Well, digital sensors do it differently from film. The Sigma in the test was definitely flawed (uncentered) (in fact, the author mailed me that three other samples he tried out were uncentered in the same way, bottom was soft, so probably it was quite a bad batch of them!). I have had good results with the Sigma on digital when I tried out a friend's. Best regards, Frantisek Vlcek
