Question about Sigma 24-70mm F3.5-5.6 AF Zoom Lens
I just got this lens for Christmas 07 with less than 100 pictures on it and now the autofocus doesn't work. When I depress the button it slightly moves around infinity symbol but that is it. Sometimes I can depress the button all the way and it wont take the shot. I can manually focus and when I move the focus ring from manual to auto ever so slightly I feel & hear a click. Then sometimes it will focus but inevitably ends back over at infinity. I have it on a Canon 20D and my Canon 70-200 2.8 has no trouble when I attach it, regarding focus. I bought this lens because the price was better, I;m beginning to wonder if I get what I paid for. Any thoughts.
