Thanks for the kind words. I agree it's not ideal. It's a trade off. With a large aperture, you are reducing the likelihood of motion blur but increasing the likelihood of being out of focus. Blurry either way.

Try it both ways and see if you prefer the look of motion blur to the look of being out of focus. Motion blur sometimes looks more natural and can convey motion, so BigV has a good point.
