Product Information
The Fantasea UWL-400F Wide Angle Lens is a wet-mountable wide angle conversion lens that attaches to a camera housing's lens port thread and can be installed or removed underwater during a dive. It is built for cameras with a 24mm lens (35mm equivalent) or any higher focal range, delivers a 120-degree angle of view with 0.50X magnification, and is depth rated to 100 meters (330 feet).
Who it is for
This lens suits underwater photographers shooting seascapes, divers, shipwrecks and schools of fish who want to stay close to the subject while still taking advantage of water clarity and artificial lighting. Its 0mm focus distance from the dome also makes it suited to Close Focus Wide Angle (CFWA) photography, letting the shooter focus on subjects at very short range.
