Unlike with most cameras in the compact class, you can attach waterproof converters and 45 mm lens filters to the TG-1 or TG-2 using the CLA-T01 conversion lens adapter. The fisheye converter lens FCON-T01 dedicated for use with TG-1 allows wide-angle shooting without sacrificing the brightness of the f2.0 lens. Even in darker underwater scenes, you can shoot wider, more dynamic images that reproduce the beauty of the underwater world.
