Which adapter are you using? LA-EA3?

I wouldn't recommend adapting Sigma A-mount lenses. Mine focus more reliably on the LA-EA4. I have no experience with the lenses you mention. Trading the A-mount version for an EF-mount version might be better.

Yes, I am using an LA-EA3 adapter.

The first link on Google for "LA-EA3 50-500" is a post here reporting, "AF works poorly or not at all"

I also find many reports that it works fine on the LA-EA4. And I find reports that the EF version works fine on the MC-11 or Metabones.

Thank you for the response. The video I found on-line (in German) shows the 50-500 Sigma actually auto focusing. I am still playing around with the settings, sure would love to be able to use this lens with my a7iii. If worst comes to worst, I will have to manually focus.
