How is the sigma version? Do you Use it on a crop or full frame body? Ive considered the sigma before but after using the canon mark ii on a number of occasions ive been leery of going that path.
The biggest difference between the two is focus speed. We give the sigma 70-200 f/2.8 to our interns, so I've used it a few times before. The focus speed difference is pretty extreme. The Sigma isn't AWFUL by any means, but the Canon MkII is the best of any lens I've ever used. It pretty much has to be near dark for the 7D to search for focus on the MkII, while it's not exactly routine, but not uncommon either for it to search for focus on the Sigma.
The Canon is also a lot more consistently sharp over its entire range of focal length and apertures. While I'm sure there are certain aperture/focal lengths combos that are worse than others, I've yet to find them. Such an amazingly consistent lens. The Sigma is a touch soft around the corners at 2.8 on either extreme end of its focal range.
