• Set the camera’s power switch to OFF when attaching or detaching the lens.
• Attach the lens cap before detaching the lens from the camera.
• After detaching the lens, place the lens with the rear end up and attach the dust cap to prevent the lens surface and contacts from getting scratched. Make sure the lens and dust cap mount indexes are aligned when attaching the dust cap.
• Contacts that are scratched, soiled, or have fingerprints on them may result in faulty connections or corrosion, which may lead to malfunctions. If the contacts get soiled, clean them with a soft cloth.

Focusing/control ring

The focusing/control ring can be used as either a focusing ring or a control ring.

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).

•  This lens does not have a focus mode switch. Delayed focus may occur if the focusing ring (focusing/control ring) is quickly turned.

• When 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.

Focusing/control ring

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.

• The lens’ focusing ring (focusing/control ring) is electronic.

• With 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.

• When 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.

• When 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.

Taking Closeup Shots in the Manual Focusing (MF) Mode

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)

• The [MF in-focus range] will differ in accordance with the focal length within a range of less than 20 mm from the wide end.
• Refer to the specifications on page 16 for details on the range of focusing distances apart from with wide-angle lenses.
• The focusing distance represents the distance ] mark (focal plane mark) on the  camera and the subject.

Taking Closeup Shots in the Manual Focusing (MF) Mode
Take the following steps for shooting in the [MF-only range].

1. Set the focusing/control selector switch to FOCUS.
2. Set the focusing mode on the camera to [MF].
3. Set the focal length to a wider setting than 20mm with the zoom ring.
4. Turn the focusing ring in the short-range direction to move the focusing position from [AF in-focus range] to [MF-only range]. (*Notes 1 & 2)
5.  Manually focus on the subject while in the [MF-only range] and take the picture.

Note 1: It is possible to move the focus to the [MF-only range] with the use of the lens’s electronic manual focusing function1 or
the electronic full-time manual focusing function2 with the camera’s focus mode still set at [AF].
The camera focus mode will automatically switch to [MF] when the focusing position enters the [MF-only range] during this. Note 2: It is not possible to switch the focus mode to [AF] when the focusing position is in the [MF-only range].  In order to switch to [AF], turn the focusing ring in the direction of [Infinity] until the focusing position enters the [AF in-focus range].

• 1 A function that enables the focus to be adjusted manually if the shutter button continues to be pressed halfway after performing AF operations when the camera’s AF operation mode is set at One-Shot AF.

• 2 A function that enables the focus to be adjusted manually in both the One-Shot AF and Servo AF modes. However, it is necessary to amend the camera settings for both functions 1 and 2. Please refer to the camera’s instructions for details.
  The following limitations are in effect when the focus point is within the [MF-only range].

  • The image quality will decline compared to the [AF in-focus range]. It is therefore recommended that you shoot while checking the images after each shot.
  • Detection accuracy levels for the focus guide function will be lowered. Use the focus guide function within the [AF in-focus range].
  • It is not possible to align the focus when taking remote shots with PCs and smartphones.

Taking Closeup Shots in the Manual Focusing (MF) Mode
It is possible to check the focusing position with the use of the camera’s focusing distance display function*3.

The illustrations on the left above are enlarged images of the camera’s focusing distance display areas*4.

• The short-range direction is on the left and the infinity symbol on the right indicates the infinity direction.

• The orange vertical line shown in (1) indicates the current focusing position.

• The range of the white line shown in (2) indicates the range of focusing positions that can be used for shooting.

• The range shown in (3) is the [MF-only range] within which the focus can be aligned only when in the [MF] mode.

• The range shown in (4) is the range within which the focus can be aligned when in both the [MF] and [AF] modes. The focus can only be aligned within the range shown in (4) when in the [AF] mode.

• 3 Refer to the camera’s instruction manual for details on displaying the [Focusing Distance Display].

• 4 The [AF in-focus range] and [MF in-focus range] will differ in accordance with the focal length, which means that the focusing distance display will vary with the focal length.

Zooming

• Be sure to finish zooming before focusing. Zooming after focusing can affect the focus.
• Blurring may temporarily occur if the zoom ring is quickly turned.
• Please be careful not to let your fingers get caught in between the lens’ front and the focusing/control ring when zooming.

Image Stabilizer

Set the image stabilizer switch to ON when you want to use the Image Stabilizer.

• This function provides image stabilization appropriate for shooting conditions (such as shooting still subjects and panning shots).
• The Image Stabilizer will work in combination with cameras with in-body Image Stabilizer.
• Set the image stabilizer switch to OFF when you are not going to use the Image Stabilizer.
• The Image Stabilizer cannot compensate for a blurred shot caused by a subject that moved.
• The Image Stabilizer may not be fully effective if you shoot from a violently shaking vehicle or other transportation.
• When using a tripod, it is recommended that you set the Image Stabilizer to OFF.
• Even with a monopod, the Image Stabilizer will be as effective as during hand-held shooting. However, depending on the shooting conditions, there are cases in which the Image Stabilizer effect may be less effective.

Image Stabilizer

The Image Stabilizer for this lens is suited to hand-held shots in the following conditions.

•  In semi-darkened areas such as indoors or outdoors at night.
•  In locations where the flash cannot be used, such as art museums and theater stages.
•  In situations where your footing is uncertain.
•  In situations where fast shutter speed settings cannot be used.

Panning shots of vehicles, trains, etc.
It compensates for vertical camera shake during panning shots in a horizontal direction, and compensates for horizontal camera shake during panning shots in a vertical direction.

Hood (Sold separately)

The custom lens hood reduces unwanted light that causes flare and ghosting and protects the front of the lens from rain, snow, and dust.

Attaching the Hood
Align the red attachment position mark on the hood with the red dot on the front of the lens, and then turn the hood in the direction of the arrow until the red dot on the lens is aligned with the stop position on the hood and the hood is firmly attached.
