the white shading is now being automatically
compensated. Upon completion of the adjustments, W-
SHD OK is displayed.
<Note>
Depending on the KNEE settings, “LEVEL OVER” may
appear on the screen and white shading compensation
may not be possible. If this is the case, either stop down
the lens or set the AUTO KNEE OUTPUT switch to OFF,
then perform a menu operation to open the
<KNEE/LEVEL> screen from the PAINT screen, select
“OFF” as the MANUAL KNEE item setting, and repeat
steps 4 through 9. After “W-SHD OK” has appeared on
the display, select “ON” again as the MANUAL KNEE

If the extender is attached to the lens, turn on the
extender function or, alternatively, if the ratio converter is
attached, turn on the ratio converter function. In either
case, repeat steps

The compensation values for 3 patterns—namely, when
the lens extender is used, when the ratio converter is
used and when neither the lens extender nor ratio
converter is used—are stored in the unit as the data of
one lens file.
This now completes the white shading adjustments.
The adjustment values are now stored in the non-volatile
memory so that even when the unit’s power is turned off,
there will be no further need to perform the white shading
adjustment.
