Back-focus
Adjustment
Although the camera lens was back-focused by the
manufacturer prior to shipping, it may be necessary to
make modifications.
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 could change
slightly if the camera iris is adjusted when focused on
a light scene, which then changes to a dark scene.
However, the camera will remain in focus if the
camera iris is adjusted when focused on a dark scene,
which then changes to a lighter scene.
To make back-focus adjustments, perform the
following steps:
1. After mounting the lens on the camera, apply
power.
2. Open the camera iris by turning the lens level
control counterclockwise.
