Film Camera Gates vs. Digital Sensor Sizes - numerical data

Film Camera Gates vs. Digital Sensor Sizes - numerical data

I was going through some old research the other day and found something I made that I feel is worth posting here. It's basically a table that lists the physical dimensions of various film camera apertures and video camera sensors. Awhile back I was trying to find a "normal" lens size for each format, i.e., in Super 35 a "normal" lens is considered to be a 35mm. Of course by "normal" lens I mean, one that basically recreates the natural, undistorted perspective and field of view of the human eye.

This is determined by measuring the diagonal distance of the imaging area (sensor or aperture). A lens size that corresponds to this diagonal distance in milimeters theoretically should recreate an undistorted Field of View. In practical application the actual dimensions of 1/3" and 2/3" camera sensors varies widely from manufacturer to manufacturer. The "1/3" and 2/3"" label are used more as a camera classification than an actual size. Therefore, there really isn't a way to accurately systematize and correlate lens sizes and Field of View to video camera sensors. This information can help get you in the ball park though and is useful for finding equivalent lenses across various formats.
