warmed gradually. Do the same when taking the
lens from a warm environment into a cold one.
zIn order to optimize aperture control, there are
occasions in which the aperture blades will move
during zooming, even when the aperture value is
set for aperture-priority AE or manual exposure,
etc.

2. Focusing/control ring
The focusing/control ring can be used as either a
focusing ring or a control ring.
Focusing/control ring
Focusing/control selector switch
Use as a Focusing Ring
Set the focusing/control selector switch to
FOCUS. Set the focus mode (AF/MF) using the
camera settings.
To shoot in autofocus (AF) mode, set the
camera's focus mode to AF.
To use only manual focusing (MF), set the
camera's focus mode to MF, and focus by turning
the focusing ring (focusing/control ring).
zThis lens does not have a focus mode switch.
zDelayed focus may occur if the focusing ring
(focusing/control ring) is quickly turned.
zWhen the AF does not operate after switching
the focus mode from [MF] to [AF] and when the
focus mode is not displayed on the camera’s
menu, turn the focus ring in the direction of
[Infinity] until the focusing position is within the
[AF in-focus range].
• It is not possible to switch the focus mode
to [AF] if the focus lens’s focusing position
is within the [MF-only range], at which the
focus can only be aligned in the MF mode.
• Refer to 3. Taking Closeup Shots in the
Manual Focusing (MF) Mode for further
details.

ENG-8
Use as a Control Ring
Set the focusing/control selector switch to
CONTROL. Set the control ring function using
the camera’s menu. The control ring can be
assigned the functions that are commonly
used with cameras, such as shutter speed and
aperture settings.
Please refer to the camera's instructions for
details on how to use the control ring.
zThe lens’ focusing ring (focusing/control ring) is
electronic.
zWith a camera capable of electronic full-time
manual focus, manual focusing is possible
in both One-Shot AF and Servo AF modes.
However, the camera settings need to be
changed.
zWhen AF operation is set to One-Shot AF,
manual focus is possible after autofocusing
has been completed by continuing to press the
shutter button halfway (electronic manual focus
function). However, the camera settings need to
be changed.
zWhen movie recording, the AF speed will be
slower than the still photo shooting mode. It is
possible to adjust the AF speed on the camera
by setting Movie Servo AF to [Enable].
Please refer to the camera's instructions for
details.

ENG-9
When using this lens, shots taken with the
camera’s manual focusing (MF) mode within a
range of less than 20 mm from the wide end
make the subject seem closer and larger than
with the autofocus (AF) mode.
The focusing distance ranges of the wide end
are shown below.
• AF in-focus range: 0.28 m/0.92 ft. to ∞
• MF in-focus range: 0.128 m/0.42 ft. to ∞
Focusing within a range of 0.128 m / 0.42 ft. to
less than 0.28 m / 0.92 ft. is possible only when
using the MF mode. (MF-only range)
zThe [MF in-focus range] will differ in accordance
with the focal length within a range of less than
20 mm from the wide end.
zRefer to the specifications on page 16 for details
on the range of focusing distances apart from
with wide-angle lenses.
zThe focusing distance represents the distance
between the [ ] mark (focal plane mark) on the
camera and the subject.
