Most underwater camera housings for interchangeable lens Mirrorless and DSLR cameras offer interchangeable ports that allow for the use of a variety of lenses. However, different lenses may require different ports and extensions rings to maintain or correct for underwater optics.

Some lenses allow for access to zoom and manual focus functions when inside the housing via a gear set that works in conjunction with a supported housing or extension ring. Consult the appropriate chart for your housing system. If a lens is not listed, it does not necessarily mean it will not work.

Here's a list of links to manufacturers' charts showing the available combination of ports, extensions and gears necessary to use various cameras and housings with supported lenses.
