Hey guys!

Been wanting to get a 70-200mm for awhile and did have my eye on the canon 2.8, but the sigma is just so much cheaper, and i've looked at online comparisons, and thought i'd get some owner/ user opinions.

Would there be anything drastically important that would make you choose the canon over the sigma? I am sure it's cheaper for a reason, though i can't see what it is.

Any help would be appreciated

Thanks, Imogen
