This kit includes a dome port for the Ikelite TG-7 housing that replaces the standard flat port, and the OM System (formally Olympus) mini wide angle lens and lens adapter that connects directly to the camera. Using the dome alone will increase your angle of view a little and make the system great for over/under shot. When used with the FCON T-02 wide angle lens then your angle of view becomes super wide making it great for photographing really large subject.
