Engineered for challenging, dynamic lighting conditions, the lens incorporates a responsive DC auto-iris to maintain optimal sensor exposure, alongside full infrared (IR) correction to eliminate focus shifts during day-to-night transitions. It features manual zoom and focus controls, supports a large 1/1.8" maximum image format sensor, and is built with a standard CS-mount system to ensure a highly reliable and professional deployment.
