Aspherical Vari-Focal Lens
The 1/3" 2.8 - 12 mm F/1.4 vari-focal lens from Tamron can be used in nearly all CCTV applications. Among its key features, the lens offers aspherical optical technology, fast F/1.4 aperture, and locking mechanisms on the zoom, iris and focus rings. The aspherical element enhances performance by eliminating image distortion and providing corner-to-corner sharpness. The lens is 2.2" long and the diameter is 1.57". The lens is well suited for use in applications where wind or vibration is a factor in selecting equipment to install.
