AquaTech underwater equipment is never available for same-day pickup or for overnight shipping. It always needs at least a 2-day lead time for order preparation.
Special Note: This is not a dive housing. It is suitable for depths of only 33' for under 5 minutes or only 16.4' for over 5 minutes. It is best for surf, snorkel, and fashion shooting.
The AquaTech CZ Zoom Gear for Select Canon 16-35mm Lenses allows you to zoom your lens underwater with a port and housing. To use it, you will need to also rent an AquaTech P-110 Underwater Port, AquaTech PD-85 Underwater Port, or AquaTech P-120 Underwater Port. Zoom gears are not required for underwater protection but if you don't use one, and opt to just use the lens port alone, then you will have to choose your focal length ahead of time on your zoom lens and stick to it throughout your underwater session. See this AquaTech Housing and Lens Port Compatibility Chart to find out which zoom gears are compatible with which ports.
Warning: Not for the Canon 16-35mm f/2.8L III. For that lens, see the AquaTech CZ Zoom Gear V2 for Canon 24-70mm f/2.8L II and Canon 16-35mm f/2.8L III.
