7-3 Mounting the Lens
For information about using the lens, refer to the lens
manual.
1
Push the lens mount lever upward and remove the lens
mount cap from the lens mount.
2
Align the center slot in the lens mount with the center
pin on the lens and insert the lens into the mount.
3
Holding the lens in place, push the lens mount lever
downward to mount the lens.
If the lens is not firmly locked, it may come off while
the camcorder is being used. This could cause a serious
accident. Make sure the lens is firmly locked.
4
Connect the lens cable to the LENS connector.
Connecting a cable to the LENS connector while in
powered status may cause a malfunction or damage the
unit. Turn off the power before you make a connection
with the LENS connector.
5
Secure the lens cable with the cable clamps.
7-4 Adjusting the Flange
Focal Length
If the lens does not stay in focus properly as you zoom
from telephoto to wide angle, adjust the flange focal length
(the distance from the plane of the lens mounting flange to
the imaging plane). Make this adjustment after mounting
or changing the lens.
Adjusting the flange focal length
The position of the controls for adjusting the flange focal
length vary somewhat from lens to lens. Check the
identification of the various controls in the lens manual.
1
Set the iris to manual.
2
Open the iris. Place the flange focal length adjustment
chart about 3 m (10 ft) away from the camera, lit well
enough to provide a satisfactory video output level.
3
Loosen the fixing screws on the F.f or F.B ring (flange
focal length adjustment ring).
4
Use manual or power zoom to set the lens to telephoto.
5
Point the camera at the chart by turning the focus ring
and focus on it.
6
Set the zoom ring to wide angle.
7
Turn the F.f or F.B ring until the chart is in focus, being
careful not to disturb the focus ring.
8
Repeat steps
4
to
7
until the chart stays in focus all the
way from wide angle to telephoto.
9
Tighten the F.f or F.B ring fixing screws.
