You choose the 120-300 Siggy over the Canon glass? So, the auto-focus is not an issue with your lens shooting sports at all?
Yeah, often for football I do choose it, the versatility with the zoom, to me, is worth the trade off. I dont even carry my traditional 2nd camera with the 70-200 anymore.
Autofocus, honestly I cant tell the difference. I've used the 120-300 for volleyball and football mostly, some soccer. Soccer I tend to use the 400 just for the reach, same with baseball. Although I did shoot quite a bit of high school baseball last year with the sigma.
Color and autofocus I cant tell much difference between the Canon's and the Sigma. The only difference I can really tell is just a touch of sharpness loss, but then again its a zoom. What zoom is ever going to match the 300 or 400 primes?
Keep in mind too, I shoot with the end product in mind. 90% of the time I'm being paid by some magazine or newspaper where the final prints really arent going to be the best quality anyway and any difference in that lost sharpness isnt even noticable to me.
