The lens is a very important component of your camera. Here you regulate the incidence of light on the camera's CCD and thus ensure 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 manually. (The greater the focal length, the narrower the viewing angle and the nearer you can zoom in on the image.)
