Best webcam under 100 dollars for video calls?

honestly the biggest upgrade under 100 isn't the camera, it's a cheap lamp in front of your face. any webcam looks grainy in a dim room. that said, the Logitech C920 is the boring safe answer, it's been around for years, usually sits well under budget and the exposure and autofocus behave. Anker's PowerConf C200 is the other one people seem happy with at a similar price and copes a bit better in low light. skip anything advertising 4K at that money, it's a tiny sensor doing more work. lamp plus 1080p beats 4K in the dark every time.
