By understanding it, it will be easy to figure out why the aperture opening f/4 is larger than f/16. If you choose f/16, the diameter of the opening will be 5mm (80mm/16). So, the diameter of your aperture blades is 20mm across. If you choose f/4, you will get the fraction 80/4. Let’s imagine you are using an 80 200mm f/2.8 lens completely zoomed out to 80mm. If you replace this f value in the fraction with the focal length value, you will get the diameter of the aperture. The “f” in “f/22” stands for “focal length”. So, I am trying to give you a simple explanation. Sometimes the beginning photographers don’t understand what the “f” stands for in f-stop and the name of aperture (for example, f/22).
