Product Information
The Fantasea FML Port Extension 25 is a hard anodized aluminum alloy spacer that adds 25mm of length to a lens port on housings and lens ports built on the Fantasea FML port system, and it is depth rated to 60 meters (200 feet).
Who it is for
This port extension is for underwater photographers and videographers using a Fantasea housing or lens port on the FML system who need extra length to accommodate a longer lens or a specific port configuration. Because multiple Port Extensions can be stacked one upon the other, it also suits divers who need more than 25mm of additional reach and want to combine two or more extensions to reach the exact length their setup requires.
