i have two c920s setup and noticed significant focus breathing. it seems to occur mostly when there is movement in the frame. is there anything vmix can do to fix that or is it more a hardware issue?

Most everyone will start by asking this question...

Are you using the Logitech drivers for the camera? If so, you might try removing them.

I would suggest changing the focus from 'auto' to 'manual'. Then, set the camera focus for the shot.

The very fact that he has two C920s setup tells us that he's not using the Logitech driver. It only supports one camera per host. The generic UVC driver allows multiple cameras.

Turn off all auto functions for these cameras.

as he mentioned turn off auto, if you need auto focus on because you're moving back and forth then it sounds like you need to get more light on your subject
