    18456 Port Extension Ring for Aquatica Bayonet Style Housings is rated 5.0 out of 5 by 4.
    Rated 5 out of 5 by from solid construction, crisp photos This metal ring spaces the dome port the correct distance from your lens to allow for the sharpest image. I used this with the Aquatica 9.25 inch dome and a Tokina 10-17mm FE zoom lens. The corner sharpness of my photos was noticeably improved with the extension ring.

    Rated 5 out of 5 by from Improved Design Required to replace much older 18456 for use with Aquatica Glass Dome Ports. Glass ports do not have removable shades so indexing on port lugs was off on older extension rings for shade to align with housing properly

    Rated 5 out of 5 by from Good product, but expensive ! This product is necessary to AT2i Aquatica housing with Mini Dome 4' and Tokina 10-17mm lens.
