wow, I thought it buzzed more than that!

Have you used the lens in the video for sports or fast action?

[scavo2003]

Hmm, I'm just not sure whether to spend more money on HSM. If it results in more keepers while tracking, I would definitely buy one. If it doesn't result in significantly better results, then it's not worth it. But I can't find one used anyhow.

For tracking sports does not having HSM make a difference?

@scavo2003 I have not used HSM verson yet, but based on my experience HSM verson will be more accurate and smoother.
