Yes, the old 100-400 (ver 1) was almost a 20 year old design, it doesn't compare to modern lenses from Sigma, Tamron, or Canon.

 

However, you won't find a better and more versitile lens than the EF 100-400 L IS II.  Even with a 1.4X TC III its image quality is on par with the best Sigma and Tamron have to offer, and without a TC its image quality is unmatched, except by the EF 70-200 f/2.8L IS II. Add to that a short minimum focus distance and the EF 100-400 L IS II is the best lens in the 100-560mm range.

Note, however, that the 70-200 (any versions) is a constant-aperture lens, while the 100-400 isn't. Outdoors on a bright day that may not matter, but it's a reminder that the 100-400 isn't a universal substitute for the 70-200 (especially not for the f/2.8).

How well does the 100-400 Ver 2 + a 1.4 TC do at focusing on fast objects (over 100 MPH) travelling towards or away from you but at an angle something like the plane in this photo? It would be on either a 1D4 or 7D2.

1D Mark IV and EF 100-400mm f/4.5-5.6L IS II USM.  All you need is Photoshop.  Too bad DPP cannot stack photos.

I agree, my intent wasn't to say that the EF 100-400 L IS II could replace the EF 70-200 f/2.8L IS II. But, that the EF 100-400 L IS II actually matches the image quality of the acclaimed EF 70-200 f/2.8L IS II.

The Great Egret I posted above was coming directly towards the camera in flight. I suspect the closure rate on the camera would be similar to the plane approaching at a 45 degree angle. I haven't used the combination at the race track as it is just too long for where I normally shoot from. The only time I notice focus speed at all with the 1.4X TC III is when the lens is set to 'Full' focus instead of '3m to infinity'. Then focus speed is noticeably slower. I suspect any complaints about focus speed of the lens stem from that.

My phone rang when I posted this shot.  I didn't finish my remarks.  I used LR on this shot, and PS when I want to make "repairs".

I used no extender.  Image quality comes from lenses, while focusing comes from the camera bodies.  I have a better success focusing with the 1D4 than the 7D2.  Both have sophisticated AF tracking.
