Sony fe 100 400mm f 4 5 5 6 gm oss vs sigma 100 400mm f 5 6 3?

I don't cover Sigma lenses on this site, so I can't tell you how the Sigma 100-400mm f/5-6.3 compares. I'd rather not guess at its specs or price.

On the Sony side, the Sony FE 100-400mm f/4.5-5.6 GM OSS is stabilised, autofocusing, and fits a wide range of Sony E bodies, both full frame and APS-C. If you want a lighter, cheaper 400mm zoom, the Sony FE 100-400mm f/5.6-8 OSS weighs about 650 g. For sport and wildlife in low light, the Sony FE 100-400mm f/4.5 GM OSS holds a constant f/4.5.

If you're just starting out, I'd look at the wildlife and sport picks before deciding.
