AquaTech PD-65 DomeLens Port

Designed for select Canon, Nikon, Sigma, and Tokina wide-angle lenses. See the list below for specific compatible models.. It is depth rated to 33' but is really meant for very shallow water and surface use, and should not be used at depths greater than 15' for longer than a few minutes at a time. The dome's 6" diameter makes it effective for over/under shots where half the lens is above the water's surface and the other half is below. By correcting for the underwater size distortion that causes everything to look larger and closer, the dome restores a wide angle of view to let you fit more in frame.

The port's replaceable front element is made of molded acrylic, and it also features an aluminum body and a screw-on mount. Additionally, it is mechanically sealed without the use of adhesives.
