On A7R4 works with Sony 24-70mm and Sigma 50mm F1.4 Art (after update at Sigma Service center). I see no reason why the A5 adapter wouldn't work with other SSM lenses. Of course it does work with the Minolta and Sony screw drive lenses as per its' specs.

Was that a firmware update? If so I have a docking station that came with my Sigma 24-105 f4 ART for that purpose.

My understanding from discussion with the Sigma rep was that the update needed for my 50mm Art lens could NOT be done via the dock.

I imagine the dock is not compatible with all the lenses.

The dock is compatible with all Art, Contemporary and Sports lenses, but it was that particular upgrade that could not be loaded with the dock. Maybe there was a bigger change than just firmware, maybe a chip inside needed an upgrade too.
