Adjustment > Adjustment Procedure
6-4-5 Autofocus
Preparations:
1) Use the backfocus chart vertically (portrait mode) as
shown in Fig. 6-4-3.
2) Point at backfocus chart 1500mm ± 5 mm away from the
lens surface: Measure the distance precisely.
3) Set the zoom to telephoto end, and make sure that the
center of backfocus chart appears.
4) If an illuminometer is available and the brightness of
illumination can be varied, set the illuminance of
backfocus chart surface to 200-400 lx. This setting is not
necessary if the brightness of illumination cannot be
varied: Perform adjustment under indoor light that is as
bright as possible.
Procedure:
1) Choose AUTO FOCUS on the adjustment menu screen.
2) Click the EXECUTE button on ADJUST MENU screen
to start adjustment.
3) When adjustment is complete, the ADJUSTMENT
FINISHED dialog will appear: Click the OK button in
dialog to restore the ADJUST MENU screen.
If the AF ADJUSTMENT ERROR dialog appears, click
the OK button in dialog, perform the following
troubleshooting, and then execute readjustment:
a) Increase the illumination.
b) Set the distance between the backfocus chart and
lens surface precisely to 1500mm ± 5 mm.
If the AF adjustment error dialog still appears even after
troubleshooting, the connection of lens unit may be
incorrect or the unit may be faulty.
