I just got the Metabones EF-E MkIII adaptor. It works great on the A7R. But does anybody know what is and how to use that "wide open button" on the adaptor?

On the website it says it's opposite to a dof preview button. But isn't the lens is always wide open anyway? Is it for movie mode (I need to play with that to see)?

I would guess that if its the opposite of a DoF preview button the lens is stopping dowwn when you stop down the aperture in camera, giving a constant DoF preview. In low light you may want it wide open to give a cleaner live view for example.
