5-3 Adjusting the white shading of
the lens
Method to correct the waveform to be more flat by
combining the sawtooth-shaped waveform and the
parabola waveform when watching the respective
waveforms of R, G and B of the video signals.
White shading adjustment is disabled when the DS. GAIN is
turned ON or the LINE MIX GAIN function operates. Adjust
the white shading in the following manner after turning OFF
the DS. GAIN and releasing the LINE MIX GAIN function.
<Note>
Coloring may occur in the vertical direction near where the
lens aperture is open even when the white shading has been
adjusted. This is something that is inherent to lenses and
optical systems and is therefore not indicative of a failure or
malfunctioning.
2
Set the electronic shutter to OFF and the gain to “L (0
dB).”
1
Attach the lens to the camera.
At this stage, do not forget to connect the lens cable.
4
Perform a menu operation to open the <GAMMA>
screen from the PAINT page, and check that “STD” is
selected as the GAMMA MODE SEL item setting. Then
open the <VF DISPLAY> screen from the VF page,
check that the settings selected for the ZEBRA1
DETECT item, ZEBRA2 DETECT item and ZEBRA2
item match the settings shown in the figure below. If
they differ, make the appropriate changes, and then
close the menu screen.
3
If the extender is attached to the lens, release the
extender function.
5
Set the ZEBRA switch on the viewfinder to ON.
6
Shoot a white sheet of paper with no unevenness of
color.
<Note>
Since fluorescent lights, mercury lamps and other such
kinds of lighting tend to flicker, use a light source which
is free from flicker such as sunlight or a halogen lamp.

7
Set the lens aperture control to manual, and adjust it so
that the zebra pattern covers the whole screen. Check
that the lens aperture is between F4 and F10.
<Notes>
The zebra pattern will not cover the whole screen if
there is any unevenness in the lighting. In this case,
make adjustments to the position of the lighting, etc.
