Nate has had this problem on several of his lenses. He says that Sigma's lenses have trouble communicating with Canon bodies. He says you need to get it replaced, which you're already doing. But give the lens a chance when you get a new one - it's really good for the kind of lens it is. > What do you guys think - can I trust a Sigma EX 70-200 f.2.8 > APO HSM DG will > do a good job, or will it let me down like the 18-125? It just depends on the lens; sometimes you get a stinker, but it's never happened to me. I have a couple of EX lenses, the 15mm fisheye and the 20mm f/1.8, which I like a lot. Amita
