The number is calculated by dividing the focal length of the lens by the size of the aperture. Since lenses are designed with changeable apertures, the f-number changes as the iris is opened or closed.

The focal length of the lens also affects the way a captured scene will look. This is known as the angle of view, which we will discuss later when we explore types of lenses.

They have combinations of concave and convex surfaces that move in relationship to one another to create different angles of view through the lens.
