Earlier quoted context omitted.

What camera did you end up with that had a narrow FOV?

I can recommend a full-frame Canon RP ($999) with RF 35mm f1.8 lens ($449) as a relatively inexpensive narrow FOV setup. Edited to add: Meant Narrow DOF when writing this, but both are true if you sit close to it!

OP here was referring to webcams with narrow FOVs

I don't understand what's wrong with the Logitech C920's output there. He has plenty of light, so it's a decent image. He talks about video calls and not video production (YouTube, etc...). How great do the video calls need to be?

And I get it, to each their own, but it just seems overly complicated.

I think as long as you have good lighting, something like the c920 is good. I have a Razer Kiyo Pro and it's good too. My biggest issue is lighting. I have blackout curtains to keep heat out so my office is dark. I need more front lighting. Even an expensive set up like the article wouldn't help much.

I've had to talk myself out of pulling the trigger on this several times. It's such an obvious level-up compared to how horrible most webcams are – but I just don't need it, and I'm unlikely to use the camera for anything else.

I did spring for a nice software-controlled key light[0], and it makes a huge difference. It basically compensates for the fact that my home-office location has the worst lighting conditions, with a bright window directly behind me and another to one side.

For video, I think this is a waste of time and money. Audio is a different story.

The quality of your audio has an impact both on the intelligibility of what you're saying and on listener's subconscious evaluations of you. Audio software and hardware is also cheaper and much, much easier to deal with than video--I've had no problems with essentially the same setup across Mac, Linux, and Windows.

The cost of entry is somewhere around $50-$100 for USB microphones, although if you're willing to spend closer to $250, you can get a decent USB audio interface ($120) + standard (XLR) microphone ($100) + XLR cable ($10) + stand or boom arm ($20).

I've been in countless online meetings where I'm barely able to hear one or two of the participants.

Every time I've evaluated a better video setup, it's been clear that there are a bunch of things you want to get right in order to have a smooth & reliable experience. You want a camera with clean HDMI output, a capture card, and make sure that your camera can be run continuously for as long as the meetings will last--don't forget back-to-back meetings. If you might be in meetings for three hours in a row every once in a while, do you need a camera that can be run for three hours continuously? Most "proper" cameras just can't do that. If you dig into the specs, some of them will list the maximum amount of time that they'll run before shutting off. Twitch streamers and people who run YouTube channels have done the research and will tell you which cameras are suitable for this kind of work, but at that point, you're often spending like $700 or more just so people can see a clearer picture. I would love it if I could just use my DSLR, which is a very nice prosumer DSLR with some nice lenses, but it's just not designed for streaming video. I would have to buy something new.

High-quality audio for $50-$100 is a much, much better deal.

Only tangentially related but if you already have a popular Logitech webcam (like the C920) chances are you can find a kit to mount C/CS/D-mount lenses on it, like with this one: https://www.kurokesu.com/shop/C920_REWORK_KIT2 C/CS/D mounts are for CCTV camera so you can find new and used lens for cheap. They will not fix a cheap/bad sensor, but they will definitely get you extra flexibility in what kind of framing/sh…

With these kits do you lose the ability to autofocus?

This right here is the best solution I've found. I have their Brio kit w/2.8-12mm CS lens and it's excellent in a small package. Low light conditions are still a challenge due to the tiny sensor. As a bonus, you can disconnect the built in mics and opt for a nice boom mic with a hardware cut off switch.

How would you disconnect the built in mic?

Protip: if your goal is to use your smartphone as a webcam, check out this: https://vdo.ninja Written by some guy named Steve, it’s an incredible piece of web software that uses WebRTC to stream phone audio and video as an OBS input. OBS then features a virtual webcam capability to take that stream and make it a webcam. I can then also use OBS to do whatever processing I want, e.g. making my webcam also contain a scr…

I use something similar to stream video from a Pixel phone over USB to OBS (Droidcam). I tried doing it over WiFi but the latency is better over a wire.

I had a similar setup, and it was a pain. It was flaky and clunky.

I switched to a Logitech Brio, and have been very happy. It's almost just as good, with no hassle. Highly recommend for anyone looking for an upgrade without wanting to go all-in.

I would like to have the ease of use of a webcam (plug it in via usb and it works), and the quality of a dedicated camera. And a possibility to make some presets (focus, zoom, crop, white balance), that are on by default and can be switched easily.

It doesn’t have to be perfect, just better than a standard Logitech Webcam. If it would be in the quality range of an iPhone camera, I would be super happy.

Any ideas what to buy?

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…

Honestly the video adds pretty much nothing to a Zoom meeting. You're better off without it. Maybe it's different for managers/executives but for engineers it's more of a distraction. People built Linux over email. Having audio meetings is more than enough.

Even for streamers, audio is _much_ more important than video. You can have a potato webcam and get by, but if your audio sounds like crap nobody is going to stick around at all.
