I have been eyeing off this one as well. David Kingham uses it quite a lot in his great nightscape work. From memory of the hangout that I did with him, this shot
http://www.davidkinghamphotography.c...383c#h5600383c is something like a 27 image panorama using it. If it is anywhere as good as the Samyang 14mm F/2.8 with virtually no coma, then it will surely grace my camera bag very soon.
