I am trying to add UWA to my collection of lenses. I am torn between Tokina 12-24 and Sigma 10-20. I love all the samples from Tokina and the fact that Tokina is cheaper, but I kinda want the extra 2mm Sigma gives. Actually 2mm X 1.6 which is even more. I am curious for those that were deciding similarly to me between these 2 lenses what did they ultimately picked and why.
