Sea Frogs Extension Adapter Ring V.10 for 6" & 8" Dome Ports

Sea Frogs 90mm Bayonet Mount| 61mm Extension Ring

The Sea Frogs Extension Adapter Ring V.10 adds a 61mm (2.4'') extension for use with Sea Frogs 6" and 8" dome ports, making it compatible with wide-angle and ultra-wide-angle lenses. It features the 90mm (3.54'') bayonet mount and fits most Sea Frogs underwater housings, excluding the A6xxx and RX1xx series models. If you already own a Sea Frogs dome port, there's no need to purchase a new one to fit a different lens—simply swap the extension ring for a perfect setup.

Please note: Extension rings are not suitable for flat ports and cannot be stacked.
