The Vintage Wollensak Velostigmat Wide Angle Series III f 9.5 Lens is a classic photography accessory with a brass lens barrel and a maximum aperture of f/9.5. Known for its high quality and durability, this wide-angle lens is designed for fixed prime focal lengths, making it ideal for capturing sharp and detailed images. With the Wollensak brand reputation and unique design, this vintage lens is sure to enhance any photographer's collection and bring a touch of nostalgia to their work. As I know nothing about photography or camera lenses, this lens is sold as-is.
