Ikelite Modular 8" Dome Port with 5.1" Lens Extension Kit includes our Modular Lens Extension for lenses up to 5.1 inches (12.9 cm) in length (product number 5510.28). The Lens Extension threads onto the base of the Modular 8-inch Dome for simple assembly.

Lens Extensions are available in a variety of lengths to accommodate most popular wide angle and zoom lenses. Additional extensions can be purchased separately and used with this Modular 8-inch Dome. A Modular Glass Flat Front can be added in place of the 8-inch Dome to use the Lens Extension with compact macro lenses.
