With Nimar's dedicated 5" Optical Glass Dome Port for the Sigma 10-20mm f/3.5 EX DC Lens, you can capture detailed shots of coral, moray eels, blue-ringed octopi, and other wonders of the sea at depths as great as 197'. The port features a bayonet mount for connection to Nimar's Water Sport Housings for Canon DSLR cameras, as well as a gear for manual zoom control with your lens.

The clear, dome-shaped front element magnifies images to a lesser degree than a flat port does, and corrects for the underwater size distortion that makes everything appear 25% larger and closer--thereby helping to restore the 10-20mm's wide angle of view. The front element is crafted from crystal optical glass for a high degree of clarity, while the body is made from durable, black Delrin acetyl resin.
