Metabones Smart Adapters and a7s issue

Recommended Posts

The Metabones Smart adapters v3 and v4 lock up the a7s on startup, typically after a lens change. Perhaps related to some kind of internal memory on the adapter. The workaround seems to be unlocking and twisting the adapter, powering up the a7s, waiting for the display to become active, then twisting to lock the adapter to the camera.

Others have reported this issue and sending back to Hong Kong at $35 each time for a firmware update hasn't solved the issue. So far it's happened with our 24-105 and 16-35 Canon L lenses (not a third party lens issue).

I haven't seen this issue with the gen I SpeedBooster yet.
