What is the weird sound that comes from my Lumia 1020 while focusing?

[Windows Central Question]

I have installed Windows 10 insider preview on my Lumia 1020.
Everything is fine except with the camera. While I try to focus an object
the camera makes a "teeeeeeeeet" sound. Even while I'm filming on focus, the
"teeeeeet" sound will be captured by the microphone. Can someone give me an idea
what to do?
