    Hello. Planning on moving up to Prosumer Land, so, of course I’m looking at the Scarlet 2/3”. Right now I’m giving myself a crash course on DSLR lenses to try to understand how this kind of thing works.

    1. Can anyone please provide me with some links describing how 35mm type lenses compare/contrast with 16mm type lenses?

    2. On a 16mm film camera, is the film closer to the base of the lens than on a 35mm film camera? If I just knew this, much of this stuff would start making sense.

    3. If the film is indeed closer to the base of the lens in a 16mm film camera than in a 35mm, would you suppose that the RED Scarlet 2/3” would have about the same distance from the base of the lens to the sensor as a 16mm film camera has between the base of the lens to the film, and that the Red One would have about the same distance from the base of the lens to to the sensor as a 35mm film camera has between the base of the lens and the film?

    4. Is a 16mm type lens projecting the same amount of light onto/around the sensor as a 35mm type (with the 16mm just projecting the light into a smaller space), meaning that the 16mm area is getting much more light than the 35mm area (with lenses that provide the same field of view and amount of zoom)? Could one then use less sensitive sensors to achieve the same low light performance? A clearer way to ask may be, on 16mm film cameras, do people tend to use slower film (lower ISO) to get the same low light performance as on 35mm film cameras? (I know it depends on the lens, but I'm not yet sure how to compare 16mm and 35mm type lenses).

    Many thanks,
    Chris

    Since your questions are more geared toward how the RED Scarlet is going to be, I'd suggest asking your questions over at reduser.net.
