I have the Tokina 12-24mm/4 ultra wide angle lens for my Nikon D70. I’m not sure about the color rendition though.

This picture was shot at 1600 sensitivity so you can see some noise, but it’s still better than having no picture at all. I think I like this lens a bit more than my 18-70mm Nikkor. It’s actually the first non-Nikkor I’ve purchased.

The big drawback for my shooting is that if you want to use fill flash, you have to zoom in to at least 20mm otherwise you will get a big shadow in the bottom of the picture. I guess I’ll be able to work around this, maybe by keeping any foreground detail away from the shadow, but it’s annoying if you permanently have slow/rear/-0.7ev (my fill flash settings) always in the camera. Actually this problem would be even worse with larger lenses like the 2.8 aperture lenses.
