Wide angle lens generally refers to the Fixed Focal Length Lenses with large field of view. In some applications, users need to obtain a larger field of vision, and they often need to use the lens with a large field angle when the working distance cannot be changed. GU's wide-angle lens has a large field of view, which is suitable for large FOV applications
