Description
Maximum angle of view 100.5°underwater for ultra wide shot and 158.35°on land for fish-eye shot.
In addition to ultra wide angle of view, optical design of the UWL-100 allows closer focusing distance which benefits you when shooting wide macro image.
Optional “Dome Lens Unit II for UWL-100” further widen maximum angle of view to131.6°underwater for semi-fisheye imaging.
Optical construction is 5 elements in 4 groups with coated optical glasses including achromat lens (achromatic doublet) which effectively suppress optical aberrations and elicits master lens performance.
