Even the expensive lens perform sharpest when stopped down. The optics are tested during production and the best ones make it into the best lenses, and average ones make it into the lower lenses. They tested for sharpness and when its within the spec it can go into a fast expensive lens (fast being larger aperture/lower f stop value. No two lenses benchmark identical. Plus no two bodies benchmark identical.

Could also be your body is back or front focusing with THAT lens on YOUR body. Which version of the lens are you using? all those purple stars from your overprocessed image tell me its possibly an older one or you have a UV filter on the lens when you took the shot as the purple is a chromatic effect either from lower grade glass. If it was a VR version of the lens did you remember to turn it off???

Have you checked astrobin for other photos taken with the D700? I would say at this point the camera is not at fault. User error / current knowledge is more likely. You should not have in camera sharpness or colour processing going on either.
