I would prefer the Voigtlander 20mm f3.5 SL II over the Nikon 20mm f2.8. Very compact, but no AF of course. And actually very nice optics.

The Sigma 70-200mm f2.8 OS HSM is a good lens, but just mind the big focal breathing towards MFD, so depending on what you use it for it might not give what you want. Wide open it is not sharp from corner to corner, but depending on subject wide open that does not always matter. Something to keep in mind, though. Stopped down it improves a lot.

Maybe not what you are looking for.
