Product introduction:

   Perspective 
   mastering the lens angle of taking scenery is important. 

   the angle of view varies with the focal length of the lens and the size of the camera CCD. Focus


   the focal length of the lens is measured in millimeters, which is causal to the viewing angle obtained by the lens. The small focal length lens has a large viewing angle, while the long focal length lens has a telescopic effect and a narrow viewing angle. The focal length of the covered scenery can be calculated by the following formula: 
 f = V xD / V. (1) f = h xD / H. (2) 


   f: lens focal length

  v: vertical dimensions of the scene; V @   nbsp; nbsp H: Size of landscape 
  D The distance between the lens and the scene is 
  v: vertical dimensions of the CCD (see table below) 
@h: horizontal dimensions of the CCD (see table below)
