Canon M100 + adapter + EF 70-300 IS USM = noisy

Hello forum!

I have got Canon M100 (great camera in terms of IQ). I just bought MEIKE adapter MK-C-AF4 and used lens, Canon EF 70-300 IS USM. I got good images of this combo, but this lens is little noisy. I mean ultrasonic stabilization is noisy, Is it OK? Is it normal in this lens?

Second thing, I don't know how to switch off continuous AF in camera. I choose "One-shot AF" (did not find anything like AF-C). When I walk with this camera/lens running autofocus is still working, and lens is changing their length (of course I can turn MF on lens but this not optimal solution ). This brings additional noise in lens, because lens is constantly adjusting focus. How to fix it?

Thanks

Regards,
