I am a set designer working in the film industry and using 3d models to show directors, production designers and cinematographers what they would see by a particular lens. I know there are MANY lens packages, but can someone give me an idea what lenses are the most "popular"? I am referring to the wide angle lenses. I know this is a difficult question, but what wide angle lenses are likely to be used -- and at what point do they begin to distort so much that they are rarely used. For example, Stanley Kubrick uses wide angle lenses a lot in his films. How wide would he go?
