Yes, in fact they will react with an F16 lens as well. That does not mean they are designed or capable of producing even adequate performance at that light convergence.
...I\'m not sure I\'m understanding your point here. I\'ve made plenty of fine images using what you claim is inadequate/incapable, and there are countless others who have done the same. Slightly slower, less responsive AF is still better than none at all.
1D III + 100-400L + 1.4x actually has decent AF speed in normal light at least. I would be shooting barn swallows with it, but I\'ve used it for dragons in flight, larger birds and normal wildlife activities.
Well if they could make a 100-400 f/4 that was under 2kg and $2K, maybe I wouldn\'t care so much about losing AF @ f/8.
