i've got a Sigma 70-200mm f/2.8 EX DG HSM II Macro Zoom Lens and i'm in love with it, i like the 2.8 just because i can shoot indoor also and this lens didn't break my wallet. Don't get me wrong, the canon is PHENOMENAL, but if your wallet can't keep up with it... you can't go wrong with the sigma. i snagged my sigma for 650(more than my budget, but it was a good choice in the end)
with time in life, i'll own a canon 70-200 for sure. but for now, my broke *** college wallet said this will do also! lol.
i can get some sample pics if you would like
