A Zoom Lens is a type of camera lens that allows the photographer to change the focal length, enabling them to zoom in or out on a subject without changing the lens. This versatility makes it easier to capture images at various distances, from wide landscapes to close-up portraits, all with one lens. Zoom lenses are commonly used in photography and videography, providing convenience and flexibility. They come in different ranges, such as wide-angle to telephoto, and are popular among both amateur and professional photographers for their ability to adapt to different shooting scenarios.
