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.
I'm also using an E m5 mk2 on macos, with the battery holder grip and 25mm lens. I'm happy with the image but the software is pretty bad, isn't it? There's a substantial lag between the audio and video which is disconcerting to the viewer. And the video stream doesn't reliably start. I usually have to flip the video off and on a few dozen times in the Zoom app before it begins working.
Aside from that the cost of the Very Special USB Cable is a real insult.
I haven't had the same experience at all, perhaps its because I'm on windows? I also don't use my camera as my audio source. I use my laptop microphone for now, with plans to get an external microphone. I just use the usb cable that came with the camera, I never had to purchase it separately.
The battery I use is one that uses the shell of a matching battery but provides a wired 8V DC through a usb SMPS, 20$ from aliexpress and I never have to worry about it.
