S100 video noise from AF

Thanks to all for the feedback. It could be that there are varying degrees of noise, but I imagine not much. I know that on my S100, when shooting a video in the back yard with just normal ambient sounds, I can still clearly hear the clicking and tapping as I pan around the yard. It would also be obvious when shooting any outdoor nature scene. Others may have slightly more or less noise.

All in all I'm pleased with the IQ on my S100, though, so will likely be keeping it since it appears all of them exhibit some degree of noisy AF anyway. A bird in the hand....I'll just use MF on quiet videos.
