Chapter 5 Preparation
Adjusting the white shading of the lens
The white shading is adjusted as follows.
<Notes>
≥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).
1Attach the lens to the camera.
At this stage, do not forget to connect the lens cable.
2Set the electronic shutter to OFF and the gain to “L (0 dB).”
3If the extender is attached to the lens, release the extender function.
4Perform 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.

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