When I see something described as a "film camera" I infer that it uses film.
This appears to be a "film-quality, cinematic camera" that does not use film.
I had to read the whole article, carefully, to be certain that the project is purely digital. It looks digital, there's no obvious place to spool film, but phrases like "film is recorded RAW at extremely high quality" really muddy the waters.
So for anybody who's wondering, this is a digital camera.
