It's OFF. Changing it to ON does not change anything.
I see. Indeed, with Shutter AF OFF the Focus Priority does not work. With Shutter AF ON (the default) the Focus Priority works correctly (picture is not taken with no focus).
It's not documented but I suppose it's the intended behavior?
That's a bummer, I thought I could use it for "focus trap".
Added: do you think it would be a problem if Focus Priority simply didn't take pictures if there's not focus, does not matter what are the other settings?
