Frequently asked questions about gears for underwater housings
What is a gear for an underwater housing?
A gear is a ring placed around a lens that allows you to control focus or zoom through the external controls of an underwater housing.
Do I need a gear for every lens?
Not always. Some lenses can be used without a gear, but for manual focus or zoom control, a compatible gear is required.
What is the difference between a focus gear and a zoom gear?
A focus gear is used to manually adjust focus, while a zoom gear allows you to change focal length on zoom lenses.
How do I know which gear I need for my underwater housing?
You can use port charts to find the correct gear for your specific lens, port and underwater housing.
Are gears brand specific?
Yes, gears are designed for specific lenses and underwater housing systems. Always check compatibility before choosing a gear.
