I use it on the D700. And mine suffers from heavy CAs (wide or closed), heavy vignetting at wider apertures. The sharpness is ok in the center but the FX sensor is (and I am also) very demanding for corner/edge sharpness at closed apertures.
But for a 20mm F/2.8 lens at that size, I think these are quite normal...

According to the review here, the IQ is very good already at f/5.6 on the D3X with quite moderate distortion...
