The Pentax DC Auto Iris Vari-focal Lens (1.3 Megapixel) is a CS-mount lens with a focal length range of 2.6 to 8mm. The consistent focus technology in the Vari-focal Plus lens maintains clear focus across the entire zooming range without the need for refocusing with focal length or zoom range variation. Even when the focal length of the lens changes while tracking an object, the lens maintains a clear focus throughout. A unique focus and zoom interlocking mechanism prevents defocusing due to the independent movements of the focus and zoom lens groups while zooming. The iris ranges from f/1.3 to f/1.8 and the viewing angle (H) from 104.4 to 35.5°.
