Great quality glass port for the 9-18mm wide-angle lens for Olympus brand housings. Also works with the 14-42mm II lens!

Why is this dome great? There is a 25% increase in FOV over the standard Olympus flat port and it retains the in-air field of view of the Olympus M.ZUIKO DIGITAL ED 9–18mm f/4–f/5.6 lens and M.ZUIKO DIGITAL ED 14–42mm f/3.5–f/5.6L lenses.
