Flange Back Adjustment
The flange back is the distance between the lens (sold separately) and the image capturing surface of the camera. It is adjusted at the time of shipment from the factory to accommodate the types of lenses that are generally assumed to be in use.
Accordingly, the flange back does not normally need to be adjusted. However, if attaching a zoom lens and changing from wide angle to telephoto, the images may not be captured in proper focus, and so in such cases the flange back should always be adjusted by following the procedure given below.
1 Connect a cable between the MONITOR OUT connector of the camera and the VIDEO IN connector of a monitor.
2 Turn on the camera’s power.
Adjust the flange back while viewing the camera images on the monitor.
3 Use a Phillips screwdriver to loosen the two flange back locking screws.
4 Move the zoom lens to the telephoto setting, and then use the lens focus ring to adjust the focus.
5 Move the zoom lens to the wide angle setting, and then use the flange back adjustment dial to adjust the focus.
6 Move the zoom lens from wide angle to telephoto (repeating steps 4 and 5) and check that the images are properly focused. Then tighten the flange back locking screws.
