Iris
The light incidence is regulated in lenses using the iris and the iris setting.
To be able to optimally regulate the light, the lenses from computar offer
three possibilities of setting the iris. Depending on the field of applica-
tion, you can choose a manual setting or automatic control electronics
optionally in the lens (video) or in the camera (DC). Whereas automatic
iris control should be used outdoors owing to the unavoidable fluctua-
tions in lighting, lenses with a manual iris are only suitable for areas with
constant light conditions.
