Nikon D4 vs D800 in light of the recent dxomarksresults

One point often overlooked is the handling of the D4, it is very good indeed, with more physical controls, better vertical operation than adding a grip to the D800.

But in practice any of D4, D3S, D800, D600, D700 are very capable cameras, your willingness to spend money is a major factor in the purchasing choice  , combined with the choice of frame rate vs resolution.
