AOI UWL-400A M52 0.50x Underwater Wide-Angle Wet Lens

The AOI UWL-400A Wide Angle Lens is a Super Sharp Wide Angle conversion lens that attaches to the housing lens port thread and can be installed and removed during the dive. The lens is compatible with the AOI Bayonet System.

The AOI UWL-400A was designed for cameras featuring a 24mm lens (35mm equiv.) or any higher focal range. 
It is perfect for photographing seascapes, divers, ship wrecks and schools of fish without moving further away from the subject, thereby still taking full advantage of water clarity and artificial lighting. 

It also allows focusing on short distances, making it perfect for CFWA (Close Focus Wide Angle) photography. 

The AOI UWL-400A is compact and lightweight, allowing for easy storage and transportation and comfortable handling of the lens during the dive.

Compatibility:

The UWL-400A is compatible with most all cameras featuring a 24mm lens (or a higher focal range). It can also be used with some cameras featuring a wider lens by zooming in to avoid a vignette. 

The UWL-400A features a 52mm thread and can be mounted directly on lens ports with a 52mm thread or on lens ports featuring a different thread, by using a compatible adaptor. 
Alternatively, the 52mm threaded adaptor mount screwed into the lens can be replaced with a Bayonet mount (separately purchased) for quick and easy installation and removal of the lens when used with a compatible Bayonet adapter.
