Nightynight

I'm lucky enough to own all three lenses in question. For night photography, my pick is the Samyang 12 f/2, followed very closely by the 16mm 1.4. Long way after that would be the 10-24 due to its lesser light gathering ability. Only reason 16mm is in 2nd position and not leading the pack is because of its very poor coma performance. If you don't mind cropping the edges to about a 18mm equivalent, then the 16mm is stunning!

Bought this lens for astro photos due to its incredible wide angle to large aperture combination. On paper it should own everything else out there, and if you don't mind cropping out the edges, it basically does. You do lose a couple of mm but I'd take more light over wide angle anyway. Sadly the edges show significant coma which takes this lens down a couple of notches if you're into astro. Having said that, I've taken the best astro photos in my collection with this lens, as well as the Samyang 12mm 2.0.
