Sony a7RIII: With Canon, Tameron, Sigma Glass and Metabones Mark IV/Sigma MC-11

It looks like Sony might have put some extra effort into making AF work with adapted lenses on the Sony a7RIII from the various Metabones Mark IV/Sigma MC-11 videos on the web. My Techart adapter still works great, but when using eye AF with it I get a lot of out of focus photos, yet the feature appears to work. Metabones Mark/Sigma adapters appear to be working well though.
