This is an amazing, cheap, fun way to experiment during quarantine, you only need some garbage bags, as explained in the video, the Bonfoton lens is just a way to get a sharper and brighter image for photography and videotaping the room, but it will work even without it. I was not paid by Bonfoton, I just think this lens is great and it's made by hand in Finland by two people : https://bonfoton.com
