Product Information
The Fantasea UWL-400Q Wide Angle Lens is a 0.50X wide angle conversion lens. It attaches to the housing lens port thread, can be installed and removed during the dive, and is compatible with the Fantasea Bayonet System (QRS). It is designed for cameras featuring a 24mm lens (35mm equivalent) or a higher focal range, delivers a 120 degree diagonal angle of view, 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 without needing to move further from the subject, which keeps the benefit of water clarity and artificial lighting. A focus distance of 0mm from the dome also makes it suited to CFWA (Close Focus Wide Angle) photography. It works with most cameras that feature a 24mm lens or a higher focal range, and can be used with some wider lens cameras by zooming in to avoid vignetting.
