Hi

I think you need to upgrade the lens firmware.

I have a 60D...

I think you need to go to Canon Authorised service center to upgrade the firmware if you dont have 5D3.

Regards

Thank you anyways!

My copy (on 5D2) sounds just like this one
Canon 40mm f2.8 STM Lens (HD) Review - DSLR FILM NOOB
EDIT: I'm sorry, time code didn't work, it is at 3m 45sec.

It is completely quiet if I turn the focusing ring reeeaaally slow, faster MF makes more noise.

That video only shows the AF sound though.

And mine is silent too when I MF slowly...

So I guess the MF noise is normal? If so then I don't know if I want to keep this lens...

I have had the same lens now for a couple of months, and i have had no problem with noise when you focus with that lens, i would say it is defective... it's suppose to be a very quiet lens. just me...i would send it back.

The AF on mine is pretty silent but the MF isn't....

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!
