I have a Nikon D800E and am looking at what is the best lenses for this sort of work.

I have the 14-24mm F2.8ED which is the best in its class. 30 second shots at ISO6400 seem fairly bright although star trailing is evident especially away from the pole.

I was thinking of 24mm F1.4.

Usually fast lenses suffer from chromatic aberration. I was wanting some suggestions about lenses like this.

Choices are:

Nikon 24mm F1.4 - highly regarded, $2100 expensive.
Zeiss Distagon 21mm F2.8 a bit slow, may have some chromatic aberration but bound to be a lovely sharp lens about $1700.
Samyang 24mm F1.4 about $700-800 seems to get a good review, their 35mm F1.4 got 2nd highest DXO mark for lenses - no mean feat and reviews put it in many ways better than the Zeiss 25mm.
Sigma 24mm F1.4 - I don't know much about this lens but Sigma often comes across as a medium quality lens maker.

Nikon 16mm fisheye F2.8ED. Nice wide field. About $800
Sigma 8mm fisheye - highly regarded in the widefield panorama groups. Super wide. About $800

Others?
