  2. Nice I also share with you something hope this helpful for you my friends. The size of the opening, which is regulated by a series of fins encroaching from the edge of the lens barrel, is measured in so-called f-stops, written f/2.8, f/5.9 and so on, with smaller numbers denoting wider apertures. If you find this inverse relationship tricky to remember, imagine instead that it relates not to the size of the hole but the amount of each fin encroaching into the opening. A narrow opening is regulated by a large amount of each fin encroaching into the barrel, and so has a high f-stop number, such as f/16, f/18 and so on. A wide opening is characterised by a small number, such as f/3.2, with only a small amount of each fin obscuring the light.
