D800 focus with 1.4 prime lenses is very variable and inaccurate

I don't believe the 6D has a better (more accurate, consistent) focus system though. The one i tested in the store also seemed to miss focus a couple of times. As any DSLR does sometimes. There is always a chance for quirks. Specially with technology so complex and precise. Combination of 10's of DSLR with 1000's of lensen etc... Issues are inevitable and random.

I'm sorry to hear your D800 doesnt work well with 1.4. Personally i never have issues. I dont use 1.4 much either mind you. In my professional enviroment i feel this DSLR deliver's and i can trust it.
