These two lenses, the SGW-05 (0.5X wide angle) and the SGT-20 (2.0X telephoto) are designed to work with compact digital and
analog camcorders having a 37mm filter thread. Each greatly expands the zoom features of the camera - the wide-angle will double your field of view while the telephoto lens will double the optical zoom, getting twice as close without resorting to a digital telephoto mode.
