Increase the length of your Aquatica underwater housing's port to allow for the use of longer lenses or teleconverters via this Port Extension Ring that measures 3.8" in length. The ring is also designed to enable positioning of the front element of your lens as close as possible to the interior of the port, in order to minimize distortion for better image quality. See the Dimensions Chart to learn how to measure properly for an extension ring.
A stainless steel locking mechanism ensures a secure connection between the ring and the lens port, while your camera housing's own locking mechanism connects the ring securely to the housing. The extension ring is crafted from a 6061 T6 aluminum alloy, which has been anodized for excellent resistance to corrosion. It features a depth rating of 295'.
