You nailed it Jim.
If 800mm is not long enough and you can't get closer to your subject to fill the full frame, keep your Mark IV.
After all, the most valuable 1D X improvement over the 1D Mark IV is the new 61-point AF system. Adding third party extenders and shooting at f/8 would greatly reduce any AF advantage.


Exactly. If we let ourselves become obsessed with that "reach" at the expense of some key qualities this latest technology offers, then might as well use this sorta thing....plenty of "reach" there :
