Lenses / Please help, did I receive a defective lens? 40mm f/2.8

Hi, I just got my lens from Amazon yesterday, and everything is working good except it makes this really weird noise when I focus manually on MF mode, it's even louder than the AF sound which I find strange... Is this normal?

It sounds something like this:

Manual Focus Noise from Canon 40mm F/2.8 Pancake STM lens on T4i 650D	Small | Large

Any help would be appreciated, thanks!
