The Fantasea UWL-400Q Wide Angle Lens (also known as AOI UWL-400A) 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 Fantasea Bayonet System (QRS). Bayonet adaptors can be separately ordered.
The UWL-400Q 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 UWL-400Q is compact and lightweight, allowing for easy storage and transportation and comfortable handling of the lens during the dive. Compatibility
The UWL-400Q 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-400Q 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. The EyeDaptor M67-F52 lens adaptor is included in the box and allows mounting the lens on housings featuring a 67mm threaded lens port. 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 system (QRS).
The Wide Angle Dome Lens will increase the field of view by 100%
This lens is made by quality lens manufacturer AOI - the 400A version of this lens is the same as the AOI UWL-400 with the only difference that the 52mm thread can be removed and replaced with the quick release system mount from AOI / Fantasea and then mounted on a 52mm port using the AOI Quick Release Mount Base
