Frequently asked questions about gears for underwater housings
What is a gear for an underwater housing?

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.

You can use port charts to find the correct gear for your specific lens, port and underwater housing.
