Best lens for a D800E and landscape panorama shots

I am looking to maximise my D800E and I like to do landscape panoramas/mosaics.

50mm F1.8g is very sharp as is 85mm F1.8g. I also use 24-70 at 24mm most often and it works really well.

But for absolutely max quality what have you found would be best?

Perhaps the new 70-200mm at 70mm and F7.1? Or Zeiss 100mm F2 planar?

Nikkor 60mm F2.8 micro? Perhaps the new Sigma 35mm F1.4?
