Hi guys, I've been slowly hunting down what lense i want to get, and i've finally found 4 that i like, of which, any one of them i'm happy to buy. Now i'm hoping someone out there might tell me any problems they've had with any of them. They are: Tokina Zoom 10-17mm f/3.5-4.5 AT-X 107 DX Autofocus Lens Tamron Zoom 11-18mm f/4.5-5.6 Di-II LD Aspherical (IF) Lens Tokina Zoom AF 12-24mm f/4 AT-X 124AF Pro DX Autofocus Lens Sigma Zoom 10-20mm f/4-5.6 EX DC HSM Autofocus Lens Also, if anyone has any pics they're taken with any of these lenses - could you please post them here so i can see how it looks (on the widest angle if possible). Thanks in advance. Roger.
