Product Information
The Fantasea Bayonet Female on Arm MB2 is a lens holder with a female Bayonet that attaches to Flat UL-TYPE 1'' ball arms, letting divers securely store accessory wet lenses when they are not mounted on the housing. It is built from hard anodized aluminum, weighs 122.5 g (4.3 oz), and lets a diver install or remove a wet lens with a simple 1/4 turn.
Who it is for
This lens holder is for underwater photographers and videographers who use wet lenses with Fantasea's Bayonet Mounting System and need a dedicated, secure place on their rig to stow a lens when it is not in use. It mounts directly onto a Flat UL-TYPE 1'' ball arm, so it fits existing UL-TYPE arm setups.

Frequently Asked Questions
What arms does the Fantasea MB2 lens holder fit?
The MB2 mounts on Flat UL-TYPE 1'' ball arms, so a wet lens with a compatible male bayonet can be stowed on the rig when not in use.
Can I store two wet lenses with one MB2 setup?
Yes. Two MB2 lens holders can be mounted opposite each other on the same Flat UL-TYPE 1'' ball arm, which lets a diver secure two wet lenses on a single arm when both are not mounted on the camera housing.
Does the MB2 work with any wet lens?
The MB2 has a female Bayonet fitting, so it only works with a wet lens that already has a compatible male bayonet installed. Without a matching male bayonet on the lens, the female Bayonet on the MB2 cannot engage with it.
What tools come with the Fantasea MB2?
The MB2 ships with the lens holder itself along with a screw and an Allen key, which are the hardware needed to mount the unit onto a Flat UL-TYPE 1'' ball arm.
