Sigma 300 600mm f 4 dg os sports vs sony fe 200 600mm f 5 6 6 3 g oss?

These two overlap a lot, so the choice comes down to light, reach, and budget. The Sigma 300-600mm f/4 DG OS Sports holds f/4 across the whole zoom, so it gathers more light than the Sony. It also fits Leica SL and Panasonic S bodies as well as Sony E.

The Sony FE 200-600mm f/5.6-6.3 G OSS starts at 200mm and gets darker as you zoom in. It is the usual bird lens on Sony, and I think it is fair value.

I'd pick the Sigma for serious sport and low-light work, and the Sony if you want a more affordable start with birds and wildlife. Both are stabilised and autofocus. For more on reach, see wildlife and sport.
