I'm not sure if 5D II has poorer liveview than L1 but based on the DOF
calculator:
http://www.dofmaster.com/dofjs.html
If I set CoC to 0.006mm (35mm/5616pixel), object distance 5.5 meter, the DoF
is 4.74m to 6.56m. It indicates one cannot differentiate the focus between 5
and 6 meter, or I have missed something?
