^My lens is 18-55mm though, how does 300 apply? It seems when I go around 20 it blurs, but even up to 40 sometimes. Other times 40 makes it still, depending on the lighting conditions and zoom. I think the only thing I really get is a higher number (not to high) will still it, and low number (not to low) will blur motion. So in essence I think I partially get shutter speed but yeah.
