The Aqua Tech LP-2 Dome Port for Canon 8-15mm f/4 Lens - 6" is a dome lens port compatible with all current AquaTech Sport Housings, as of October 2011. Designed for the Canon 8-15mm f/4 lens, this dome is great for surface photography and use in turbulent water situations. No tools are required to attach or remove the port from the housing.
The port is made of optically-correct molded acrylic and is machined from an 8" hemisphere, in order to allow for a low-profile dome. It's mechanically sealed without the use of adhesives, and there is a piston seal O-ring on the major thread base to keep a watertight seal. The dome element is replaceable.
