comment:I bought the Tamron first because of very good reviews. However, I was somewhat disappointed. The field curvature especially at 17mm is very pronounced - the edges at 2.8 are terrible. In the meanwhile I did get a reasonable priced used Sigma. At 17mm 2.8 it is a little sharper in the center and a lot sharper on the edges. (The Tokina is better, though). At 24mm I could not tell the difference to the very good Minolta 24mm. At 35mm and 50mm it is sharper on the corners and less sharp in the center than the Tamron. CA is more pronounced. Color is a little warm/yellowish. Vignetting is similar to the Tamron. 50mm is a little shorter than the Minolta 50mm f1.4. Sharpness at f2.8 is comparable, but the Minolta pics look a little crispier. I like the HSM. OS is marginally better than SSS, but no reason to buy the lens. Build quality is better than the Tamron but not as good as the Tokina. I will keep the Sigma and sell the Tamron.
