Chapter 5 Preparation — Mounting and adjusting the lens

For a normal lens

Approximately 3 m

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

2 Set the lens iris to manual, and fully open the iris.

3Place 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.

4Loosen the F.f (Flange focus) ring clamping screw.

5Set the zoom ring to the telephoto end position, either manually or by electric drive.

6 Aim the lens at the flange back adjustment chart and turn the distance ring to bring the chart into focus.

7Set the zoom ring to the wide-angle end position and turn the F.f (Flange focus) ring to bring into focus. At this time, do not move the distance ring.

8Repeat steps 5 to 7 until the lens is in focus at both the telephoto and wide-angle positions.

9Firmly tighten the F.f (Flange focus) ring clamping screw.

@@NOTE

tt F.b (Lens flange back) ring may be indicated on some lenses as the F.f (lens flange focus) ring.

White shading compensation

Adjusting the white shading

This is a method of combining the sawtooth shaped waveform and parabola waveform to compensate to a flatter waveform based on the respective R, G and B waveforms of the video signal.

We recommend adjusting the R, G and B waveforms in the horizontal and vertical directions while monitoring them on the waveform monitor. Be sure to set [DS.GAIN] and [D.ZOOM] to [OFF] before adjusting white shading.

1Set the camera for adjustment.

1)Mount the lens on the camera.

ffMake sure to connect the lens cable.

2)Set the <SHUTTER> switch to <OFF>, and the <GAIN> switch to <L> (0 dB).

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

4)Make sure that [HD] is set in the main menu → [PAINT] → [GAMMA] → [GAMMA MODE SEL]. Also, make sure that [ZEBRA1 DETECT] is set to [70%], [ZEBRA2 DETECT] is set to [85%], and [ZEBRA2] is set to [SPOT] in the main menu → [VF] → [VF DISPLAY], and then close the menu screen.

ffChange the settings if they are different.

5)Set the <ZEBRA> switch in the viewfinder to <ON>.
