What is a fixed focus lens? What is its function?

As the name implies, a fixed-focus lens is a lens with a fixed focal length. ?

Generally, fixed focus is rarely used in indoor shooting. Unless your studio is big enough. ? Fixed focus is most suitable for shooting location, because the zoom image quality is not as clear as fixed focus when shooting without flash, and it has the advantage of wide-angle lens.

Generally, the focal length of the lens we use can be changed.

That is, you can zoom out the object and zoom in into the camera.

Fixed focus, as the name implies, is a lens that cannot be zoomed.
