Preparing the Lens
Mounting the lens
Mount the lens using the following procedure.
For information about using the lens, refer to the
operating instructions for the lens.
1
Push the lens locking lever up 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 locking lever
down 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. It is
recommended that the lens mount securing rubber be
put on the lens-locking lever as illustrated above.
4
Connect the lens cable to the LENS connector.
Connecting the lens cable to the LENS connector
when the camcorder is powered may cause a
malfunction of the camcorder or the lens. Turn off the
camcorder before connecting the LENS connector.
5
Secure the lens cable with the cable clamps.

It is necessary to adjust the flange focal length (the
distance from the lens flange to the plane of the image
along the optical axis) in the following cases.
• When a lens is fitted for the first time
• After changing lenses
• When during zoom operations the focus does not match
properly from telephoto to wide angle
1
Set the iris selector to the M (Manual) position.

Turn the iris ring to open it.
Adjust the light or the ND filter so that an appropriate
brightness is obtained with the iris open.

Place the supplied flange focal length adjustment test
chart at a range of about 3 meters (10 feet), and adjust
the light so that an appropriate video level is obtained
with the iris open.
