> So there is a market gap between so-so webcams for $100-200 and a full-blown setup with a mirrorless camera, an external mic and lighting panels that will cost almost a grand or two, if you're so inclined. Nope. You can get a mirrorless camera set up (with mic and lights) for around $500 to $600. There are plenty of 1" compacts as well in that price range.

Can you mention a specific models that would work well in this use case?

oh yeah, the webcams suck big time. even the expensive ones. just get a dslr over hdmi. it's 100x better and used dslr is cheap these days. you can even get panasonic gh4/5 which is a real video camera.

Can you recommend any dslr models or what to look out for when buying used with the intention of only using it as a webcam?

Canon M200, Panasonic G7, Sony a5100 (oldest but can be bought for cheap and has good autofocus).

I use https://www.elgato.com/epoccam on my iPhone and for a few dollar is far superior than every webcam I've tried in my life.

Similarly, and multiplatforms, I recommend DroidCam ( https://www.dev47apps.com/ ). The interface could use some polish but it works well on android/ios phones to Mac/Windows and Linux.

What's your lag with Droidcam?

My experience was a delay of half a second, making it unusable for live conferencing.

You actually want a mirrorless camera, not a DSLR one. If you intend to only use it as a webcam, probably just buy Panasonic G7 or Canon M200 for $500.

My entry-level Canon DSLR (EOS 550D) can stream over USB, although it's not "plug and play", at least not on Linux. To make Chrome detect it as a webcam I need to go through gphoto2 -> ffmpeg -> v4l2loopback pipeline.

A year ago, you could easily buy a good webcam for very little. The Logitech C920 is, to my eyes, superior to the MacBook Pro webcam, and offered at least semi-decent audio quality. Pre-pandemic, it could sometimes be had for £25 (~$35). Post pandemic, however, webcam prices seem to have at least tripled (if not quadrupled). As I type, the C920 is going for £140. I can understand this as a supply/demand thing, but su…

C920 is still only mediocre IMO. It's ok if you sit completely still but it doesn't handle motion at all.

I've also investigated this quite deeply. As I'm sure most of us know, the main problems with 'webcams', either the built-in ones or USB ones that you perch on top of your monitor, are the lens size, and the CCD/CMOS image sensor size. Manufacturers spouting specs like '4k' are deliberately misleading the public if the sensor and/or the lens aren't also upgraded. The only cost-viable methods to get 'broadcast quality…

I have a similar setup but don't you find the latency to be bad? At least it's not good enough for video calls IMO. It's fine for streaming to an audience or recording.

Sony's A6000 works perfectly well, but I recommend you also grab a NP-FW50 dummy battery as it will drain the battery even when plugged in via USB over time.

If you want better sound, grab the A6600 which can also sport the XLR-K2M microphone adapter.

Regarding HDMI capture: the Blackmagic DeckLink card series works just fine in a Thunderbolt case (at work I run a 2x A6000 system + external HDMI input).
