One single source told me he heard something unexpected. That Sony would release a new LA-EA (A to E-mount) adapter. UPDATE: I have been told more about this adapter:
This adapter doesn’t have mirror (same like LA-EA3) so it works with sensor AF from E-mount body.
However, it also have motor integrated like LA-EA4.
They call it “LA-EA5” and sounds like its natural naming ;-)
The biggest surprise is that this would be the first A-mount related product announcement since 2015 :)
