What is Focal Length Ranges?
Focal length range refers to the range of focal lengths that a camera lens is capable of producing.
Focal length is the distance between the lens and the image sensor or film when the lens is focused at infinity, and it determines the angle of view and magnification of the lens. A lens with a shorter focal length produces a wider angle of view, while a lens with a longer focal length produces a narrower angle of view and higher magnification. The focal length range of a lens can vary from lens to lens, with some lenses having a fixed focal length and others having a range of focal lengths, such as a zoom lens. Zoom lenses typically have a range of focal lengths that can be adjusted by the photographer, allowing them to achieve different angles of view and magnifications without changing lenses. The focal length range of a lens is an essential factor to consider when choosing a lens, as it affects the flexibility and versatility of the lens for different photographic needs.
