It did not work out. Or rather, I could not get a result I was happy with.

What I tried, take 1

  • Installed EOS Webcam Utility
  • Bought this sketchy adapter that plugs into a power source -> https://amzn.to/3avKj1z
  • Plugged the adapter into a power bank I had lying around and used it as the X7i’s battery
    • Careful not to forget to close the battery compartment door. If the door is open, it will not work as a battery.
  • Connected it to my Mac via Mini-B USB
  • In Zoom, selected EOS Webcam Utility under Preferences-Video
  • The picture shows up, but black bars appear on the left and right.
  • You can crop them out in OBS and the like, but that just feels wrong—would it not be better to simply buy a decent webcam? -> This is where I am now!
  • Apparently this issue is reported all over foreign forums, but in the Japanese-speaking web there are only “EOS Webcam Utility works!” posts. (sob)

Conclusion

It is most likely an issue with the camera itself, so instead of using it as a webcam, I will just use it as a regular DSLR. Better to leave things to the specialists—I will go look for a proper, decent webcam.
