Warning to prevent lens or camera malfunction
or damage.
Supplementary notes on using the lens and
taking pictures.
1. The Image Stabilizer provides the effect of
having a shutter speed about four stops faster
during normal shooting.*
This function provides optimal image
stabilization depending on shooting conditions
(such as shooting still subjects and following
2. And with the vibration gyro and acceleration
sensor, the image stabilization is highly
effective even for close-up shots.
3. UD lens elements for excellent imaging
4. Ultrasonic motor (USM) for quick and quiet
5. Manual focusing is available after the subject comes
into focus in autofocus mode (ONE SHOT AF).
6. A truly round aperture hole results in a nicer
background blur.
7. A Canon macro flash makes it easy to take
close-up pictures with a flash. The inner
focusing mechanism enables AF photography
while the macro flash is attached.
8. Tight seal structure ensures excellent dust-
proof and drip-proof performance.
* Based on [1/focal length] second.
To prevent blur caused by camera shake during normal
shooting, the shutter speed should be the reciprocal of
the current focal length (1/focal length) or faster.

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

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
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 K index of the dust cap as shown
in the diagram, and turn clockwise. To remove it,
reverse the order.
1. Mounting and Detaching the Lens
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.

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.
2. Setting the Focus
After autofocusing in ONE SHOT AF mode, focus
manually by pressing the shutter button halfway
and turning the focusing ring. (Full-time manual
You can switch the focusing distance range to
one of three settings: FULL (0.3 m/1.0 ft. to
infinity), 0.3 m/1.0 ft. to 0.5 m/1.6 ft., or 0.5 m/1.6
ft. to infinity.
By setting the suitable focusing distance range,
the actual autofocusing time can be shorter.

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 of subjects at
infinity, look through the viewfinder or look at the
magnified image* on the LCD screen while
rotating the focusing ring.
* For cameras with Live View shooting capability.

5. Hood
The ET-73 hood can keep unwanted light out of the lens, and also protects the lens from rain, snow,
and dust.
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.
• Remove the hood when using the macro flash.

6. Picture Taking
Normal Photography
The lens can be used as a medium-telephoto
lens for normal photography such as portraits.
Closeup Photography
Close-up photos up to 1x (life-size) magnification
are possible. The minimum focusing distance of
30 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 14 cm.
For normal close-up shooting, the higher the
magnification, the faster the shutter speed must
be to prevent blur caused by camera shake.
Although it depends on the shooting conditions,
usually the shutter speed must be at least one or
two stops faster than normal.
For a shooting magnification of 0.5x, this lens
provides the effect of a shutter speed faster by
about three stops. For 1x, it will be about two
stops faster.*
* Depending on shooting conditions.
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 check the depth of field, press the camera's
depth-of-field preview button.

7. About Exposure
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
Magnification and Effective f-
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-
• 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.

When you use a handheld exposure meter to set
the exposure, you must take into account the
exposure factor shown in the following table.

8. Image Stabilizer
You can use the image stabilizer in AF or MF mode.
This function provides optimal image stabilization depending on
shooting conditions (such as shooting still subjects and following
The image stabilizer in this lens is
effective for hand-held shots under
the following conditions.
• Close-up shooting.
• 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
• In situations where fast shutter
settings cannot be used.

Image Stabilizer
• The shorter the subject distance from the
camera, the lesser the Image Stabilizer effect
will be.
• 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 may not be fully effective if
you shoot from a violently shaking vehicle or
other transportation.
• 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 IIE/50/50E, REBEL 2000/300, IX, and
D30, the Image Stabilizer will not work during
self-timer operation.
• When shooting a still subject, it compensates for
camera shake in all directions.
• It compensates for vertical camera shake during
following shots in a horizontal direction, and
compensates for horizontal camera shake
during following shots in a vertical direction.
• Using a tripod also stabilizes the image.
However, depending on the kind of tripod and
shooting conditions, sometimes it may be better
to turn off the Image Stabilizer function.
• The stabilizer is equally effective for hand-held
photography and photography with a monopod.
• The image stabilizer function also operates
when the lens is used with an Extension Tube
EF12 ll or EF25 ll.
• Pictures may look distorted after being taken
depending on the camera, but this doesn't affect
• 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.

9.Taking Hand-held Close-ups
Close-up shots are more prone to be affected by
camera shake than with normal shooting. The
Image Stabilizer's corrective effect is therefore
less during close-ups than during normal shooting
even with the same degree of camera shake.
The depth of field also becomes very shallow with
close-ups, and moving forward or back even
slightly will throw off the focus.
When hand-holding the camera for close-up
shooting, minimize camera shake and blurred
focus with the following techniques:
Hold the camera firmly
As shown on the right, hold the camera firmly so
it does not move while shooting.
Use AI Servo AF
For close-up shots, set the camera's AF mode to
AI Servo AF. Using autofocus is recommended.
The AI Servo AF mode can minimize blurred
focus during close-up shooting.
For details, see the camera's instruction manual.
Place both elbows on a steady surface such as a table.
Use your knee to support
an arm holding the
Lean against a steady
object like a wall.
