Re:Using a "proper" camera as a webcam

This looks like it should compare favorably to the "real" camera + HDMI capture card solution. The lens is always the most important part of any camera setup, so if you get the right lens, you're probably gold.

In my case, the "lens" is a microscope objective and a long tube, but I've also tested it as a webcam.
Arducam has a bunch of C-mount lenses, https://www.amazon.com/stores/page/35052708-55DC-4832-A0B6-A... as well as nice USB webcams that let you choose from several sensors. https://www.arducam.com/sony/imx477/
Ehh. After a certain point that's true, but a lens doesn't help much with a garbage sensor, particularly one that has to be compensated for with huge exposure changes. (This is the core of why webcams are disappointing, not the lens.)
I use a GH4 or G9 with a USB3HDCAP at my desk because I already have them and the glass, personally, and I know the sensor is not going to be a trailing problem behind the (cheap!) glass that I use.
The sensor is an IMX179 which is a mainstay. I believe the sensor area is smaller, and probably higher noise than a DSLR or mirrorless, but for VC use, it's probably not going to make a difference.
