Can anyone recommend the best fisheye lens for a full frame camera?

I am using a Nikon D800E.

Sigma 15mm F2.8 is often commented on, I think they also make a 10mm not sure if its full frame or not. Nikon 16mm F2.8 seems good.

I want F2.8 for nightscapes so the Nikon 16mm F3.5 would be too slow.

Greg.
