The Dome Lens Unit II for UWL-H100 is a dedicated super dome option for UWL-H100 series wide conversion lens to increase underwater view angle by simply attached it on the compatible wide conversion lens to provide "more wide angle image" and "more close-up image" comparing to sole use of the UWL-H100 series underwater.
*The "Dome Lens Unit" patented in the U.S.
Maximum angle of view underwater is [144.8°] with "UWL-H100 28LD" or "UWL-H100 28M67 Type1/Type2" wide conversion lens.
Unique optical design allows to shorten minimum focal distance with super wide view angle thus effective for ultra wide macro imaging and capturing clear image even in poor visibility condition.
The Dome Lens Unit II is made of optical glass with inner anti-reflection multi-coating to minimize flare and ghost in backlit condition.
