Computar Ganz HG3Z1014AFCS 1/2" 10-30mm f1.4 Varifocal CCTV Lens

CS-Mount Varifocal Lens for 1/2" Sensors

The Computar Ganz HG3Z1014AFCS is a varifocal CCTV lens designed for CS-mount cameras using 1/2" format sensors. It provides a 10-30mm focal length range with a 3x optical zoom for flexible field-of-view adjustment. The lens features an f/1.4 maximum aperture for low-light sensitivity and all-glass optics with an aspherical surface. It is built with a durable metal barrel and includes locking setscrews to secure focus and zoom positions.

Verify Camera Mount and Sensor Format

Before ordering, confirm that your camera uses a CS-mount interface and is equipped with a 1/2" image sensor. The lens requires a video auto-iris drive with amplifier support from the camera body for automatic aperture control. Ensure the installation allows for a minimum focus distance of .6 metres for close-up detail. The manual zoom ring must be accessible at the mounting location for focal length changes.

IR Correction and Auto Iris Simplify Day/Night Use

The IR-corrected optics eliminate focus shift when the camera switches between visible and infrared illumination, removing the need for manual refocusing at night. The integrated video auto-iris amplifier automatically adjusts the aperture from f/1.4 to 360C to maintain consistent exposure across changing light conditions. These features reduce ongoing maintenance and ensure reliable image capture in mixed lighting environments without additional external filters or controllers.
