Nauticam C1018-Z Zoom Gear for Canon EF-S 10-18mm [19549]

The Nauticam C1018-Z Zoom Gear 19549 is made for the Canon EF-S 10-18mm f/4.5-5.6 IS STM lens used in underwater photography and video configurations.  The gear enables access to the mechanical zoom function of the lens through the housing control system. This allows focal length adjustment while the camera remains sealed inside the housing. Use of the zoom gear may require additional port extensions or adapters depending on the selected housing and port setup.

Check the relevant port chart before installation. The C1018-Z Zoom Gear is intended specifically for the Canon EF-S 10-18mm f/4.5-5.6 IS STM lens.
