1
Attach the lens to the camera.
At this stage, do not forget to connect the lens cable.
2
Set the lens aperture to manual and open the aperture.
3
Set the lighting in such a way that the appropriate video
output level is achieved at a distance of about 3 meters
away from the chart used for the flange back adjustment.
If the video level is too high, use the filters and shutter.
5
Set the zoom ring to the telephoto position either
manually or electrically.
6
Shoot the chart used for the flange back adjustment, and
turn the distance ring to adjust the focus.
8
Repeat steps 5 to 7 until the focus is adjusted at both the
telephoto and wide-angle positions.
9
Tighten the screw securing the F.f ring.
7
Set the zoom ring to the wide-angle position, and turn the
F.f ring to adjust the focus.
Take care not to move the distance ring during this
process.
4
Loosen the screw securing the F.f (flange focus) ring.
On some lenses, this may be marked as F.b (flange back)
ring.

Adjusting the lens flange
If the subject is not focused properly in the telephoto and
wide-angle modes during zoom operations, adjust the flange
back (distance from the lens mounting surface to the image-
forming surface).
Once this adjustment is done, it need not be redone unless
the lens is replaced.
For details on the adjustment method and lens positions, refer
also to the operating instructions that accompany the lens.

Adjusting the white shading of the lens
The white shading is adjusted as follows.
≥
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.
≥ The white shading cannot be adjusted when the digital
zoom function is working. To adjust the white shading,
release the digital zoom function first (by pressing again the
USER button to which D.ZOOM is allocated).
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
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.
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.
