The UWL-105AD is a wide angle conversion lens with 105 degree maximum view angle.

It is designed for smaller cameras with smaller lens diameter. Instead of a threaded mounting system, Inon “AD” series lenses have an “AD” bayonet mount for quick and secure “one touch” underwater attachment or removal.

The UWL-105AD can be mounted to camera housings with an Inon AD Mount Base, sold separately. There are many AD Mount Bases available for specific housing models.

• The UWL-105 AD is designed to perform equally well both underwater and above. Underwater it is an extreme wide-angle converter, in air it is a fisheye converter. (Underwater view angle 105.6°, above water view angle 179.0°, when used with S40/S30 +WP-DC300)
• In addition to enabling extreme wide angle of view, the optical design of the UWL-105AD allows closer focusing distance so better “wide-macro” (close focus wide angle) photography is possible. (When used with the S40/S30 +WP-DC300, in Standard Mode the focus range is Infinity -18.9cm compared to camera only focus range of Infinity - 80cm. In Macro Mode the focus range is 18.9cm - 0.4cm, compared to the camera only range of 80cm - 10cm)
• The lens is constructed of high quality optical glass with multi-layer anti reflective coating on both sides. Four lens elements arranged in four groups correct for chromatic and spherical aberration. By design, the UWL-105AD minimizes aberration to achieve master lens performance.
• Quick, secure “one touch” lens attachment and release with Inon’s AD Standard bayonet mount.
