I have the 100-400, purchased around ten years ago and it is sharper at 400mm than the 400 F5.6. You can compare these two lenses at http://www.the-digital-picture.com/Reviews/ISO-12233-Sample-Crops.aspx The 100-400 is clearly the winner here. I have a 5DiIII and I used it last weekend with a 1.4X. It was pretty sharp and auto focused albeit a bit slowly. I have heard that some older copies of the 100-400 were not as sharp at 400, but I have no personal knowledge about that.

i don't know what you were looking at but i just compared them at that link @400mm and the 400mm prime is clearly better than 100-400mm it has been proven numerous times that the prime is sharper at 400mm and it is an accepted conclusion by the majority of owners of both lenses

cheerz.
