Product Information
The Fantasea BigEye Lens Kit M55 is a patented underwater wide angle lens that fits over a camera housing's lens port and can be installed or removed while still underwater, mid-dive. It threads onto 55mm or 67mm lens ports and carries a multi-layered anti-reflection coating on both sides to cut down on lens flare.
Who it is for
This lens suits underwater photographers and divers who want to shoot seascapes, other divers, shipwrecks, and schools of fish in a wider frame without having to back away from the subject. Staying closer to the subject means the shooter keeps the benefit of water clarity and any artificial light sources.
Key details
- Patented wide angle design that attaches over the housing lens port rather than inside it.
- Can be mounted and removed underwater during the same dive, letting a diver switch between standard and wide angle framing on the fly.
- Multi-layered anti-reflection coating applied to both sides of the lens, which significantly reduces lens flares.
Compatibility and sizing
The BigEye Lens Kit M55 is built to mount on 55mm or 67mm threaded lens ports, so it is intended for housings and ports that use one of those two thread sizes. Confirm your housing's port thread size before ordering to make sure the lens seats correctly.
