This is a set of the underwater housing PT-056 and wide conversion lens for the OLYMPUS TG4. The lens is magnetically attached for easy enjoyment of both macro and wide-angle shots. (The original screw-in parts are also included.) The housing has never been submerged. It hasn't been used for a while, but it was stored with silica gel, so there is no mold inside. (Extra silica gel is also included.) The wide conversion lens has some scratches. They don't significantly affect the photos, but please purchase only if you understand this. In addition, an adapter for attaching a light is also included, so you can use it for a wide range of photography, from macro to wide-angle.
