  • The UWL-100 28AD 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 100°, above water view angle 179°). With the optional Dome Unit for UWL-100, an attachment dome to fit over the UWL-100 28AD, it is possible to achieve even wider underwater angle of view 150.8 degrees.
    Note: "Dome Spacer for UWL-100 28AD" part is necessary to attach Dome Lens Unit to lens.
  • In addition to enabling extreme wide angle of view, the optical design of the UWL-100 28AD allows closer focusing distances so better wide-macro (close focus wide angle) photography is possible.
  • The lens is constructed of high quality optical glass with multi-layer anti reflective coating on both sides. Four high quality optical glass lens elements are arranged in four groups. By design, the UWL-100 28AD minimizes aberration to achieve master lens performance.
