Preparation Mounting the lens and Performing the Flange Back and White Shading Adjustments
Preparation
1 Raise the lens clamping lever and remove the mount
cap.
2 To mount the lens, align the indentation at the top
center of the lens mount with the center mark of the
lens.
3 Lower the lens clamping lever to clamp the lens.
4 Secure the cable through the cable clamp, and plug it
into the LENS connector.
5 Adjust the lens flange back.
Notes
z Please refer to the lens instruction manual for
guidance on lens handling.
z When the lens is removed, install the mount cap to
protect the device.
If images are not clearly focused at both telephoto and
wide-angle positions during zoom operations, adjust the
flange back (distance from the lens mounting surface to
the image formation surface).
Once adjusted, the flange back does not need to be re-
adjusted as long as the same lens is mounted on the
camera.
Note
Please also refer to the lens instruction manual for
directions on adjustment and locations of individual lens
parts.
1 Mount the lens on the camera.
Make sure you connect the lens cable.
2 Set the lens iris to manual, and fully open the iris.
3 Place the flange back adjustment chart about 3 m
from the lens and adjust the lighting on the chart to
obtain an appropriate video output level.
If the video level is too high, use the filters or the
shutter.
4 Loosen the F.f (Flange focus) ring clamping screw.
Note
F.b (Flange back) may be indicated on some lenses.
5 Set the zoom ring to the telephoto 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.
7 Set the zoom ring to the wide-angle position and turn
the F.f ring to bring the chart into focus.
While focusing, take care not to move the distance
ring.
