Tamron 13VM308ASIRII CS-Mount, 3-8mm Varifocal Fixed Manual Iris Lens

Deliver flexible, high-quality surveillance coverage with the Tamron 13VM308ASIRII CS-mount varifocal lens — designed for security and monitoring applications that require clear, reliable imaging. This Tamron varifocal lens offers a 3–8mm focal range (2.7x optical zoom) and a bright f/1 maximum aperture to capture usable footage in low-light environments without excessive amplification. With a field of view spanning roughly 26.8° to 92.5°, installers can quickly adjust framing for corridor, doorway or wide-area views while the manual iris with lock maintains consistent exposure as lighting fluctuates. Optimized for modern digital camera sensors, the lens reduces color smear and preserves edge-to-edge resolution, improving identification and forensic value of recorded video. The compact CS-mount form factor speeds deployment across CCTV, IP surveillance and monitoring systems. Ideal for security integrators and facilities managers who need dependable, high-performance optics — add the Tamron 13VM308ASIRII to your next surveillance upgrade or contact us to spec it into your project.
