The back focus adjustment is located at the front of the camera and is accessible from either side of 
the case.

To adjust the back focus:

1. Loosen the two back focus locking screws (one on each side).

2. Turn the back focus ring until the object is in focus.

3. When the back focus adjustment is satisfactory, tighten the locking screws. Do not overtighten the 

locking screw or force the back focus adjustment ring.
