The specific gear used per YouTube video is in the description of that video.
This is my main shooter, I have used this camera in all of my recent video's. I mostly record in 1080p at 60 fps. The main lens I use is the Canon EF-S 18-135mm f/3.5-5.6 IS STM lens, giving me great zoom flexibility. For wide angle shots I use the Canon EF-S 10-18mm f/4.5-5.6 IS STM lens.
This is my older secondary camera, I still use it occasionally when I need two camera angles at once. Depending on the specific needs of a video I will either shoot at 720p 60 fps or 1080p 30 fps. The lens on this one is the one included in the kit: the Canon EF-S 18-55mm f/3.5-5.6 IS II.
I use this shotgun mic in most static shots, for example in "The problem with smart lights". It's pretty affordable and in my opinion sounds great!
I use this combination whenever I'm not using the shotgun mic. It doesn't sound as good as the shotgun, but is a good alternative for example when I'm moving a lot like in a VR game.
