2.8 - 12mm Varifocal Manual Lens
Varifocal lenses offer maximum flexibility in camera installations requiring a wide range of focal lengths. Focal length adjustments can be made with a turn of the dial, virtually eliminating the cost and inventory problems associated with improper monofocal lens selection. All lenses are CS-Mount, comprised of all glass optics and come with locking set screws and a durable metal barrel and mount.
Manual Iris Lenses are used primarily for indoor use with stable or moderately variable lighting conditions.
