Chapter 5 Preparation (continued)

Adjusting the Lens White Shading

Take the following steps to adjust the white shading:

<Note>

Vertical coloring may occur near the open position of the lens iris, even after adjusting the white shading. This phenomenon, however, is a characteristic of the lens or optical system. It does not indicate a malfunction.

1Mount the lens on the camera. Be sure to connect the lens cable.

2Set the electronic shutter to [OFF], the gain to [L (0dB)], and the ASPECT option to “16:9”. Select the ASPECT option from the SYSTEM MODE screen on the SYSTEM SETTING page.

3If the lens has an extender, disable the extender feature.

4Operate the MENU and go to the PAINT page to open the <GAMMA> screen. Confirm that the GAMMA MODE SEL is set to STD. From the VF page, open the <VF DISPLAY> screen to confirm that ZEBRA1 DETECT, ZEBRA2 DETECT, and ZEBRA2 are set as shown in the diagram below. If they are not, correct the settings and then close the MENU screen.

5Set the Viewfinder ZEBRA switch to ON.

6Aim the lens at a sheet of white paper that has no color shading.

<Note>

Flickering naturally occurs when fluorescent, mercury or other such lamps are used for lighting. Therefore, use a light source that does not flicker, such as sunlight or halogen lamps.

7Set the lens iris to manual and adjust the lens iris so that the ZEBRA pattern covers the entire screen.

Make sure that the lens iris is set between F4 and F11.

<Notes>

z The ZEBRA pattern will not cover the entire screen if the lighting is uneven. In this case, adjust the lighting (e.g., change the position of the light source).

z Even if the lens iris is not set between F4 and F11, adjust the lighting (e.g., change the position of the light source).

z Make sure that the electronic shutter is set to OFF.

8Set the WHITE BAL selector switch to A or B, and execute Auto White Balance (AWB) with the AUTO W/B BAL switch.

Next, execute Auto Black Balance (ABB) with the AUTO W/B BAL switch.

Repeat Auto White Balance (ABB) with the AUTO W/ B BAL switch.

9 Repeat the adjustment described in Step 7.

 

10Activate the MENU and go to the MAINTENANCE page

 

to open the <WHITE SHADING> screen.

 

5

11 Turn the JOG Dial button to move the cursor to

DETECTION (V.SAW). Then, press the JOG Dial

 

 

button to execute white shading compensation.

 

12Press the JOG Dial button and the following message appears.

13Turn the JOG Dial button to move the cursor to [YES]. Then press the JOG Dial button.

[ACTIVE] appears on the screen to indicate that the white shading automatic adjustment is running. [W-SHD OK] appears when the adjustment is completed.

<Note>

This compensation may not be possible when [LEVEL OVER] is displayed, depending on the KNEE setting. In this case, first narrow the lens iris or set the OUTPUT switch AUTO KNEE to OFF. Next, activate the MENU to open the PAINT screen. From the PAINT screen, open the <KNEE/LEVEL> screen and set MANUAL KNEE to OFF. Then repeat Steps 4 to 9.

After [W-SHD OK] is displayed, re-set MANUAL KNEE back to ON.

14If the lens has an extender or a ratio converter, enable the feature and repeat Steps 7 to 13 for each feature. Three patterns of compensation values (with an extender, with a ratio converter, and without any features) will be stored as one set of lens file data in the camera-recorder.
