Lens Operation Noise With EOS M

I'm relatively new to video. I received an EOS M kit including EF-S to EF-M lens adapter for Christmas. With the 18-55mm STM and 22mm f/2 STM there is no lens operation noise (focusing) but with my EF lenses, including my 135L, the background noise from lens operation isn't acceptable. I'm using an external hot shoe mounted microphone by the way.

I've been trialing the 135L, EF 85mm f/1.8, EF 50mm f/1.4 and Sigma 50-150mm f/2.8 non OS. While I find the image quality outstanding with these lenses, the lens operation noise isn't so crash hot.

Any solutions?

Are you manually focusing? or focusing via the shutter button?

The STM lenses are built to be quite and for continuous video autofocus, regular EF lenses are not. There are EF-STM lenses like the 40mm pancake.

Using auto focus. I prefocus using the shutter button then hit the video record button which also activates auto focus.

I'm thinking of moving the microphone off the camera and mounting it via a small boom to my tripod.

You really should not be using auto focus when shooting video.
