes, it will work, but will not autofocus. I had this combo and tried taping the pins so that the autofocus would work. That didn't work either. (Google taping pins on Canon lens)
You have to live with what you have or upgrade the lens is you need more focal length. If you had the new 7D MkII and the new 100-400 MkII and the 1.4x Mk III, then it would work but autofocus would be slow.
As I pointed out earlier, Subject line should have said Canon 7D Mk II. I was really trying to find out if the Canon 1.4X III extender would give better results than the Keno 1.4 extender I have if used with the older 100-400 L lens.
