The f-number/f-stop is the ratio of the lens focal length to the corresponding lens aperture (or opening through which the light passes). Of course, the amount of light captured at the focal point (where the CCD or CMOS sensor resides) is directly proportional to the size of the aperture—the bigger the hole, the more light that comes through. However, all of the values (FOV, focal length,
