I have a question, why was S35 created anyway? What was the driving force behind the idea to create it? I'm just curious.
Because conventional 35mm does not expose the area historically used for the optical soundtrack. Since sound is not recorded to film during production this negative area is, in a sense, being wasted during photography. By optically realigning a camera to fully expose the negative filmmakers end up with a larger exposable area, and in theory a superior image due to using more negative.
Of course, as our discussion indicates, S35 is utilized diversely.
Some very popular uses are shooting for telecine, such as TV shows and commercials and for HD programming, because you can compose either 1.33:1 or 1.78:1 with the largest exposure possible with conventional 35mm movie cameras, and superior to any video acquisition format. For such applications, with spherical lenses, fine grain stocks, and achieving a dense negative, you can produce the sharpest images possible with 35mm movie cameras if that is your intent.
Regarding ~2.40:1 for theatrical presentation, it affords some benefits over shooting anamorphically. A major one is cost. Anamorphic lenses cost more to rent. They are also slower than spherical lenses, which means that you may have to spend more on lighting equipment. They are also heavier than spherical lenses. So, anamorphic lenses means more equipment and more weight and more money. The photographic attributes are very different between anamorphic and spherical lenses. Spherical lenses are (quoting Panavision here) "superior in definition, contrast, freedom from distortion...", and the fields of view are quite different (50mm for 2.35:1 anamorphic is equivelant to under 25mm for spherical 2.35:1). Anamorphic lenses can't achieve the same depth of field as spherical lenses at comparable fields of view. As someone else noted, you could never have achieved the remarkable cinematography of Citizen Kane with anamorphic lenses. Also, shooting ~2.40:1 on 3-perf S35 will use 75% of the raw film stock that shooting anamorphically would, a remarkable conservation. As I noted previously, it would also be impossible to reveal a 1.33:1 open-matte transfer from such a camera negative. For some filmmakers, the cost savings alone fascilitate their making the film at that AR. There, now I answered my earlier query to Jeff about why filmmakers may choose this method
Incidentally, the method, while not always called Super35, has been in use for a long time. Hitchcock used it, as Robert Harris once informed me.
