CORRECTED - The original A7R didn\'t have any phase detection (PDAF) hardware - it\'s not possible to add it later.
The A7 has PDAF, but it seems extremely unlikely to me that Sony would expend any effort to extend the capability of that old* camera. And for the Sigma adapter to utilize such capabilities the camera would likely need the firmware which enabled PDAF on the Sony adapter, which was released for the A7ii and A7Rii.
*\'old\' being a highly flexible term in these days of quarterly product revisions.
