Extra note here, I've been running my olympus em5 mk-2 with the drivers Olympus released to run it as a web camera and its been working just fine, out of the box. I got an extra dummy battery to power it (cannot be powered though usb) so I have no worries of it dying during a long meeting.
in a remote office world, I'm glad my team leaves their cameras on and I view it as a form of professionalism to present myself as best I can, and if that's not following a dress code and keeping trim in an office, its giving good video quality in online meetings.
