4) Confirm that the [SCENE FILE] menu → [GAMMA MODE SEL] → [HD] is set.
5) Confirm that the [VIDEO OUT/LCD/VF] menu → [EI ASSIST] is set to as follows.
f Change the setting if it is different.
[ZEBRA1 DETECT]: [70%]
[ZEBRA2 DETECT]: [85%]
[ZEBRA2]: [SPOT]
6) Set the <ZEBRA> switch in the viewfinder to <ON>.

Set the screen.
1) Shoot a white sheet of paper with no unevenness of color for the whole screen.
2) Set the lens aperture to manual, and adjust it so that the zebra pattern covers the whole viewfinder screen.
f Make sure that the lens aperture control is between F4 to F11.
f Adjust the position of the lighting because the zebra pattern will not cover the whole screen if there is any unevenness in the lighting.
f Make adjustments to avoid several light sources of different color temperature (e.g. fluorescent lights and halogen lamp) from illuminating on
the white paper.

Adjust the white balance/black balance.
1) Set the <WHITE BAL> switch to <A> or <B>, and use the <AUTO W/B BAL> switch to adjust white balance automatically (AWB).
2) Use the <AUTO W/B BAL> switch to adjust black balance automatically (ABB).
3) Use the <AUTO W/B BAL> switch to adjust white balance automatically (AWB) again.
4
Perform the steps 2 - 2) again.
5
Adjust white shading.
Set all of the following items in the [CAMERA] menu → [WHITE SHADING] to generate a waveform as flat as possible.
f [R H SAW]
f [R H PARA]
f [R V SAW]
f [R V PARA]
f [G H SAW]
f [G H PARA]
f [G V SAW]
f [G V PARA]
f [B H SAW]
f [B H PARA]
f [B V SAW]
f [B V PARA]

If the lens is equipped with an extender function, turn on the extender function and repeat steps 2 to 5.
Adjustment values are stored on the camera as a single lens file data using two patterns for when the lens is equipped and not equipped with the
extender function.
Adjustment values are saved in memory, so there is no need to re-adjust white shading even after turning the camera off.
@
NOTE
t Coloring may occur in the vertical direction near where the lens aperture is open (OPEN) even when the white shading has been adjusted, but this is
something that is inherent to optical systems. This is not a malfunction.
t Since fluorescent lights, mercury lamps, and other such kinds of lighting tend to flicker, use a light source which is less subject to flickering such as
sunlight or a halogen lamp.
t Make adjustments to the position of the lighting, etc. when the lens aperture is not between F4 and F11.
t Make sure to leave the <SHUTTER> switch at <OFF>.
Chromatic aberration compensation function (CAC)
The chromatic aberration compensation function minimizes color smearing in peripheral images. The registration error that is caused mainly due to
slight chromatic aberration that cannot be completely compensated by the lens is automatically compensated by the camera.
The chromatic aberration compensation function will automatically start to operate when a chromatic aberration compensation function compatible lens
is mounted.
