I am someone who is a photographer on the side with $X0,000 of gear. I've also even experimented with a DSLR and prime lens as my webcam of choice (with the EOS Webcam utility). But now? Logitech MX Brio or something like the Dell Pro Webcam. I use the Brio and a Yeti X microphone. Crystal clear audio and video. 4K video is overkill for remote work, though the downsampling helps. I don't believe any of the major meeting software will even share your video at 1080p (or if it does, only by tweaking multiple switches AND by your counterparties having both the bandwidth and similarly tweaked switches). There's investment, and then there's overkill, which even as someone with GAS (gear acquisition syndrome) I see here.
