I've been bitten by the sports bug and it looks like I will have the opportunity to shoot more hockey, soccer and basketball in the future. Currently, my longest lens is the 135L and that just wasn't long enough for hockey. 300 would be perfect for me I think. Looking at my options in Canon glass, they are currently out of my range but Tamron and Sigma offerings in the same length are lower priced. I have no experience with anything other than a Sigma 50 1.4. My other two pieces of glass are Canon.
How would something like this compare to its Canon counterpart?

Also, does anyone who has experience with either options recommend shooting with a long zoom like that or do they prefer a long prime such as this?

I want something pretty much for sports and possibly wildlife but the main thing will be sports. And I like how quick the AF on the 24-70 2.8II or 135L is so thats what I am trying to find in a longer lens.
Thanks all.


(24Lii, sigma 50A, 135L), and for the other ends of the spectrum, sigmaEX 14mm2.8 and sigmaEX 100-300F4.
