I hope you don't think I'm trying to boost my "for sale" post here, but the Tokina 12-24 F4 is a stunning lens to use on your camera.
I originally bought the lens for my own D80 a couple of years ago because of the superb reviews.
Stick a circ Pol on and behold the fantastic colours this lens is capable of on a sunny day.
If there was an FX 12-24 available, I'd have one for my D3.
