ya im about to either buy the sigma 10-20 or the 12-24. or if i decide to not mod my car and grow the balls then ill get the nikkor 17-55 2.8 DX...i just cant decide though.
I know you hate him :tongue: But Ken did a really great comparison test of the Nikon 12-24mm f/4, Tokina 12-24mm f/4, Sigma 10-20mm f/4-5.6 and Tamron 11-18mm f/4.5-5.6. From which I based most of my purchase decision of the Tokina on. If you haven't read it and are interested you can find it here...
