D800 (and D4)' astonishing AF module.

When I was trying out the D4 and D800 during the D4/D800 demo day early february at Art & craft in Ghent, the camera characteristic that took my attention the most was the extreme good AF module.
About AF precision, AF speed and AF with a lens TC/combo or lens/extention tube combo D800(and D4) even work significantly better than their repectiverly predecessors D700 and D3s.
During the D4 and D800 demo days at Art & Craft back in February I tested D4 AF precision with an extreme application:
I mounted my 3 kenko extension rings between the D4 and my 105AF-S and of course with a very limited DOF but handhold the D4 was autofocusing without problems.
The setup of that I describe here above:
And a result in a picture:
Take care: F14 handhold and iso 12800!!!
