The Fantasea-AOI UWL-09Pro is the finest and most professional wet wide angle conversion lens available. Featuring a quality optical glass dome and offering the most impressive optic specifications, the UWL-09Pro delivers stunning results that have no competition. The UWL-09Pro wet wide angle lens provides an exceptionally wide field of view and a zero minimal focus distance, allowing to shoot breathtaking wide angle and close focus images that are super sharp corner-to-corner and great on the details. It is perfect for a wide variety of compositions, including seascape, divers, ship wrecks and schools of fish, without moving further away from the subject, thereby still taking full advantage of water clarity and artificial light sources. The lens mounts on the housing lens port and can be installed and removed during the course of the dive. It can be mounted on 67mm threaded lens ports and other dimensions by using an adaptor.
