Preparations
Attaching a Lens
For information on handling lenses, refer to the lens’
operation manual.
Attaching procedure
1
Push the lens fixing lever upwards and remove the lens
mount cap from the lens mount.
2
Align the lens’ alignment pin with the notch in the
upper part of the lens mount and insert the lens into the
mount.
3
While supporting the lens, push the lens fixing lever
downwards to secure the lens.
4
Connect the lens cable to the LENS connector.
5
Secure the lens cable with the cable clamp.
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.
See “Displaying the focus assist indicators” on page 30
for the focus assist indicators.
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.
Adjusting procedure
1
Set the iris control to manual, and open the iris fully.
2
Place a flange focal length adjustment chart
approximately 3 meters 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 through 7 until the image is in focus at
both telephoto and wide angle.
9
Tighten the Ff ring lock screw.
Attaching a Viewfinder
When the viewfinder is attached, do not leave the camera
with the eyepiece facing the sun. Direct sunlight can enter
through the eyepiece, be focused in the viewfinder and
cause fire.
Attaching a viewfinder
The instructions are made using the HDVF-20A/200/
C30WR/C35W viewfinder as an example.
For details on the viewfinder, refer to the instruction
manual of the viewfinder.
