Which port connector, extension ring or lens rings do I need?
Most Isotta housings offer interchangeable port connectors that allow the use of a variety of lenses. However, different lenses may require different ports and extension rings to preserve or optimise underwater optics. Some lenses allow access to zoom and manual focus functions in the housing via a gear set that works in conjunction with the housing or extension ring. Refer to the appropriate table for your housing system..
