Q: 10. How I can program the program button? I can't find such an option on GFX100s body and there is no explanation from Metabones.

A: Upon reaching out to Metabones, we received these instructions from them: "Under the current firmware, the WO button(side button) of adapter of the EF-GFX or EF-X adapters can use for 1.) a shortcut key to switching between the A (Aperture Priority) and P (Program) OR switching between the S (Shutter Priority) and M (Manual) exposure modes; 2.) the quick access button to the camera menu(MOUNT ADAPTOR SETTING) for setting up the manual lens (register the non-electronic lens, etc). You can try to press the button after attached the adapter on the camera but without the lens or attach a manual lens, once you press it the menu will pop up."
