With 400mm f5.6 lenses + taped 1.4X TeleConverter (Tamron SP), the camera's center AF point is useless (hunt endlessly), but the peripheral focusing points are still useable.
My old 400D can handle this situation much better.

Focusing Test with Yellow-vented Bulbul
Testing my new camera with this very common backyard bird - Yellow-vented Bulbul (Pycnonotus goiavier).
With 400mm f5.6 lenses + taped 1.4X TeleConverter (Tamron SP), the camera's center AF point is useless (hunt endlessly), but the peripheral focusing points are still useable.
