Cam Link 4k HDMI Camera Conn. : Flawless

This is the hottest product in the world just now so you probably know what you are looking for...like most people, i got this to make my videoconferencing experience better.

I'd previously been wrestling with the BlackMagic Ultrastudio - which is an excellent piece of kit (probably technically more advanced than this - certainly more "pro") but I really struggled to get it working. Swapping between apps always caused some weird settings nonsense to happen, and I had the sense that my (2018 Macbook Air) laptop just wasn't meaty enough to power it.

I got the Camlink - spent half an hour trying to find the software you need - turns out you don't need software - and it was flying. Doesn't seem to cause the laptop more stress than the logitech webcam it replaces, works super easily with either of my SLRs or any camcorder we've tried. Highly recommended - but you knew that anyway :-)
