The Computar i-CS 2.8-8.5 mm lens is a wide-to-standard varifocal CS-mount lens with three motors for remote zoom, focus and iris control on AXIS box cameras. It follows the i-CS standard, so the camera can adjust the lens automatically or from a distance, with no ladder trips after installation. The lens is IR-corrected and, per the Axis datasheet, supports a 1/2.7-inch sensor. Axis product data lists it as the standard lens for the AXIS Q1615 Mk II.
