^ I know how you feel, lenses are usually something you do not lose value in. This is just such a HUGE shift for Sigma and now with the release of a new 30 1.4 !!! Exciting times at Sigma.
I shot it at a Bat-Mitzvah over the weekend and I was very happy with the performance of the lens. I have not done all of the insane testing like everyone else has in their thread *LOL*.
I have shot more images of text than I have with any other lens !!!
