There's a web page on Canon's site here:

https://www.usa.canon.com/internet/portal/us/home/support/se...

You'll see one list of cameras on there, but at the bottom, you can expand "Clean HDMI", and then you'll see a different list of cameras.

Now I'm debating whether or not I want to spend hundreds of dollars for a DIFFERENT photography camera that support clean HDMI.

EDIT - For your case perhaps using camera settings to minimize the data (ISO/aperture/shutter etc) being shown on on the screen works well enough to use what you have?

I saw a few threads with that suggestion, but I wasn't able to minimize the data being shown, or confirmation that anyone with a Rebel T7 was able to do it.

EDIT: I mean it'd probably be OK if I were just shooting a video--I can fumble through it connecting unreliably, or just do another take if it unexpectedly disconnects. But I'm doing multiple video calls a day, and the webcam built-in to my monitor "just works" every time. It's tough to justify the additional complexity for something that isn't working reliably.

That's why I started leaning toward "Clean HDMI". With that method, as long as the HDMI capture device works, everything should "just work" on the Mac side, and as long as the camera can output clean HDMI, it should also "just work." I'm not dealing with a poorly-supported software webcam utility, special USB signaling, or annoying inactivity timeouts.

But it looks like I'll need a different camera, and it won't be cheap, but at least it's an option.

The biggest problem with my setup is that when I open OBS I need to disconnect and reconnect the dongle before OBS will pick it up. Until I figured out how to repeatably get that working it was... more trouble than it was worth. I need OBS because the version of the patched firmware I'm running produces a non standard aspect ratio that I adjust for in OBS, at the cost of a more involved setup and extra CPU utilization. If I used the patched firmware that removes the fixes that (I haven't tried it yet), I would likely forego OBS for meetings.

It should be an AF/MF toggle in the lens.

What I've found is that by USB charging and using HDMI out, it's good for ~2.5 hours of streaming, which I've only ever hit once as a limit.

there's a newer Sony in the same line (the ZV-E10) but it moved the ports to the other side of the camera, so if you flick the LCD round so you can see it, the cables are in the way...

The cheap ones (as little as eight bucks) all use the same all-in-one HDMI-receiver-MJPEG-encoding-USB-device chip; it's not perfect, but they do actually support 1080p at 30 fps.

i found this article https://havecamerawilltravel.com/nikon-d3400-webcam-live-str... that suggests the budget device is workable but obviously doesn't deliver the quality that the camera can provide. but how does it compare to a regular webcam?

The body is old enough to not car about voiding warranties by using a generic battery adaptor and custom firmware.

It's a bit limited in that it only does 1080p30 and it's not the best quality either.
