Focus issues prevalent with outer points on 5DIII!!!!!!!!!!

I have the same issue with my D600 and 50 1.4D. Central focus point is in focus, but two outer points on the right and three outer points on the left are out of focus. But my 50 1.8d focuses just fine - all focus points. I will be only using central point when /if I decide to use that 50 1.4 again.
