Dear Alexandre, I only have experience with the Sigma EX 28-70/2.8 anc i can say also that my expectations were far exceeded by the performance of this lens. Even though, after having owned a consumer sigma 80-200, I was very dissapointed in its build quality....(it fell apart in my hands and never wanted another Sigma) I have been using it for 2-3 years now and and its fantastic value for money, and have gone on to purchase the 80-200 2.8 EX, another great lens, somply because pentax prices are way beyond my monetary capabilities
There are some links to tests here.... http://www.republika.pl/mparvi/testy_ang.htm Perhaps there are tests...oh, and the sigma has 77mm filter and weight 100g less than the Tokina... --- "Alexandre A.
