Perhaps if the crews shot a short amount of test footage and then watched that back, this sort of thing could be avoided or minimised? Camera adjustment errors should show up on the raw footage, I appreciate it isn't processed and corrected but if it's an obvious focus issue, for example, it should show up?
Imagine spending all day shooting a scene to discover that your camera settings were broken somehow and the footage is terrible. It's a waste of everyone's time if that could be avoided somehow by more careful testing and setup.
