In such cases, open the lens iris (refer to page 9) and adjust as follows.

1) Fixed focus lens

Set the lens focus ring to infinity and pickup a camera subject at least 20 meters distant. Loosen the lens mount setscrews (2 screws) and turn the lens and lens mount ring to adjust the focus. After adjusting, tighten the lens mount setscrews.

2)Varifocal and Zoom lens

1)Set the lens to maximum telephoto and pickup a camera subject at least 20 meters distant. Loosen the lens mount setscrews (2 screws) and turn the focus ring to adjust the focus while using care not to turn the lens and lens mount ring.

2)Set the lens to maximum wide angle and pickup the same camera subject. While using care not to turn the lens focus ring, turn the lens and lens mount ring to adjust the focus. Repeat these steps until focus is obtained at both telephoto and wide angle settings. After adjusting, tighten the lens mount setscrews.

※The flange back adjustment can adjust C~CS mount range.

※The angle of view is adjusted by turning the lens zoom ring.
