<About the flange-back length adjustment>
The flange-back length is the distance between flange surface and the focal point.
Important:
• The "ABF" (auto back focus) function is for adjustment of the flange-back length at the installation, and for focus
compensation when shifting between color and B/W after the installation. This function is not supposed to be
used for sequential action such as the auto focus function.
• It is necessary to adjust the flange-back length again when images become out-of-focus caused by aging of the
lens and the environment change, etc.
Note:
The flange-back length adjustment can be performed using the operation buttons on the camera (
☞
operating
instructions).
