1.1 Sony E Mount

We can replace this board with our own adapter board to connect to the cameras I/O's

1.2 Open standard Mount

P+S Technik offers with their IMS mount an open standard. For AXIOM Beta the adapters are too expensive, but for sure an option for AXIOM Gamma.

Is there a affordable really open standard mount out there?
