Maybe check your back focus? The 1.8G, 1.4G, and hell even the 1.8D at mid-app will produce quite sharp images.

I was referring to results obtained stopped down to f/6.3 to f/8.

Generally I think the focus sensors on the D800 are too big. They therefore may cover too much subject matter at varying distances (e.g. eye versus nose wide open). This is very visible in the DX mode.

The Olympus E-5 has the option to switch to a smaller AF sensor size which e.g. is helpful to aquire precise focusing on small birds between branches.
