So I normally shoot outdoors, wildlife, landscape and travel type stuff. So in a studio with flash and lights is all new to me.
While taking a lighting class I ran in to an issue. I was shooting a Canon 5d mkiv with Canon 2.8 70-200 L IS 2. The camera was refusing to fire while on auto focus. Now it was dark and we were using flash. If I stepped out of the room in to a lit room the camera fired fine. When I stepped back in to the studio into the dark the camera refused to fire. Once I turned the auto focus off the camera shot fine. My theory is there is a setting that won't allow the camera to fire unless it can find focus, but I am not sure and I can't seem to located it.
Can anyone give me suggestions.
