I have noticed quite a few threads (and not just here) about 6D focus errors with fast primes.
Having been through the agony of mis-focus and weeks of AF fine tuning with my 85 1.2 and my 24-105, I can say, it was the body all along.
I swapped my 6D within the 28 day return period for a new body and now both lenses hit focus every time with no adjustment.
Just my experience but I'd like to hear from others if they have the same issues.
