Featuring a wide 120 degree field of view and a zero minimal focus distance, Fantasea's UWL-400F allows you 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. You can focus closer and fill the frame with smaller subjects.

The UWL-400F is designed for use with cameras with 24mm (or higher) lenses.

The lens mounts on 52mm threaded lens ports. The EyeDaptor M67-F52 lens adapter is included in the box and allows mounting the lens on housings featuring a 67mm threaded lens port. Adapters for other sizes are available.

While it can be added and taken off during a dive it's size and the fine threads on the port can make this awkward underwater. It is better to install it and shoot wide angle throughout the dive.
