Picture request for sigma 24-70mm on a dSLR preferably 350d

Well I believe that the Canon weighs around 950g, and the Sigma 700g, so there should be a noticeable difference between them.

That point could be argued all day long.... I had the Canon lens and it was a very tough build.... very solid, very strong. I think that is why it is heavier.... possibly more glass as well.

That said, here is the shootout link.... judge for yourself:
