Designed for 24-hour operation the Tamron 12VM412ASIR uses infrared corrected lens elements to produce brighter images in lighting conditions ranging from ambient to totally dark locations and is compatible with both Day/Night and conventional B/W cameras. Using special multi-layer lens coating, this vari-focal lens provides corner-to-corner image quality and compensates for glare and ghosting caused by back-lit environments.
