 Attaching the Lens Hood

It is recommended that you use a lens hood to
reduce flares and ensure the maximum image
quality.
Loosen the hood-locking knob on the lens
hood (1), and then put the lens hood over
the front of the lens (2). Make sure that
the lens hood is not slanted and is fully
engaged, and then tighten the hood-locking
knob.

back into place, make sure that the serial numbers
on both the servo zoom unit and the lens are
identical, and then fit the servo zoom unit aligning
the three screw holes together. When tightening
the screws, apply the specified tightening torque
(0.15 - 0.25 Nm). (See illustration -a.)

 Focusing
AF/MF mode
To place the lens into AF/MF mode, set the focusing
ring to the position .
While the lens is in AF/MF mode and the camera is
in AF mode, autofocus shooting is available.
While the camera is in MF mode, you must manually
adjust the focus.
• When autofocusing is used, image angle variation
(breathing) may be apparent during focusing
depending on the state of the subject. In such a case,
adjust the focus manually.
FULL MF mode
To place the lens into FULL MF mode, set the
focusing ring to the position .
While the lens is in FULL MF mode, you can
manually adjust the focus apart from whether the
camera is in AF or MF mode.
The rotation range of the focusing ring is limited
and the focus is adjusted in accordance with the
distance scale movement.
• The distance scale is only a rough guide.
• When you move the focus ring from AF/MF mode 
to FULL MF mode , focus is adjusted to the distance
indicated on the distance scale.
