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.
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.
