For best results, perform back focus adjustments at night or while using a #6

or #8 welder's glass in front of the lens. The focus of the camera will

change slightly if the camera iris was adjusted on a light scene, then

changes to a dark scene. However, the camera will remain in focus if the

iris was focused on a dark scene and the scene lightens.

1. The lens should be mounted on the camera before applying power.

2. If a picture is visible, focus on the picture. If the picture is not visible,

open the iris on the lens. Open the lens as wide as possible by placing

the welder's glass in front of the lens and forcing the lens to automatically

open.

3. When the iris is open to the widest point, re-adjust the focus for clear

picture. If a clear picture is not possible, set the focus ring to midrange.

4. Loosen the back focus lock screw.

5. Adjust the back focus ring for a clear picture.

6. Tighten the back focus lock screw.

7. Fine tune the focus with the focus ring on the lens.

8. Remove the welder's glass from in front of the lens.

9. Adjust the iris of the lens for the best picture quality.
