I know that.
I am not sure if the BMCC has such a hole.. I don't have it with me right now so I can verify that. I know my other camcorder does.
The issue was that it became unscrewed just a little bit making it protrude just slightly from the bottom of the plate. It wasn't even that much. However, it was enough to cause my camera from completely locking in. The battery has a tab the moves up after the plate is slid in and although this tab slid up.. it didn't slide up all the way since the screw was protruding on the bottom of the plate. When your out running and gunning it's easy not to notice if the tab doesn't go all the way up which is a problem because it means your camera is not locked in.
That is what happened and my camera almost took a 6 foot nose dive. I managed to grab it in the air but it did freak me out. Just wanted to put this post out there so people are mindful that this can happen so that they know to pay attention to it.
