Nauticam Bayonet Mount Systems – A Smarter Way to Swap Wet Lenses

If you’ve ever tried switching lenses underwater while juggling a camera, strobe arms, and surge—then you already know the value of a quick, no-fuss system. These Bayonet Mount Systems by Nauticam are one of those tools that just makes sense. They let you swap between wide-angle and macro wet lenses in seconds, with no threading,fumbling, or unnecessary stress.

These mounts and holders are made to fit securely on your housing, float arms, or even directly to the port. Their locking mechanisms are firm and confident—once it clicks, it stays. Whether you're carrying a WWL-1 for coral photography or an EMWL for macro critters, being able to switch lenses on the fast decreases chance of missing a good shot just because the gear’s in the way.

Most options in this category are compact and travel-friendly, built from anodized aluminum and durable marine-grade materials. You’ll find single and double holders for your arms, plus adapters that convert standard M67 or M77 threads into the bayonet system. And if you’re shooting something like the EMWL, there are dedicated mounts designed to balance and protect that setup too.

In short: this is one of those upgrades that feels small—until you use it. Then you wonder how you ever dove without it.

Worth Having Nearby

• Lens holders: Great for parking your second lens on an arm while shooting with the other.
• Thread converters: If your wet lenses are threaded, these let you step into the bayonet system without buying everything new.
• Float arms: Some larger lenses need buoyancy balance. Float arms with built-in holders are a smart double-duty option.
