Well, there is a piece of information missing for this judgement:
The MTF-chart does not tell for which aperture it applies. (At least
I dont see that anywhere).
But on the other side ... this is a crop-2.7-system ... I guess it
is diffraction-limited for every aperture beyond f/5.6 ... so,
very likely the MTFs are for wide open aperture.

In the past, Nikon have always shown MTFs at full aperture
