The lens is a very important component of your camera. It regulates the incidence of light on the camera's CCD and thus ensures an optimal exposure of your pictures. All lenses have a standard mounting thread. You can easily mount CS-Mount lenses on any camera. The aspheric lenses ensure especially high-quality pictures and prevent poor focusing at the edges. The incidence of light through the iris is controlled by the camera's auto-iris function. The lens is connected to the camera with a DC plug. The distinctive features of this lenses are a different viewing angle and a different focal length. (The greater the focal length, the narrower the viewing angle and the nearer you can zoom in on the image.)
