“For example, this Canon M50 Mark II, I have a Viltrox speed booster on there, which gives it more of a full-frame look, and I have a Sigma 20 mil f1.4, and as I mentioned, this camera is kinda broken, well it's obviously working, I'm recording with it right now, but the back LCD does not work so I have an external monitor attached to it so I can reference that.”
