2. Preparation
Mounting and Adjusting the Lens
[Note]
When connecting or disconnecting the lens cable to this
connector, power off the camcorder first.
Attaching a Lens
The lens is available separately.
This section describes an example lens
attachment.
For information about attaching a lens, refer to the
operation manual for the lens.
1
Push the lens locking lever up and remove
the lens mount cap from the lens mount.
2
Align the center pin on the lens with the
center slot in the lens mount, and insert
the lens into the mount.

Holding the lens in place, push the lens
locking lever down to lock the lens.
[CAUTION]
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 below.

Connect the lens cable to the LENS
connector.
5
Secure the lens cable with the cable
clamp.
If an aberration correction lens is
attached
The aberration correction function is activated
automatically.
1)
Starting the camcorder with
1
an aberration correction lens may require
more time than normal because of data
loading at start-up.
Contact a Sony service representative for
information about aberration correction
lenses.
1) The aberration correction function does not operate
if Maintenance >Camera Config >ALAC in the setup
menu is set to Off.
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, also called flange-back).
Make this adjustment just one time after
mounting or changing the lens.
When carrying out the adjustment, use a
flange focal length adjustment chart as the
3
subject.
[Notes]
ˎ If you use a subject with insufficient contrast, or move
ˎ
the camcorder or subject during adjustment, this will
cause an adjustment error.
ˎ Place the subject (the flange focal length adjustment
ˎ
chart) so that it appears at the center of the screen at
the telephoto end. Arrange it so that no nearby object
(no object closer to the camera than the chart) enters
the screen at the wide-angle end.
1
Set the iris to manual.
2
Place the supplied flange focal length
adjustment chart about 3 m (10 ft) in front
of the camera.
3
Open the iris.
The depth-of-field is reduced when the
iris is open, making adjustment easier.
4
Loosen the fixing screws on the F.f or F.B
ring (flange focal length adjustment ring).
5
Use manual or power zoom to set the lens
to telephoto.
6
Point the camcorder at the chart by
turning the focus ring and focus on it.
7
Set the zoom ring to wide angle.
8
Turn the F.f or F.B ring until the chart is in
focus, being careful not to disturb the
focus ring.

5
Repeat steps
focus all the way from wide angle to
telephoto.
10
Tighten the F.f or F.B ring fixing screws.
