1/2" 30-120mm Auto Iris Zoom Lens CS-Mount 5MP for Security Surveillance Camera

High-Performance CS-Mount Zoom Lens for 1/2″ 5 MP CMOS Sensors

This precision-engineered lens features a 30–120 mm focal length range (4× optical zoom), an F1.6 maximum aperture with DC-driven automatic iris control, and full 5 megapixel (5 MP) optical resolution across the entire focal range. Designed specifically for integration with 1/2″ format 5 MP CMOS image sensors, it delivers consistent edge-to-edge sharpness, minimal chromatic aberration, uniform illumination distribution, and negligible vignetting. The lens employs a robust metal housing and CS-mount interface to ensure mechanical stability, resistance to vibration and thermal drift, and long-term operational reliability in demanding environments. Manual focus and manual zoom mechanisms provide precise optical alignment, while the optimized image circle fully covers the 1/2″ sensor format—eliminating corner darkening and maximizing sensor utilization.
