Variable focal length

Variable focal length refers to a camera lens's ability to change its focus distance, allowing you to zoom in on distant objects or capture wide scenes without changing lenses. It works by adjusting the lens elements to modify the focus point and magnification, giving flexibility in framing shots. This feature is common in zoom lenses, enabling photographers and videographers to adapt to different scenes and compositions quickly, providing both close-up details and wide-angle views with a single lens.
