I'm primarily a stills photographer with some great interchangeable lens camera gear. But now in 2020, I find myself needing a webcam for video conferencing under lockdown. I'm frustrated by the lack of webcam gear available, and the lack of quality in the gear I *can* get my hands on, all while sitting on top of some top-grade *video-capable* photo gear.

I'd really like to use my nice expensive—controllable—interchangeable lens gear for video conferencing, but I'm not sure how to do it. How do I tell if this is possible with my gear, and what will I need?
