INON UWL-105AD Coverage Chart
 Camera zoom setting
= maximum wide.
Angle of coverage
refers to format diagonal with main camera lens focused at infinity.
Coverage UW is given by the formula: L'
= 2 Arctan[ 43.266615 / (2 m f35e) ]
where f35e = 35mm equiv. focal length
of the camera lens in mm, and magnification m = 0.51.
Hence: L' = 2 Arctan( 42.4183 / f35e )
Note: 35mm equiv. focal lengths given in product literature are
usually approximations. |

Vignetting may
occur when camera 35mm equivalent focal length is less than 32mm.
Zoom in slightly to cure this problem.
