Adjusting the Flange Focal Length
Adjustment of the flange focal length (the distance between
the lens mount attachment plane and the imaging plane) is
necessary in the following situations:
• The first time a lens is attached
• When changing lenses
• If the focus is not sharp at both telephoto and wide angle
when zooming
The flange focal length can be more precisely adjusted by
using the focus assist indicators.
For details about focus assist indicators, see “Displaying the
focus assist indicators” (page 13).
The various parts of the lens used in adjusting the flange focal
length are in different positions on different lenses. Refer to
the operation manual for the particular lens.
Adjustment procedure
1
Set the iris control to manual, and open the iris fully.
2
Place a flange focal length adjustment chart
approximately 3 meters (10 ft) from the camera and
adjust the lighting to get an appropriate video output
level.
3
Loosen the Ff (flange focal length) ring lock screw.
4
With either manual or power zoom, set the zoom ring
to telephoto.
5
Aim at the flange focal length adjustment chart and
turn the focus ring to focus the image.
6
Set the zoom ring to wide angle.
7
Turn the Ff ring to bring the chart into focus. Take
care not to move the distance ring.
8
Repeat steps 4 to 7 until the image is in focus at both
telephoto and wide angle.
9
Tighten the Ff ring lock screw.
