Thank you for purchasing a Canon USM lens.

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

the dust cap, and turn clockwise. To remove it, reverse the

order.

2. Setting the Focus Mode

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

To use only manual focusing, set the focus mode switch to

MF, and focus by turning the focusing ring.

• Do not touch the focusing ring on the lens during

autofocusing.

Instructions

3. Full-time Manual Focusing

Full-time manual focusing allows you to focus manually even

when autofocus mode is selected.

1) Set the camera to ONE SHOT AF mode and press the

shutter button halfway.

2) Keep the shutter button pressed halfway and turn the

focusing ring to focus manually

4. Aperture Setting

Aperture settings are specified on the camera.

5. Infinity Distance Mark

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

To make sure focus is precise, it is recommended that you

check the focus in the viewfinder before shooting.

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

Use a red filter also when you take the picture.

• Switch the focus mode to MF to turn the focusing ring for

adjustment.

• The position of the infrared indices is based on film usage

with a peak sensitivity of 800 nm and a red filter (such

as Wratten 87). Using black and white infrared film with

a different sensitivity may require a slightly different

setting. Thus, it is recommended to take trial shots with the

focusing ring set slightly to the left and then right of the

appropriate index to find the best position.

• Be sure to observe the manufacturer's instructions when

using infrared film.

7. Filter (sold separately)

The filter screws onto the front of the lens.

❹

• If you need a polarizing filter, use Canon's PL-C polarizing

filter.
