Recommendation for a high-quality webcam for Linux
Recommendation for a high-quality webcam for Linux
I have a Logitech C920 and am looking to upgrade. Something suitable for streaming.
Some annoyances with the Logitech: sometimes autofocus fails and poor reproduction of blacks. Ex: Lack of detail when a black cat is on screen.
I already have a nice mic-- the webcam doesn't need one.

Wow, I've used a C920 and now a C930 and never had any issue, although I just do meetings.
I'm interested on seeing opinions too.
C920 is good enough for meetings. I solved the focus problem using the traditional Linux method of writing of udev rule which launches a timer when it's plugged in, which periodically launches a systemd service, which runs a bash script to make sure it self-corrects at least every 5 minutes.

I remember that once it was permanently stuck out of focus but unplugging and plugging again fixed the issue. Never had any other issues in years.
My c920 now glitches out and refuses to stream video after about 10 minutes of use (mic still works tho). After some unknown long period of time, it resets and works for another 10 minutes
Yeah mine's doing that too, and my dmesg is flooded with USB disconnect and reconnects.
The thing probably is overheating and shutting off. I believe I've seen videos of them catching fire too, not sure if it's that one or another webcam that looks similar.
Mine's on a USB hub with buttons for each port so I just leave its port off until I need the camera and only turn it on when needed.
I have a c920 and it's complete poop. Random hiccups and stutter and the auto focus fails.
