Conventions used in this instruction

Warning to prevent lens or camera malfunction or damage.

Supplementary notes on using the lens and taking pictures.

Features

1. The Image Stabilizer gives the equivalent effect of a shutter speed three stops faster.*
2. Aspheric and super UD lens elements for excellent imaging performance.
3. Ultrasonic motor (USM) for quick and quiet autofocusing.
4. Manual focusing is available after the subject comes into focus in autofocus mode (ONE SHOT AF).
5. A truly round aperture hole results in a nicer background blur.
6. Tight seal structure ensures excellent dust-proof and drip-proof performance.

* Based on [1/focal length] second. Generally, it requires a shutter speed [1/focal length] second or faster to prevent camera shake.

a Safety Precautions

a Safety Precautions

• Do not look at the sun or a bright light source through the lens or camera. Doing so could result in loss of vision. Looking at the sun directly through the lens is especially hazardous.
• Whether it is attached to the camera or not, do not leave the lens under the sun without the lens cap attached. This is to prevent the lens from concentrating the sun's rays, which could cause a fire.

Handling Cautions

• If the lens is taken from a cold environment into a warm one, condensation may develop on the lens surface and internal parts. To prevent condensation in this case, first put the lens into an airtight plastic bag before taking it from a cold to warm environment. Then take out the lens after it has warmed gradually. Do the same when taking the lens from a warm environment into a cold one.
• Do not leave the lens in excessive heat such as in a car in direct sunlight. High temperatures can cause the lens to malfunction.

• After detaching the lens, place the lens with the rear end up to prevent the lens surface and electrical contacts from getting scratched.
• If the contacts get soiled, scratched, or have fingerprints on them, corrosion or faulty connections can result. The camera and lens may not operate properly.
• If the contacts get soiled or have fingerprints on them, clean them with a soft cloth.
• If you remove the lens, cover it with the dust cap. To attach it properly, align the lens mount index and the index of the dust cap as shown in the diagram, and turn clockwise. To remove it, reverse the order.

The lens mount has a rubber ring for enhanced water- and dust-resistance. The rubber ring may cause slight abrasions around the camera's lens mount, but this will not cause any problems. If the rubber ring becomes worn, it is replaceable by a Canon Service Center at cost.

2. 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. The focusing ring always works, regardless of the focus mode.

After autofocusing in ONE SHOT AF mode, focus manually by pressing the shutter button halfway and turning the focusing ring. (Full-time manual focus)

3. Zooming

To zoom, turn the lens' zoom ring.

Be sure to finish zooming before focusing. Changing the zoom ring after focusing can affect the focus.

4. Image Stabilizer

You can use the image stabilizer in AF or MF mode.

STABILIZER ON OFF

1 Set the STABILIZER switch to ON

- If you are not going to use the image stabilizer function, set the switch to OFF.

The image stabilizer in this lens is effective for hand-held shots under the following conditions.

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

ENG-6

Image Stabilizer

• The Image Stabilizer cannot compensate for a blurred shot caused by a subject that moved.
• Set the STABILIZER switch to when you are taking pictures using the Bulb setting (long exposures). If the STABILIZER switch is set to the image stabilizer function may introduce errors.
• The Image Stabilizer might not be fully effective in the following cases:
• You move the camera for a panned shot.
• You shoot while riding on a bumpy road.
• The Image Stabilizer consumes more power than normal shooting, so fewer shots can be taken if you use the function.
• The image stabilizer operates for about two seconds even when your finger is off the shutter button. Do not remove the lens while the stabilizer is in operation. This will cause a malfunction.

• With the EOS-1V/HS, 3, 30/33/Elan7/7E, 30V/33V/Elan7N/7NE, Elan II/Elan II E/50/50 E, 300/Rebel2000, IX, and D30, the Image Stabilizer will not work during self-timer operation.

• When you use a tripod, the Image Stabilizer should be turned off to save battery power.
• The stabilizer is equally effective for handheld photography and photography with a monopod.
• The image stabilizer function also operates when the lens is used with an Extension Tube EF12 II or EF25 II.
  ● Pictures may look distorted after being taken depending on the camera, but this doesn't affect shooting.
• If you set the camera's Custom Function to change the assigned button to operate the AF, the Image Stabilizer will operate when you press the newly assigned AF button.

5. Infinity Compensation Mark

Infinity compensation mark 10 20 5 3 5 ft m Distance index

To compensate for shifting of the infinity focus point that results from changes in temperature. The infinity position at normal temperature is the point at which the vertical line of the L mark is aligned with the distance indicator on the distance scale.

For accurate manual focusing on subjects at infinity distance, look through the viewfinder while rotating the focusing ring.

6. Infrared Index

The infrared index corrects the focus setting when using monochrome infrared film. Focus on the subject manually, then adjust the distance setting by moving the focusing ring to the corresponding infrared index mark.

Some EOS cameras cannot use infrared film. See the instructions for your EOS camera.

• The infrared index position is based on a wavelength of 800 nm.
• The compensation amount differs depending on the focal length. Use the indicated focal length as a guide when setting the compensation amount.
• Be sure to observe the manufacturer's instructions when using infrared film.
• Use a red filter also when you take the picture.

To attach the hood, align the hood's attachment position mark with the red dot on the front of the lens, then turn the hood as shown by the arrow until the lens' red dot is aligned with the hood's stop position mark.

The hood can be reverse-mounted on the lens for storage.

• Part of the picture may be blocked if the hood is not attached properly.
• When attaching or detaching the hood, grasp the base of the hood to turn it. To prevent deformation, do not grasp the rim of the hood to turn it.

8. Filters (Sold separately)

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

• Only one filter may be attached.
• If you need a polarizing filter, use the Canon Circular Polarizing Filter (77mm).
• To adjust the polarizing filter, first remove the lens hood.

9. Extension Tubes (Sold separately)

You can attach Extension Tube EF12 II or EF25 II for magnified shots. The shooting distance and magnification are shown below.
