Happy New Year from all of us at aquatech!
AquaTech lens zoom designed to work with the Canon 17-40mm f/4.
Each AquaTech lens Port Zoom Gear is designed to work with a dedicated lens. The Zoom Gear will allow full zoom control on either the Delphin or Elite Water Housing and should operate in a smooth and responsive manner. This lightweight Zoom Gear is made from Delrin and will not lose shape over time and 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 fast changes are needed.
