Swell, the 1D X Mark III can be used as a webcam now. Woohoo!

But seriously, a few years ago I was wondering if it was possible to use a DSLR to - say - livestream stuff, which would've been better than using a cellphone's horrible sensor and lens. Back then, I had no answer to that. I may end up downloading and trying that software seeing as how my second camera, the 80D, is on the compatibility list. Not immediately sure what a "T6i" is in proper naming conventions, but if it's really the same as the 650D that my wife has, it's also eligible. (upd: NVM, it's the 750D. I hate these pointless US market-only names for the Rebel cameras because... well, because they're pointless)
