Using a different lens

The CS-mount of the camera allows you to use other lenses. The field of view (= covered area) of an 8mm lens is half of the field of view of the 4mm lens (see figure below).

Lenses available are: 4mm/F1.2 lens 8mm/F1.2 lens 4mm/F1.2 auto-iris lens 8mm/F1.2 auto-iris lens

The cameras are supplied either with the 4mm or 8mm lens.

The auto-iris lenses are recommended when the camera is used in environments with variable light conditions (eg. outdoors). By means of the auto-iris the amount of light going through the lens is regulated. The auto-iris is DC-controlled through a 4-pole connector at the back of the camera (3).
