Back Focus Adjustment
The back focus adjustment is located at the front of the camera and is accessible from either the top or
bottom of the case.
To adjust the back focus:
1.
Loosen the two back focus mechanism locking screws (top and bottom of the camera).
2.
Turn the back focus ring anti-clockwise (when viewing the front of the camera) until the CMOS
sensor assembly is as far away from the back of the lens as possible.
3.
Turn the back focus ring clockwise until focus is achieved.
4.
When the back focus adjustment is satisfactory, tighten the locking screws. Do not over-turn or
force the back focus adjustment ring.
Note:
Always turn the back focus ring such that during focusing, the CMOS sensor assembly is
brought towards the back of the lens (i.e. clockwise). If the point of best-focus is passed, repeat
the back focus procedure from step 2.
