Hello:
2 weeks ago, I was discussing a comparison of the Tokina 17, vs the Tamron 17-35.
Took delivery of the Tokina and compared against our studio's 16-35L lens @ 17mm.
I found the Tokina to be contrastier, and I think because of it's apparent higher contrast, the image overall, seemed sharper than the Canon zoom. Because of the 16-35's lower contrast, it did handle deep tonal transitions, (from dark grey to black) better. The Tokina looked noisier at these deep tonal levels. Sharpening both images exaggerated this effect with the Tokina.
I've got more to experiment with, and I'm sure that I can adjust my raw processing settings to compensate for this issue. I will say that both lenses at 17mm, require ample application of the Chromatic Abberation slider for both R/C and B/Y in the CS File Browser. Without it, both lenses really exhibit strong pixel offset near the edges of the frame when viewing the file at 100-400%.
I feel that if you don't need a zoom, the Tokina is a great value! Great build quality, and a real depth-of-field scale on the lens barrel.
