The iris has been adjusted to close to aproxymately F8.

If it is required to change this then carry out the following:

Remove the lens cover, first removing three screws.

Slacken two screws holding actuator and adjust by sliding actuator in the correct direction.

Tighten screws and reassemble.

Operation of Kangaroo iris lens.

Under most conditions the lens iris is fully open.

The exposure is controlled by camera shutter speed.

When the scene illumination is to hight for the camera, at the shortest shutter speed available, the lens iris is caused to close to a predetermind aperture typicaly around F5.6 to F8.

The adventage of using a Kangaroo rather then an auto iris lens is that since shutter speed is always as short as possible. Good "stills" of moving objects such as car number plates can be made. The system works best with a camera designed specifically for use with a Kangaroolens.

It is possible to control lens using a light sensor but it would be difficult to adjust the lightlevel at wich the changeover is made.
