The UWL-28M52 fisheye conversion lens has a magnification ratio of 0.41. This will give up to 168 degrees field of view (camera and housing dependent).
The UWL-28M52 is an advance on the very successful UWL-30 lens, having been redesigned for compatibility with compact cameras with 28mm (35mm camera equivalent) wide lenses.
Dry, inert gas is injected into the lens during manufacture. No humidity in the air space of the lens reduces any possibility of fogging to a minimum.
The UWL-30M52 has M52 thread and can be mounted directly on the FIX S95 , Fix S100 housings or Olympus housings equipped with the M52 thread. A step up ring is included to simplify mounting on housings with 67mm thread.
