The Dome Lens Unit functions as a semi-fisheye converter when attached to an Inon UWL-100 Achromat Type 1 or Type 2 lens. The Dome Lens Unit enables the UWL-100 underwater angle of view to increase close to that of UWL-100 when used in air.
While the special optical design enables wider angle of view, the Dome Lens Unit also allows closer focusing distances for better close focus wide-angle imaging. (Focus Range: infinity - 1.9cm when using C-3030 Zoom with Macro Mode on "6").
When attached on an UWL-100 28AD wide conversion lens with a "Dome Spacer for UWL-28AD" part,($18.95) the Dome Lens Unit functions as a fisheye converter, enabling 150.8 degree underwater view angle, approaching the 179.0 degrees of the UWL-100 28AD when used in air.
The Dome Lens Unit is specially designed for optimum performance with the UWL-100 lens series and is made of optical glass with an inside anti-reflection multi-coat. Optimum design and the highest quality optics, together with the one-piece integral shade/protector, minimize flare and ghosting for clearer images. |
