AquaTech lens zoom designed to work with the Nikon 24-70mm f/2.8 E ED VR.

Each AquaTech lens Port Zoom Gear is designed to work with a dedicated lens. The Zoom Gear will allow full zoom control on any AquaTech Water Housing and should operate in a smooth and responsive manner. This lightweight Zoom Gear is made from Delrin and will not lose its shape over time or with use. The Zoom Gear pitch is matched perfectly to the Zoom Control on the Water Housing to fast, responsive control in those critical situations when quick changes are needed.
