With this 2.5" Lens Port Extension Ring, you can increase the length of your Aquatica underwater DSLR housing's port to enable the use of longer lenses or teleconverters. The ring features a manual focus knob, which is compatible with a required focus gear. Please consult your housing's port chart to find the right gear.
In addition to adding length, the ring is designed to allow for 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 reliable connection between the ring and the port, while your camera housing's own lock 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'.
