A wide-angle lens is a type of camera lens that has a shorter focal length than standard lenses, allowing it to capture a broader field of view. This makes it ideal for photographing landscapes, architecture, and large groups of people, as it can fit more into the frame without needing to step back. These lenses typically have a focal length of 24mm or less in full-frame cameras. They can create a sense of depth and perspective, making objects in the foreground appear larger while still including more of the background. This effect is often used in photography and cinematography to enhance visual storytelling.
