Probably most of you here swear by Canon's 70-200L IS II, and for excellent reasons. From numerous forum posts here I can understand this is one of the best zooms produced, period. But I am not looking for any more info about Canon's offering. What I am looking for is personal experience of those of you who might be using the Sigma 70-200 OS. It would be great if any of you actually used both the Canon and the Sigma. Would you please care to share your opinions and experiences? I am not a professional photographer, so justifying buying the Canon is almost impossible for me. The similar offering from Tamron does not yet have OS/VC/IS. So it would be a great help to learn from your opinions and experiences about the Sigma lens. Thank you all in advance.
Haha, I was just about to create this thread of my own but saw yours. I am in the same boat as you. I am also looking at the Sigma 70-200 OS because Canon's offering is a bit too expensive for me right now. However, I am mainly concerned about these areas
1) Image Quality
2) Build Quality
3) AF sync with Canon's body. Is there any noticeable difference when trying to get a lock on your subject using the Sigma compared to Canon's version.
