"Nature does nothing uselessly." Aristotle
Drew, I would set your camera to manual focus. Each time a bee flies in front of the lens it tries to autofocus on it, but can't because its too fast. But if you set the focus and let some parts of the frame fall out of focus you will end up with a more watchable clip. Having the focus hunting and the lens "breathing" like that is really hard to watch. Give it a try if you can. I think you'll like the look better.
