Hi Thomas - I know you made your purchase, but thought I would put in my two cents:
I have a Tokina 11-16 DX II mounted on a d5300 which I use for both terrestrial and underwater photogrammetry. I have been fairly pleased. The distortion is no problem for photoscan - I get excellent, highly accurate results. A very high degree of overlap is key. The zoom is a mixed bag. I know there is less chance of accidently zooming if you set it at 11 or 16, but usually pull back to 13-14 mm and hope I don't bump it - that range works best based on my EQ setup, distance from the ground, and coverage pattern. My main complaint is that I wish the lens was sharper. I am tempted to replace it with a 11-20 (or a prime) - so congrats on your purchase!
