Panasonic WV-CLR930 Mode D'emploi page 16

Use of "ABF" of "BACK-FOCUS SETUP" in the setup menu ( page 49) allows users to
adjust the focus optimally in the range of the capability to automatically follow the variation
in illuminance. (Note: The adjusted focal point is not necessarily the same as the optimal
focal point at the specified illuminance.)
• The out-of-focus level in the near-infrared light region may be higher than that in the
visible light region.
Setting "C/L ←→ B/W" of "BACK-FOCUS SETUP" to "AUTO" or "PRESET" in the setup
menu ( page 48) allows users to adjust the focus in both the near-infrared light and
visible light regions. (The variation in illuminance is not followed after focus adjust-
ment.)
How to use varifocal lens/zoom lens
• Reset the back focus position to the CS mount default position before the back focus
adjustment. (Press the right and left buttons among the operation buttons simultaneously,
or move the cursor to "MANUAL-ADJ" of "BACK-FOCUS SETUP" in the setup menu and
press the right and left buttons simultaneously after pressing the setting button.)
• Be aware that the adjustment method varies with varifocal lens or zoom lens models. For
further information, refer to the operating instructions for the lens to be used.
Notes:
• The adjustment procedure for general varifocal lenses is described as follows: For further
information, refer to the operating instructions for the lens to be used.
1. Display a subject that exists as far as possible (10 m or more recommended) to adjust
the back focus.
2. For 8-, or 10-fold magnification lenses, adjust the back focus after setting the zoom to
the WIDE end and setting the focus to the FAR end.
For 2-, or 3-fold magnification lenses, adjust the back focus after setting the zoom to
the TELE end and setting the focus to the FAR end.
3. Adjust the view angle and focus coarsely by adjusting the zoom and focus of the lens
to center a subject in the screen, and then perform the main adjustment of the back
focus ( pages 17 and 48).
• When a non-Panasonic lens that has an extended range for lens focusing is used, adjust
the back focus after setting the focus to a position at a short distance from the FAR end in
Step 2 described above. If adjustment is performed in the extended range, appropriate
adjustment cannot be obtained.
How to use fixed focus lens
• For a fixed focus lens with focus adjustment, adjust the back focus after setting the focus of
the lens to the FAR end.
