Canon is not supposed to be able to autofocus at apertures slower than f5.6 although I have read about a few cheats. At f8 you may be just out of luck.

The 80D has 27 AF points that officially work at f/8. The center group in red will still use cross-type sensors, whereas the others fall back to line sensors at f/8 with the extender.
