Safety Precautions

Handling Cautions

O O

O O

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.

O O

O O

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.

When the lens is mounted on a camera, be sure to also hold the camera by the lens, including when mounting on a tripod. Only holding by the camera could result in scratches on the camera body or the lens itself. The lens may also detach from its mount and fall, causing injury.

Do not use a strap attached to the camera. The mount may break, resulting in the lens falling off and causing injury or in scratches on the camera. Be sure to use the camera with a dedicated strap attached correctly to the strap mount on the lens.

Do not stand on top of the lens case. You may fall and injure yourself.

Do not pile lens cases on top of one another as they may fall and cause injury.

1. Mounting and Detaching the Lens

See your camera’s instructions for details on mounting and detaching the lens.

The lens mount has a rubber ring for enhanced dust- and water-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.

Attaching the strap

O O

O O

O O

O O

After detaching the lens, place the lens with the rear end up to prevent the lens surface and 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.

Thread the end of the strap through the strap mount on the lens and then back through the clasp on the strap. Pull the strap tight and check that there is no slack in the clasp.

Using the playback ring enables smooth focus change.

This is a useful feature for changing focus when shooting movies.

With the focus preset switch set to OFF, set the focus mode switch to PF.

Rotate the playback ring to change the focus.

When the playback ring is rotated in a certain direction, focus changes in the same direction as when the focusing ring is rotated.

You can make a 2-step change in focus shift speed depending on the angle that the playback ring is rotated to.

ENG-10

7. Image Stabilizer

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

Set the STABILIZER switch to ON.

O O

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

Select the stabilizer mode.

O O

O O

MODE 1: Corrects vibrations in all directions. It is mainly effective for shooting still subjects.

MODE 2: Corrects vertical camera shake during following shots in a horizontal

O O direction, and corrects horizontal camera shake during following shots in a vertical direction.

MODE 3: Corrects vibration only during exposure. During panning shots, corrects vibration during exposure only in one direction the same as MODE 2.

Press the shutter button down halfway to enable stabilization (MODE 1 and

2).

O O

Make sure the image in the viewfinder is stable, then

O O press the shutter button the rest of the way down to take the picture.

Tips on Using the Image Stabilizer

O O

O O

O O

O O

O O

O O

The Image Stabilizer cannot compensate for a blurred shot caused by a subject that moved.

Set the STABILIZER switch to OFF when you are taking pictures using the Bulb setting (long exposures). If the STABILIZER switch is set to

ON, the image stabilizer function may introduce errors.

The Image Stabilizer might not be fully effective in the following cases:

• You shoot from a violently moving vehicle.

• You move the camera dramatically for a panning shot in Mode 1.

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, ELAN 7E/ELAN

7/30/33, ELAN 7NE/ELAN 7N/30V/33V, ELAN II/

ELAN II E/50/50E, REBEL 2000/300, IX, IX Lite/

IX7, and D30, the Image Stabilizer will not work during self-timer operation.

O O

Using a tripod also stabilizes the image.

However, depending on the kind of tripod and shooting conditions, sometimes it may be better

O O to turn off the Image Stabilizer function.

The stabilizer is equally effective for handheld photography and photography with a monopod. The Image Stabilizer effect may be reduced, however, depending on the shooting environment.

O O

The Image Stabilizer also operates when the

O O lens is used with extension tube EF12 II or EF25

II or the extender EF1.4× III or EF2× III.

Depending on the camera there may be image

O O shake, such as after releasing the shutter.

However, this does not 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.

Infinity compensation mark

10. Hood

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 focusing in MF on subjects at infinity distance, look through the viewfinder while rotating the focusing ring.

The special hoods that come with all these lenses cut out unwanted light and protect the front of the lens from rain, snow, and dust.

To attach the hood, loosen the hood lock knob by turning it counterclockwise. Fit the hood onto the lens’s hood mount, and tighten the lock knob to fix it in place. Use the same procedure, in reverse, to remove the hood.
