The DC powered auto iris sytem feeds power from the camera to the lens iris via dedicated cable.

  • Auto Iris Feature

The Fujinon YF4A-SA2LB uses a DC powered auto iris system that takes power from the camera. The lens itself measures the lighting conditions and sets aperture. There is a special cable and connector on the lens for this purpose. This model lens comes with a 9 inch cable to fit cameras with connectors in unconventional positions.

  • Wide Range of Lighting Conditions

The lens is capable of adapting to very bright and very low lighting situations. Its maximum aperture is a fast 2.0 so it can be used dimmly lit environments. When confronted with extremely bright scenes the lens has a built-in ND filter that can effectively stop the lens down to a maximum of f/360.
