Attaching and Detaching the Lens

Attaching the Lens
Align the lens mount indexes of the lens and camera, and turn the lens clockwise until you hear a click.
Detaching the Lens
Turn the lens counterclockwise while pressing the camera’s lens release button. Detach the lens once it has stopped turning.
Please refer to the camera’s instructions for details.

• 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.
• When the power switch of the camera is set to OFF, the focus lens pushed forward is automatically stored. * Do not detach the lens until the lens is completely stored.
• 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.
  * When the lens storage is set to ON on the camera.

Setting the focus mode

To shoot in autofocus (AF) mode, set the focus mode switch to AF.
To use only manual focusing (MF), set the focus mode switch to MF, and focus by turning the focusing ring.

• Quickly turning the focusing ring may result in delayed focus.
• Due to the structural characteristics, the focus lens driving speed may vary according to the variation in the air temperature and posture.
• Do not touch the operating part in the front of the lens while the focus lens is operating. If external pressure is applied to the moving part, the lens initialization may be performed to return the focus lens to the correct position for control purposes.
• The lens’ focusing ring is electronic.
• When AF operation is set to [ONE SHOT], manual focus is possible after autofocusing has been completed by continuing to press the shutter button halfway. (Full-time manual focus) However, the camera settings need to be changed.

Control Ring

The control ring can be assigned the functions that are commonly used with cameras, such as shutter speed and aperture settings.

The click action of the control ring allows you to have a sense of how much it is being turned.
Please refer to the camera’s instructions for details on how to use the control ring.

• There are cases in which the sound of control ring operations may be recorded when shooting movies.
• The clicking sensation of the control ring can be removed by the Canon Service Center. (chargeable)

image Stabilizer

This function provides image stabilization appropriate for shooting conditions (such as shooting still subjects, panning shots, and close- up (macro) shooting).

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

• Set the image stabilizer switch to OFF when you are not going to use the Image Stabilizer.
  The shorter the focusing distance is, the less the image stabilizer effect.
• 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 switch 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.
• When shooting a still subject, it compensates for camera shake in all directions.
• 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.

The Image Stabilizer for this lens is suited to handheld shots in the following conditions.

• In semi-darkened areas such as indoors or outdoors at night.
• In locations where a 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.

Hand-held Close-up Macro Shooting

This lens allows users to focus rom In Inity to a magnification of 0.5x for close-up (macro) shooting.
Hold the camera steadily
Hold the camera steadily as shown in the illustration on the right when taking hand-held close-ups (macro), and shoot carefully to minimize camera shake and prevent focus blurring.
Taking photographs using servo AF
It is recommended that the camera AF operation is set to [Servo AF] when taking close-up (macro) shots. Refer to the camera’s instructions for further details.

It is necessary to be careful with the following during close-up (macro) shooting.

• Camera shake creates more impact than on normal shots, and the effects of the image stabilizing function are reduced.
• Depth of field becomes extremely shallow when taking close-up (macros) shots, and the focus may blur if the camera is moved forward or backward.
• The minimum focusing distance (minimum distance between the subject and the imaging area) is 0.17 m/0.56 ft. The working distance (distance between the front end of the lens and the subject) is 70 mm/2.76 in.

Exposure When Taking Close-up (Macro) Shooting

Setting the Exposure
When taking photographs using TTL metering, no exposure compensation is necessary because the light coming through the lens is measured.  With TTL metering, photographing with AE (auto exposure) is possible at all focusing distances. Just select the desired picture-taking mode, then check the shutter speed and aperture before taking a picture.
Magnification and Effective f-number
The aperture displayed on the camera assumes that the focus is set to infinity (00). The actual aperture (effective f-number) becomes darker (effective f-number increases) at closer focusing distances (magnification increases). This has almost no influence on the exposure for normal picture-taking. However, for close-up (macro) shooting, the change in the effective f-number is more than negligible.

When deciding the exposure using a hand-held exposure meter, apply the following exposure factor.

Magnification	1:5	1:3	1:2
Focusing distance (m/ft.)	0.27/0.89	0.20/0.66	0.17/0.56
Effective f/No.	2.1	2.2	2.4
Exposure factor (stops)*	+1/3	+2/3	+1
	+1/2	+1/2	+1

* Upper values: 1/3 stops. Lower values: 1/2 stops.
Conditions of the subject are very important when deciding on the correct level of exposure for close-up (macro) shooting.
It is therefore recommended that you change the exposure level as much as possible during shooting, or that you take pictures while checking the images on the camera’s LCD monitor.
During close-up (macro) shooting, it is recommended that you use either the aperture- priority AE (Av) mode or manual exposure (M) mode, in which adjustment of the depth of field and exposure is easier.

Hood (Sold separately)

The custom lens hood cuts out unwanted light and protects the front of the lens from rain, snow, and dust.
Screw the hood firmly and correctly onto the front end of the lens.

• If the hood is not attached properly, vignetting (darkening of the perimeter of the picture) may occur.
• Turn OFF the power of the camera before attaching or detaching the hood.

Filters (Sold separately)

You can attach filters to the filter mounting thread on the front end of the lens or the front end of the hood.

• Only one filter may be attached.
• If you need a polarizing filter, use the Canon Circular Polarizing Filter PL-C B.
• Turn OFF the power of the camera before attaching or detaching a filter.

Close-up lenses (Sold separately)

Attaching a 250D/500D Close-up Lens enables close-up photography. It provides the following magnifications.

• 250D: 0.14 to 0.62x
• 500D: 0.07 to 0.56x
  MF mode is recommended for accurate focusing.

Macro Flash (Sold separately)

The Macro Ring Lite MR-14EX II or Macro Twin Lite MT-26EX-RT enables flash photography up to 0.5x magnification in E-TTL II autoflash mode. When using a macro flash and filter at the same time, attach the flash head to the lens while the filter is attached to the thread for attaching the filter in the front end of the lens.

• If a filter is attached to the macro flash, the front end of the lens and filter contact, hinders focusing. It also may damage the filter or cause the lens to fail.
• For how to use the MR-14EX II and MT-26EX- R T, please refer to the site’s instructions.
• When the MR-14EX II is in use
• Effective Flash Range (Reference)
• When the MT-26EX-RT is in use
  The MT-26EX-RT’s flash range largely depends on the flash head’s position.
• In the event of over-exposure, use a diffuser adapter, lower the ISO sensitivity setting, or reduce the aperture size.
