Focusing: It is the adjustment process of changing the distance between the objective lens and the object to obtain a clear image of the object.
Aperture: Aperture is a device used to control the amount of light passing through the lens and entering the photosensitive surface in the fuselage.
It is usually inside the camera. To express the aperture size, we use f value. For the lens that has been manufactured, we
It is impossible to change the diameter of the lens at will, but we can add polygons or circles inside the lens to

Focus: The process of controlling a beam of light or particles so that it converges as much as possible at one point. For example, convex lenses can flatten
Traveling light is focused at the focus of the lens; magnetic and electric fields are used in electron microscopes to focus the electron flow; thunder
Da Da uses concave mirrors to focus very high frequencies. Focus is a necessary condition for imaging.
Note: The desired imaging effect is achieved by changing focusing, aperture, and focus.
