Film Cameras

[tayl0124]

Okay, not really a question about film but rather film camera's. What is the real difference between different models of film camera's. I understand that with digital a big portion is sensor size and light handling, but isn't that mostly up to the film (and lenses) used in a film camera?? The reason I ask is that my late grandfather has/had a canon eos 620, which I can tell is much nicer than my rebel g. But what really makes them so much better???
