Field-of-View Formulas:
Horizontal view = (.87 x a)/b
Vertical view = (.634 x a)/b
where a = distance from camera in meters or feet
where b = zoom power (such as 12X)
Example of a wide angle view with zoom power of 12X
at 18 m from the camera:
(.87 x 18)/12 = 1.2m or 4ft.
(.634 x 18)/12 = .95m or 3ft.
