If you go this route, please make sure your system is robust and ready to go before meetings. We had to ask one employee to go back to his reliable built-in webcam because every other meeting started with 2 minutes of him getting his camera turned on, messing with audio inputs, getting his microphone boom in place, and fighting other quirks. He also had a tendency to drop out of long meetings when his camera overheat…

… I mean, that's Bose QC headset's & macOS's relationship with Bluetooth, in a nutshell.

Heck, I've had to fight to just get the onboard to function, particularly so in MS Teams.

I'd love to see stats on how many people actually still use webcams for online meetings. I rarely do, and I don't care if anyone else turns theirs on. Watching someone act like they aren't hyper-aware of what they look like on camera adds very little value to the conversation. Unless you're in sales, trying to make a good impression, or some kind of introductory meeting, who cares?

I have an alternative approach that I discovered recently while building a microscope with a webcam driven by linux. Nearly all modern cheap webcams are UVC-compatible and they work with linux. Different models expose different functionalities, but I ended up with this: https://www.amazon.com/dp/B07R489K8L It does 1600x1200 25FPS YUYV (as well as a wide range of other resolutions and FPS) uses the C/CS-mount lens sta…

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.

If you're willing to throw $1000 at a "proper camera" of the sort the author recommends, then sure, it would be very disappointing if it didn't outperform the webcam built in to most laptops or phones. But is there a "proper camera" for under $100 that can also offer an improvement over a webcam?

Canon's EOS Webcam Utility supports cameras down to the EOS 1100D, which, depending on your level of luck, you can find used under $100. Then all you need is a kit lens which can be found for very very cheap nowadays. Or, if you really think you won't be moving much, just get a super cheap vintage one.

It's under 10fps for most of the cheap models. And unless you don't move at all the focal point of the kit lens is going to make the video almost useless. Autofocus on these cameras can't follow as fast as necessary for live video.

I have played with EOS webcam utility in the past and if you are not ready to spend big, DSLR is not the way to go.

I'm surprised no one has mentioned using a teleprompter yet. You can pick one up for around $100 and when combined with a little 7" monitor (another $100) attached to your computer, creates a nice setup for zoom calls where you can look directly at your partner. Also doubles as a great talking head setup for video production.

I second this! I’ve been using one of these as well, and I’ve noticed the positive impact looking directly at the camera can have on my conversations.

Do either of you have a shot of what this looks like in practice? Google Images isn't giving me much. Specifically what the Zoom or Meet looks like from your perspective.

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.

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/

One thing that I’ve been trying to educate my colleagues about (including the A/V folks!) is that one can bypass the need to fiddle with drivers by using a generic hardware HDMI -> USB video conversion stick utilizing the mirrorless/DSLR’s HDMI output. It’ll mount as a generic video input that Zoom/Teams/OBS can use. You can find these for $40-$100 and it allows one to switch out hardware brands at will without insta…

This is the method I use, in conjunction with the Sony ZV-1 which gets a mention in the article. It also bypasses the problem mentioned in the article about turning up as a mass storage device. 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 othe…

With my a6300 I actually managed to get a week (!) of constant streaming and USB charging out of it. I use a USB data blocker to enforce USB charging only, it works incredibly well.
