Computar 12.5-50 mm F1.4 DC-Iris CS-Mount Lens, 5800-791

Computar 12.5-50 mm F1.4 DC-Iris CS-Mount Lens

The Computar 12.5-50 mm DC-Iris lens is a varifocal telephoto CS-mount lens that lets compatible AXIS box cameras read distant scenes, with an iris that adjusts automatically as light changes. Axis recommends DC-iris optics where light levels vary, and the lens is IR-corrected, so focus does not need re-adjusting when the camera switches between day and night mode. It covers sensors up to 1/2.7-inch and narrows the horizontal view to roughly 7 degrees at full zoom on the AXIS M1135 and M1137 families.
