The UWL-H100 was specifically designed for compact digital cameras with a 28mm equivalent wide angle lens. The maximum view angle is 100.8º underwater and 179º on land for fish-eye imaging.
The optional INON Dome Lens Unit II for UWL-H100 # 64311 increases the maximum viewing angle to 144.8º underwater for ultra-wide angle semi-fisheye imaging.
The lens is constructed of 4 highly refractive optical elements in 4 groups with coated glass to effectively suppress optical aberrations and improve lens performance.
The aluminum 67mm threaded ring attaches directly to housings and adapters featuring a 67mm thread.
Angle of coverage will vary depending on focal length of the camera and distance from the front of the camera to the back of the UWL-H100 lens. Some vignetting (dark shadows around the edges of the image) may be present. Vignetting may be reduced or eliminated by zooming in slightly and/or cropping the image in post production.
