Lol. Data is based on 5 films. So clearly these films are using multiple types of cameras. But that also implies that all or nearly all of them shot on film. And I would assume that their main cameras were shooting film. It's definitely a statement that this is where we are so long after the introduction and popularization of digital cinema cameras.
Update: this chart is wacky. I looked at the article. Basically 3 movies shot on film and 2 on digital. The brutalist used both arricam st and arricam lt so that's why the arricam gets a 4 count and not a 3 count.
