A telephoto lens generally refers to a fixed-focus lens with a relatively long focal length and a small field of view. In some application scenarios, users need to observe distant objects. When the objects are of the same size, a lens with a large field of view is often required. It should be pointed out that a telephoto lens is a relative concept. In the field of industrial lenses, ordinary prime lenses are basically 8-75mm, and those with a focal length greater than 75mm can be called telephoto lenses.
