Is the sigma 70 200mm f 2 8 dg os hsm sports good for sports?

Yes, for most sport. It's a constant f/2.8, so it lets in plenty of light for fast indoor and evening games, and it's stabilised and autofocusing. On full frame, 70-200mm is right in the range I'd pick for sport from the sideline, as covered in wildlife and sport. On APS-C it reaches further, so it works well on a crop body like the Nikon D500.

If you shoot distant action, like a big stadium or a field from the far stands, the Sigma 120-300mm f/2.8 DG OS HSM Sports gives you more reach. It's bigger and heavier, though, so think about how long you'll be carrying it.
