Does A7iii's new firmware 3.10 reduces autofocus functionality of third-party lenses?

I read that the new firmware update version 3.10 deliberately make third-party lenses worse, especially the Tamron 28-75 f2.8. Is this true?

Hi there,

Welcome to the Sony Community.

I'd recommend getting in touch with the Support team here to discuss this further.

Best wishes,

Sean
