Ikelite Zoom Sleeve for Canon EF 11-24mm f/4L or 16-35mm f/2.8L III Lens in Port

Enjoy all the versatility of your wide-angle zoom lens underwater by using Ikelite's Zoom Sleeve with their compatible dome or flat lens port. When the port is attached to an Ikelite DSLR or mirrorless housing with a Dry Lock Mount, this sleeve allows you to adjust the focal length of your Canon EF 11-24mm f/4L USM or 16-35mm f/2.8L III USM lens. See the Port Finder and DL Port Chart for complete compatibility information. The sleeve mounts onto the zoom ring of the lens and features teeth that mesh with the housing's zoom gear.
