Tell us more. You use Nikon's software and what else? Mac or PC?
Yes, I'm using Nikon's webcam utility (currently in beta testing). Simply install it on your computer, and whatever video conferencing software you're using will see your DLSR as viable webcam option. As far as the lens is concerned I'm using the Tamron 24-70 f/2.8 G2 on my D850, typically around 35mm. I also run audio off camera with a Rode shotgun mic directly into the PC.
I recently heard a Nikon rep indicate that it's now available for Mac too, but I don't see it as a download option on Nikon's site yet.
Personally, I set up in my blacksmith shop since I have plenty of room out there. With a fire going and all the equipment it provides a unique background that everyone thinks is a digital replacement background.
