9 Repeat step 7.
10 Using the menu operation, open the <WHITE SHADING> screen from the MAINTENANCE page and a range of items from R H SAW item to B V PARA item, so that the waveform is more flat.

1 Set the WHITE BAL selector switch to “A” or “B,” and use the AUTO W/B BAL switch to adjust the white balance automatically (AWB).
2 Use the AUTO W/B BAL switch to adjust the black balance automatically (ABB).
3 Again, use the AUTO W/B BAL switch to adjust the white balance automatically (AWB).

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
z 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. z Make adjustments to the position of the lighting, etc. also when the lens aperture is not between F4 and
F10.
z Be absolutely sure to leave the electronic shutter at OFF.

9 Firmly tighten the F.f ring clamping screw.

Adjusting the Lens White Shading

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.

1 Attach the lens to the camera.

At this stage, do not forget to connect the lens cable.

2 Set the electronic shutter to OFF and the gain to “L (0 dB).”

3 If the extender is attached to the lens, release the extender function.

4 Perform a menu operation to 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.

11 When the lens has an extender or ratio converter, repeat steps 7 - 9 to enable the extender or ratio converter function. The camera-recorder stores, as one lens file data item, three different correction values for the following: a lens with an extender, a lens with a ratio converter, and a lens with neither of them.
