Tamron 13VG308ASIRII CS-Mount 3-8mm Varifocal Fixed DC Auto Iris Lens

Optimize your CCTV and security monitoring with the Tamron 13VG308ASIRII varifocal lens — engineered for reliable, flexible surveillance without the hassle. This Tamron varifocal lens (3–8mm) lets integrators and security teams quickly adjust field of view on-site to capture wider scenes or zoom into key areas without moving the camera. With a bright f/1 maximum aperture and DC auto-iris, the lens maintains exposure across changing light conditions and supports low-light performance for round-the-clock monitoring. The IR-corrected day/night design eliminates focus shift and IR bleed when using infrared illumination, making it ideal for night surveillance. Built for 1/3" sensor CS-mount cameras, the lens provides a 26.5°–92.5° field of view and uses aspherical/SD glass and multi-coatings to minimize flare, ghosting, and chromatic aberration—delivering sharp, actionable video for security and forensic review. Independent locking rings and a slip-mount mechanism simplify installation and secure settings after deployment. Perfect for retail, parking, perimeter, and facility surveillance—add this Tamron varifocal lens to your CCTV toolkit for dependable, high-quality monitoring.
