As stated somewhere else, at the end the video will go through very lossful compression and often be scaled down when used at work. I mean I'm now at my 4th webcam since the pandemic started because the other cams were: too dark, constantly zooming in and out for no reason (MS Cinema Lifecam), poor image. I now sticked with the Logitech C920 because I can manually set brightness/contrast/activate autofocus.

I think that understates how bad the current state of webcams really is. Esp. when you move around a lot while talking/there's an unusual light situation. IMHO first these core problems need to be solved (and then of course it'd be great be build upon that)

Bigger sensors and bigger lenses are exactly what would solve those core problems. Even after video call compression (which is not always extreme) it is trivial to tell whether a video was taken with a big sensor/lens or a small one. Compression is no reason to use a crappy camera. Garbage in, garbage out.
