If you didn't use "Right" in your text, I would not have to defend my teory and blabla bla bla bla... In numbers prehaps you have more "tonal-range" etc etc with your film camera, but than again you have to face THE Scanner, and end up with a final image that is a poor copy of the original, before facing THE realtime decompression. In my opinion the difference between both (35mm film and good quality digital cameras) "if exists" is so little that does not justify all the films, scanning, ASA change etc etc involved in the process.....that ends with a small window showing a real time moving image with a 25-50% compression.
