Instructions

Thank you for purchasing a Canon product.

Safety Precautions

1. 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.

2. 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.

1. Mounting and Detaching the Lens

See your camera's instructions for details on mounting and

detaching the lens.

• 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, and turn clockwise. To remove it, reverse the order.

2. Setting the Focus Mode

To shoot in autofocus (AF) mode, set the focus mode switch to AF

To shoot in manual focus (MF) mode, 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. Infrared Index

The infrared index corrects the focus setting when using

monochrome infrared film.

Focus on the subject in MF, then adjust the distance setting by

moving the focusing ring to the corresponding infrared index mark

❻

• The infrared index position is based on a wavelength of 800 nm.

• Be sure to observe the manufacturer's instructions when using

infrared film.

• Use a red filter also when you take the picture.
