Hello all,
I have been using the 7D II + 400mm f/5.6L prime + TC 1.4x III and many have been asking me about the results, so I have made a small compilation on Flickr (see link below).

Generally, I would say that at f/8 (wide open) the sharpness is acceptable, but you might want to stop down to f/11, which is not a problem under good light and a stable tripod. Besides, ISO 800 for the 7D Mark II is not a problem at all.
The focusing speed decreases a lot, but it remains very accurate. Notice that I use back button autofocus with AI-SERVO.
Let me know if you have any questions.
Best regards,
Fabio.
