Ikelite 5516.16 DLM 6-inch Dome Port with Zoom Extended .375 Inch
An extended dome port providing zoom function for most mirrorless interchangeable zoom lenses when used with the appropriate zoom sleeve.
An optical-grade acrylic 6-inch diameter dome allows you to fully take advantage of the angle of view of your lens. Acrylic produces virtually identical image quality to glass yet is much lighter weight and easier to pack.
Ikelite’s unique zoom sleeves are simple and affordable. Zoom sleeves are particular to the lens for proper operation. Refer to the appropriate port for your housing to determine compatibility.
