CS-mount varifocal lens for 1/3" sensors

The Computar Ganz TG5Z8513AFCS-IR is a CS-mount varifocal lens built for analogue CCTV cameras using a 1/3" format sensor. It provides a 5x optical zoom range from 8.5-40mm, allowing installers to adjust the field of view without relocating the camera. Manual zoom and focus rings with locking setscrews secure the chosen setting. The all-glass optics and metal barrel are designed for fixed surveillance positions.

Video auto iris with IR correction

The lens features a video auto iris drive with an integrated amplifier that automatically controls the aperture from f/1.3 to 360. This maintains consistent exposure across changing light levels without manual intervention. IR-corrected optics eliminate focus shift when the camera switches between day and night modes, keeping the image sharp under infrared illumination. Focus operates from 0.8 m to infinity.

Locking setscrews and three-year coverage

Locking setscrews on the zoom and focus rings prevent vibration from shifting the adjusted focal point after installation. The durable metal barrel and mount resist wear in continuous operation. A three-year manufacturer warranty covers defects in materials and workmanship. No additional software or accessories are included in the package.
