Chapter 5 Preparation — Mounting and adjusting the lens

Place the flange back adjustment chart approximately 3 m

from the lens and adjust the lighting on the chart to obtain

an appropriate image output level.

If the image level is too high, use the filters or the shutter.

Loosen the F.f (Flange focus) ring clamping screw.

NOTE

tF.b (Flange back) may be indicated on some lenses.

Set the zoom ring to the telephoto position, either manually

or by electric drive.

Aim the lens at the flange back adjustment chart and turn the

distance ring to bring the chart into focus.

Set the zoom ring to the wide-angle position and turn the F.f

(Flange focus) ring to bring the chart into focus.

At this time, do not move the distance ring.

Repeat steps 5 to 7 until the lens is in focus at both the

telephoto and wide-angle positions.

Firmly tighten the F.f (Flange focus) ring clamping screw.

White shading compensation

Three optionally adjustable data items [USER1], [USER2], and [USER3] can be used for white shading compensation with the camera. Set these data
items from the [SHADING SELECT] item on the setting menu [LENS SETUP] screen. Shading compensation is not performed when set it to [OFF].

NOTE

tWhen white shading adjustment is performed while image is being disturbed due to the generator lock, adjustment may not be performed

correctly. Try white shading adjustment again after the image returns to normal.

Selecting white shading data

Select the [SHADING SELECT] item on the setting menu

[LENS SETUP] screen, and press the jog dial button.

For details, refer to “Setting menu basic operations” (page 118).

Adjusting the white shading

NOTE

tColoring may occur in the vertical direction near where the lens aperture is open (OPEN) even when the white shading has been adjusted,

but this is something that is inherent to optical systems and is therefore not indicative of a malfunction.

Set the camera for adjustment.

1) Mount the lens on the camera.

Make sure to connect the lens cable.

2) Set the shutter switch to OFF and the gain to 0 dB.

3) If the lens is equipped with extender function, release the extender

function.

4) Check that either [USER1], [USER2], or [USER3] is set with the

[SHADING SELECT] item on the setting menu [LENS SETUP]
screen.

5) Select [EXECUTE] at the [SHADING (USER)] item, and press the

jog dial button.
