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)?

Check this out on Metabones website: (The adapter I received has no manual!)
