The FCON-T01 Fisheye Converter Lens from Olympus is dedicated for use with the Tough TG-1 iHS digital camera and allows wide-angle and panorama shooting without sacrificing the brightness of the f/2.0 lens. Be creative with its19mm focal length (35mm equivalent) and 130º angle of view. Even in dark underwater scenes, you can shoot wider, more dynamic images. The CLA-T01 Adapter is sold separately and is required to use the FCON-T01 Fisheye Converter Lens.
