Thank you very much all for your responses. I'll consider these information before getting the new lens. Got interested with the Sigma 18-35 1.8. Will add this in my options Regards Adrian

Hi to all, Anyone here have tried/used any or both of these lenses "Sigma 17-50 2.8" vs "Sigma 17-70 C" attached on a 7D? How do they perform? focusing issues? build quality? and my main concern is the image sharpness. I will be buying a new lens for my Canon 7D. Basically upgrade my kit lens to a better optic. Right now, I would want to get information regarding both lenses I.Q. From there on I'll decide which one I'll purchase. Truly appreciate your help Thanks in advance Adrian
