im currently looking to buy sigma10-20 / tokina 12-24..i have gone tru alot of research but still very headache in choosing the right 1 for myself! sigma has HSM and wider compared to other but i afraid the finishes will peel off 1 day!but wat i knw is when shooting 10mm with sigma, the volume of light will deducted at f4 so the dark edges (marginal lumination)will look very obvious, but f8 will looks fine! what about tokina? about distortion? aberration? flare? astigmatism?
and i think i'll get it from "onestop"!
THANK YOU....
