Maybe because digital very quickly wiped out film as a consumer product but still hasn’t conclusively matched it for overall quality in key pro applications. So digital has amounted to a 20 year market powered by incremental but significant improvements.
Dynamic range and related “color science” matters seem to be the last hurdle and better DR powers a lot of new sales among videographers, especially at the low/accessible end.
35mm film offers about 13 stops of DR. To get this on a digital you’re looking at a $2-$3k DSLR or Blackmagic or whatever. The latest iPhones are reportedly 9 stops.
