Enjoy all the versatility of your Canon 24-70mm f/4L IS USM Lens underwater by using
Ikelite's Zoom Sleeve with their compatible dome or flat lens port. This small but crucial accessory will allow you to zoom in and out with the 24-70 when the port is attached to an Ikelite DSLR camera housing. See the
Port Finder,
DSLR Port Chart, 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.
