CCTV lens for 1/3" CS-mount cameras

The Computar Ganz TG2Z1816AFCS is a varifocal video auto iris lens built for CS-mount cameras with 1/3" format sensors. It uses all-glass optics in a durable metal barrel and includes locking setscrews to secure zoom and focus positions. The lens suits surveillance installations that need adjustable coverage without moving the camera.

Focal range and aperture

The lens covers a 1.8-3.6mm focal length with a maximum aperture of f/1.6 and a minimum of 360C, providing a 2x zoom ratio. It delivers diagonal viewing angles from 99° to 173.8°, horizontal angles from 79.4° to 144.2°, and vertical angles from 59.6° to 109.4°. Minimum focus distance is .2 m with manual adjustment.

Video auto iris with amplifier

The integrated video drive with amplifier enables automatic iris control so exposure adapts to changing light levels without manual intervention. This removes the need to readjust the aperture when scenes shift from bright to low light. Buyers who need DC-drive auto iris or manual iris only will find this lens incompatible.
