Wide angle photography allows you to get close to your subject without losing part of the subject. This makes it great for photographing wrecks, large animals and people. This Ikelite Dome Port is recommended for wide angle lenses from 17mm to 28mm, and short zoom lenses. Zoom lenses require a +4 Diopter close-up lens available from camera stores. Wide angle lenses will focus at 12" (30.5cm) and do not require the addition of any close-up lens when used in a dome port.
The Ikelite acrylic dome is injection molded specifically for underwater photography, and represents the finest optics in the industry. Port is equipped with an external dome shade impact ring for proper lighting and protection of the port element. Port is 4.6" (11.7cm) in length and is designed for lenses that are 4.5" (11.4cm) in length or less. The Port comes with an instruction guide and is covered by a 12 month limited warranty.
Maximum lens diameter is limited to 3.3" (8.4cm). The diameter for attachment of zoom or focus clamps is limited to 2.8" (7.1cm). Lens length is measured as the maximum extended length from attachment point on the camera body. Only lenses with rotating barrel control for zoom can be used. Push-pull zoom control cannot be operated.
This product has a limited warranty of 12 months.
