Focus gears allow access to the manual function focus of a lens in an underwater housing. Use may require specific port extensions and may not be available for all housings and lenses.
This focus ring is designed specifically for Canon RF 100 mm f/2.8L Macro IS USM lenses in underwater housings by Isotta.
Made of lightweight but durable plastic to protect the lens from damage, and with two O-ring seals for a better grip. The gear rim is continuous.
