Just bumping this post. Anyone know? Thanks!

Can’t confirm 100%, but 99,9% sure that we saw realtime autofocus data from the c400 in Aximmetry. Just make sure you use a supported lens. Not all of them are supported and not all supported lenses are listed either. 

Thanks Johan, would love to try to get some kind of confirmation on this if possible! Are you still working with that camera or could you point me in the right direction to someone who is using the canon cameras/lenses with Aximmetry? I'm trying to decide is I will get into the Canon ecosystem. Their integration with Virtual Production workflows is a huge selling point for me. If I can confirm the autofocus is working, I will likely make the investment. 

You should contact Canon directly about your if you need 100% confirmation. Just worked with the camera in another studio, so don’t have access to it.
