The Axis Communications Varifocal DC Iris Lens (15 to 50mm) from Fujinon has a compact and lightweight design. This lens uses a low-dispersion glass with a high-reflective index and Fujinon's Aspherical Technology (AT) for maximizing optical performance. It offers sharper, excellent quality images, and higher optical performance.

The lens features a fast aperture and is equipped with built-in ND (Neutral Density) filters for use with light sensitive cameras, plus metal CS mounts with locking screws and DC-iris system. The focal length is 15 to 50mm and the lens fast aperture (F-number) is 1.5.

The Fujinon varifocal Lens 15 to 50mm DC-iris is recommended for use with the Axis fixed network cameras. The lens is day/night corrected and therefore no adjustments will be needed when the camera's IR-cut filter disengages.
