Computar TG3Z2910FCS 1/3-inch 2.9-8.2mm f1.0 Varifocal Lens

The Computar TG3Z2910FCS is a high‑performance varifocal lens designed for surveillance and CCTV applications using 1/3‑inch image sensors. With a focal length range of 2.9–8.2 mm, it allows flexible zooming from a wide field of view to a more focused view without repositioning the camera. The lens features a bright f/1.0 aperture, which enables excellent low‑light sensitivity and helps maintain image quality in dim conditions. It uses a DC auto‑iris mechanism to automatically adjust the aperture based on lighting, ensuring consistent exposure across varying brightness. Mounted on a durable CS‑mount metal barrel, the lens includes locking set screws for zoom, focus, and iris to lock in your desired settings firmly. The aspherical glass optics minimize distortion, delivering sharp, corner-to-corner clarity for reliable surveillance. Compact and robust, this lens is ideal for day/night CCTV systems that demand high image quality and adaptability.
