Instruction  
a Safety Precautions  
This device complies with Part 15 of the FCC Rules. Operation is  
subject to the following two conditions: (1) This device may not  
cause harmful interference, and (2) this device must accept any  
interference received, including interference that may cause  
undesired operation.  
Do not make any changes or modifications to the equipment  
unless otherwise specified in the instructions. If such changes or  
modifications should be made, you could be required to stop  
operation of the equipment.  
This equipment has been tested and found to comply with the  
limits for a class B digital device, pursuant to part 15 of the FCC  
Rules. These limits are designed to provide reasonable protection  
againharmful interference in a residential installation. This  
ipmnt generates, uses and can radiate radio frequency  
eergy and, if not installed and used in accordance with the  
instructions, may cause harmful interference to radio  
communications.  
However, there is no guarantee that interference will not occur in  
a particular installation. If this equipment does cause harmful  
interference to radio or television reception, which can be  
determined by turning the equipment off and on, the user is  
encouraged to try to correct the interference by one or more of  
the following measures:  
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.  
• Reorient or relocate the receiving antenna.  
• Increase the separation between the equipment and receiver.  
• Consult the dealer or an experienced radio/TV technician for  
help.  
This Class B digital apparatus complies with Canadian ICES-003.

Detaching the Lens  
See your camera’s instructions for details on  
mounting and detaching the lens.  
To shoot in autofocus (AF) mode, set the focus  
ode 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 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

from rain, snow, and dust.  
Attach and align the hood to the hood mount on  
the front of the lens, and turn the hood as shown  
by the arrow to secure it.  
The hood can be reverse-mounted on the lens  
for storage.  
If you autofocus outside the set focusing distance  
range, the lens may stop focusing at the start of  
the focusing range; however, this is not a  
malfunction. Press the shutter release button  
halfway again.  
• 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.  
• Remove the hood when using the macro flash.  
ENG-5  
5. Picture Taking  
3. Focus the subject.  
Normal Photography  
The lens can be used as a medium-telephoto  
lens for normal photography such as portraits.  
While looking through the viewfinder, move the  
camera forward or back to find the point of  
focus.  
Closeup Photography  
4. Touch up the focus.  
Turn the focusing ring for fine focusing.  
Close-up photos up to 1x (life-size) magnification  
are possible. The minimum focusing distance of  
31 cm is the distance from the subject to the  
focal plane. The working distance from the front  
of the lens to the subject is about 15 cm.  
When focusing, you can give priority to framing  
or to magnification.  
Since macro shots have a very shallow depth of  
field, focus carefully to obtain proper sharpness.  
• The magnification refers to the ratio between the  
subject’s size and the corresponding image size  
on the focal plane. On the distance index, it is  
indicated as 1:x.  
To prevent camera shake, using a Remote  
Switch (both sold separately) and tripod is  
recommended.  
[Framing Priority]  
While looking through the viewfinder and framing  
the subject, focus with the AF or MF mode.  
To check the depth of field, press the camera's  
depth-of-field preview button.  
[Magnification Priority]  
1. Set the lens' focus mode switch to MF.  
2. Set the magnification.  
While referring to the magnification scale on  
the lens, turn the focusing ring to the desired  
magnification.  
ENG-6  
6. About Exposure  
When you use a handheld exposure meter to set  
the exposure, you must take into account the  
exposure factor shown in the following table.  
Setting the Exposure  
When taking photographs using TTL metering,  
no exposure compensation is necessary to meter  
the light coming through the lens.  
With TTL metering, AE (autoexposure) is  
possible at all focusing distances. Just set the  
desired picture-taking mode, then check the  
shutter speed and aperture before taking the  
picture.

Magnification and Effective f-  
number  
• The correct exposure for a close-up shot largely  
depends on the subject. Therefore, try to bracket  
the exposure for the same subject.  
• Using aperture-priority AE (Av) or Manual (M)  
picture-taking modes are recommended for  
macro photography as it is easy to adjust depth  
of field and exposure in these modes.  
The aperture displayed by the camera assumes  
that the focus is set to infinity. The actual  
aperture (effective f-number) becomes darker  
(effective f-number increases) at closer focusing  
distances (magnification increases). This does  
not cause exposure problems for normal picture-  
taking. However, for closeup photography, you  
cannot ignore the change in the effective f-  
number.  
If your eye will not be covering the eyepiece when  
the picture is taken (with remote control operation,  
etc.), use the eyepiece shutter or eyepiece cover.  
This prevents stray light from entering the  
eyepiece and throwing off the proper exposure.

• When switching to vertical shooting, rotate the

the camera in the opposite direction will have  
the grip bump into the tripod mount.  
For accurate manual focusing on subjects at  
infinity distance, look through the viewfinder while  
rotating the focusing ring.  
• Before attaching or detaching the lens, set the  
tripod mount back to its normal position  
(horizontal shooting position). Otherwise, the  
tripod mount may bump into the camera grip or  
pentaprism and prevent the lens from being  
attached to or detached from the camera.  
• If the EOS camera has a built-in flash, the  
pentaprism may prevent the tripod mount from  
being rotated to the top of the lens.
