And so the numbers around the f-stop correspond with the size of the opening which is letting light to your camera. F-stops are measured by the scale, which is called the f-stop scale. If you are not knowledgeable about a camera, the f-stop numbers can be quite confusing as they don’t apparently make any sense. The f-stops have been a measurement in the diameter from the aperture. Logically, they must be expressed as a fraction and this number would let you know the diameter in millimeters as a fraction of the actual focal length in the lens.
