Adjusting the white shading

Follow the procedure outlined below when the white shading needs to be re-adjusted.

Adjustment method

<Notes>

O The method below can be used for the white shading adjustments with most lenses. However, with some very special lenses, a different adjustment method may be necessary.

O Even when the white shading has been adjusted, tinting may occur in the vertical direction near the lens aperture open position. This is a phenomenon which is inherent to lenses and optical systems and is not indicative of 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 set the gain to “L (0 dB).”

GAIN: L (0 dB)

SHUTTER: OFF

3 If the lens is provided with an extender, disengage the extender function.

Similarly, if the lens is provided with a ratio converter, disengage the ratio converter function.

4 1Perform the menu operations (pages 70 to 72), and display the “VF DISPLAY” screen of CAM MAIN MENU 2.

2Set ZEBRA1 DETECT to 70%, ZEBRA2 DETECT to 85% and ZEBRA2 to STOP.

(Default setting mode)

3Press the MENU button and close the menu

screen.

4Set the ZEBRA switch on the viewfinder to ON.

JOG dial button

5 Shoot a sheet of white paper devoid of color irregularities.

<Note>

Since flicker tends to occur under fluorescent lights, mercury lamps and other such lights, use a source of light such as sunlight or a halogen lamp which does not tend to produce flicker.

6 Set the lens aperture to manual, and adjust the lens aperture in such a way that ZEBRA fills the whole screen.

Check that the lens aperture is between F/4 and F/11.

<Notes>

O Since unevenness in the lighting will make it impossible for ZEBRA to fill part of the screen, try adjusting the lighting position, etc.

O Try adjusting the lighting position, etc. also when

the lens aperture is not between F/4 and F/11.

O Always be sure to leave the electronic shutter at OFF.
