Is it possible to auto focus and get everything tack sharp when taking landscapes?

Alright, I'm struggling to wrap my head around the hyper focus distance thing. I have a canon 80d and just picked up the tokina 11-20 2.8. Since that camera has like 45 focus points would it be safe to stay in auto and just chimp or should I really be taking landscapes in manual focus? via /r/photography http://ift.tt/2vVrlZt
