Lens Olympus Wide 100 degrees 0.6x (67 mm)

The Olympus PTWC-01 is a high quality 100 degrees wide angle conversion lens.

The lens works on housings with ports that have a 67 mm thread in the front. The lens has a magnification of 0.6x. The large size of the lens blocks the camera's built-in flash so an external strobe should be used. 

The lens allows you to get closer to large subjects. This will improve your underwater photos by increasing contrast and color saturation.
