Samy,
Those MTF numbers are beyond what most test sites use to even measure 20+ some years ago. 3000 use to be the max, but apparently the 50mm f1.2 at f4, in the center exceeds 3600 or any other Nikkor lens according to that site.
Check out the MTF graph. You want the aperture all the way down to f/4 or less to get a flat(ter) field. It works well for portraits at the higher apertures.
