WebF-ratio. In photography there’s a handy number used to describe the relationship between lens diameter and focal length: the “f-ratio”. Simply put the f-ratio is the focal length divided by the diameter. In Fig 1.3.1 above we have a lens with a focal length of 50mm and a diameter of 10mm. 50/10=5 which gives us an f-ratio of 1/5 or f5.
