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 surprised that things haven't started to level out yet.

> 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.

The trick to great picture quality is to use good lighting and drop the ISO on the video as low as possible. I've been using Reincubate Camo for my iPhone along with Key Light Air Lights. The quality is better than any webcam. Most webcams crank up ISO so they can work in the dark and that is what ruins picture quality.

> It's easy to buy some "random" sensor that was around for years and most certainly has "meh" quality by today's standards, but we need a good one, with good dynamic range, HDR capabilities and low-light performance.

So maybe it's a matter of time until these "good" sensors reach the open market, can be bought in smaller quantities and become commoditised. Then, we may see a good upmarket webcam.

I can't say the same about my experience with (other people's) webcams.

From all the video calls I had this year, people either used

* their notebook's built-in webcam that's complete garbage

* any other webcam, and their image is clear as day, or at least video quality is limited by lighting or bandwidth.

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?

I think the author lost me when they said that a good webcam has to have "decent sound quality" and uses the MacBook as an example. I have literally never seen anyone suggest using your webcams /laptop mic except as a last resort.

Macbook Pro mic is literally much better than most webcams mics right now.

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' imagery for streaming/recording right now is to buy a second hand DLSR or mirrorless camera that has 'clean' HDMI out that works without the camera auto-shutting down after X amount of time. There are a few sites out there that list the preferable models[1]. I've got a couple of old Canon DSLRs (That don't do clean HDMI) and a load of lenses, so I've been watching Ebay for a newer model Canon DSLR that I can afford. The lowest cost Canon DSLR body I've seen with unrestricted clean HDMI or that can take the Magic Lantern[2] firmware is about £150.

However... You also need a HDMI-to-USB dongle. This converts the cameras HDMI output into a standard USB Webcam input. I've already got an Elgato CamLink[3] (bought for a different reason a couple of years ago), but you can get cheap China knockoffs for about £15, I don't know how good they are though. My Camlink cost WAY more than that, so I have my doubts about the knockoff quality.

Finally, you need good audio capture that importantly is in sync with the picture. The HDMI to USB conversion adds a tiny delay to the image which can put your audio out of sync if you are using a standard USB microphone. Good software like OBS[4] can correct for this though.
