Aquatica Neoprene Light Blocking Mask for Fisheye Lenses

This Neoprene Light Blocking Mask from Aquatica is designed for use on fisheye lenses in Aquatica underwater housings. When the camera's built-in flash is used to trigger external strobes, this mask around the lens will block the light from the flash, thus preventing internal reflection off the front element of your dome lens port.
