I know there are threads for Sigma 120-300's, and all of them seem to discuss all 3 versions of Sigma's 120-300:
1. Sigma 120-300mm f/2.8 DG HSM
2. Sigma 120-300mm f/2.8 EX DG OS HSM
3. Sigma 120-300mm f/2.8 DG OS HSM Sports
I want to know about the Sports lens, and only the Sports lens. And one of the most frustrating things I am finding lately is, it is difficult to sift between the thousands of BIF photos to find any sports shots. Don't get me wrong, I love nature photography, but I've struggled to find many posts about sports with this lens. And when I find them, I am not sure which version they are referencing sometimes.
So, does anyone have any experience shooting sports on the Sigma 120-300 Sports lens?
Also, how do you find the tracking on AI SERVO - on a 7D, 5D3 or 1D4 or 1Dx?
And lastly, how do you find the lens with both/either a Sigma and/or Canon tele converter?
