I want to get a lens I can use for indoor high school wrestling and football. With my budget I’m between these two. Any advice is greatly appreciated!
- Tamron SP 70-200mm F/2.8 Di VC USD For Canon or
- Sigma 70-200mm F2.8 EX DG OS HSM Lens for Canon
I'd used a Sigma 70-200 f2.8 for Nikon in the past (I think around 2013). I'm not sure if it's the same model as you described, but I can say that it was quite nice. I used it to photograph a nighttime football ("soccer") game and had no issues at all.
I can tell you that when I later got the actual Nikon 70-200, its biggest boon was its autofocus speed as compared with the Sigma's. But in terms of image quality, etc. the Sigma I'd used was perfectly adequate (for portraits as well) and I'd continue to trust Sigma as a brand.
(They do make the famous 'Bigma' after all!)
