Then both the 15mm and 21mm Zeiss might be worth your consideration as well as the Samyang 14mm.
I am interested in the just announced 24mm PC from Samyang for architecture!
Re. the 14-24 DigLloyd has documented focus-shift, which is a lens-design issue, not sure if that was a factor in your case (on stopping down focus shifts AWAY from focal point in central area of the frame).

Depending on how he uses the 14-24, focus shift might very well be an issue for the OP. The majority of my own captures were either at f/2.8, where there is no focus shift, or at f/8 and smaller, where the DOF is large enough to mitigate any focus shift. Consequently, I never had any problem. If you use f/4 or f/5.6, you should move the focus a little forward to account for focus shift. If your camera has LiveView you can always use this approach with MF at high mag.
I'm not saying this lens is bad at all. It sure is better than the 14mm prime which is a puzzling failure. This field curvature and focus shift stuff tho is kinda troubling, trying to account for that by guess and by golly. Who has the time to test out every distance and focal length and etc etc. Anyway, thanks nikon for 36 MP flexibility to iron out some of this for final delivery.
