What is a pan-focus lens?

A pan-focus lens is a special kind of lens, which is characterized by the fact that when the shooting distance changes, the focus position does not change, which is called "pan-focus".

The lens has a wide range of focal lengths, allowing clear images to be obtained at different shooting distances. Pan-focus lenses are used in a wide range of application scenarios, such as news photography, advertising shooting, etc. Since the focus position of the pan-focus lens remains unchanged, when the shooting distance changes, the photographer can adjust the lens angle or change the shooting angle to ensure the clarity of the picture.
