Zoom lens

Definition

A zoom lens is a type of camera lens that allows the photographer to change the focal length and magnification of the image without having to change the lens itself. This versatility enables filmmakers and television creators to manipulate visual style and tone by adjusting the framing and perspective within a scene. By employing different focal lengths, a zoom lens can convey emotions, focus on details, or establish context, significantly influencing how viewers perceive the story.
