I think this is an excellent piece of dialogue and an attempt to communicate.
I especially like your point about the cheaper-cameras and film, that somehow this is always been this way. Very similar to when someone is trying to simulate an old movie, what is the first thing they do? Add scratches, like old film has always been scratched and not because it was improperly stored. Many older cameras are fine-quality machines (some newer ones too!) and the quality of film has never been better.
Very nice response!
