Thank you for purchasing a Canon product.
Canon’s EF16-35mm f/4L IS USM is a high-
performance ultra-wide angle zoom lens, for use
with EOS cameras. The lens is installed with an
Image Stabilizer.
 “IS” stands for Image Stabilizer.
 “USM” stands for Ultrasonic Motor.
Features
1. Equipped with an Image Stabilizer that provides
an image stabilization effect equivalent to a
shutter speed 4 stops* faster (at 35 mm, when
used with the EOS-1D X).
This function provides optimal image
stabilization depending on shooting conditions
(such as shooting still subjects and following
shots).
2. Use of UD and aspherical lens elements giving
superior denition.
3. Using a uorine coating on the foremost and
rearmost lens surfaces allows adhered dirt to be
removed more easily than before.
4. Ultrasonic motor (USM) for fast, quiet autofocus.
5. Manual focusing is available after the subject
comes into focus in autofocus mode (ONE
SHOT AF).
6. Circular aperture for producing beautiful
softfocus images.
7. Tight seal structure ensures excellent dustproof
and drip-proof performance.
ySince the front element of this lens moves when
zooming, you need to attach a Canon PROTECT
lter sold separately for adequate dust-and water-
resistant performance. Without a lter, the lens is
not dust or water resistant.
* Image stabilization performance based on CIPA
(Camera & Imaging Products Association) Standards.

Safety Precautions
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 re.
Conventions used in this instruction
Warning to prevent lens or camera malfunction
or damage.
Supplementary notes on using the lens and
taking pictures.
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, rst 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.

residential installation. This equipment generates, uses and
can radiate radio frequency energy 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:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and
receiver.
• Connect the equipment into an outlet on a circuit different
from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician
for help.

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.
 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
ngerprints on them, corrosion or faulty
connections can result. The camera and lens
may not operate properly.
 If the contacts get soiled or have ngerprints 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.

2. Setting the Focus Mode 3. Zooming
After autofocusing in ONE SHOT AF mode, focus
manually by pressing the shutter button halfway
and turning the focusing ring. (Full-time manual
focus)
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.
To zoom, rotate the zoom ring.
Be sure to nish zooming before focusing. Zooming
after focusing can affect the focus.

4. Innity Compensation
Mark
For accurate manual focusing of subjects at innity,
look through the viewnder or look at the magnied
image* on the LCD screen while rotating the
focusing ring.
To compensate for shifting of the innity focus
point that results from changes in temperature.
The innity position at normal temperature is the
point at which the vertical line of the distance
scale L mark is aligned with the distance index.
Distance index
Innity compensation
mark
* For cameras with Live View shooting capability.
5. Infrared Index
 The infrared index position is based on a
wavelength of 800 nm.
 The compensation amount differs depending on
the focal length. Use the indicated focal length
as a guide when setting the compensation
amount.
 Be sure to observe the manufacturer’s
instructions when using infrared lm.
 Use a red lter when you take the picture.
Some EOS cameras cannot use infrared lm. See
the instructions for your EOS camera.
The infrared index corrects the focus setting
when using monochrome infrared lm. Focus on
the subject manually, then adjust the distance
setting by moving the focusing ring to the
corresponding infrared index mark.

6. 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
shots).
OFF
ON
The image stabilizer in this lens is
effective for hand-held shots under the
following conditions.
 In semi-darkened areas such as
indoors or outdoors at night.
 In locations where ash
photography is prohibited, such as
art museums and theater stages.
 In situations where your footing is
uncertain.
 When panning subjects in motion.
 In situations where fast shutter
settings cannot be used.
2 When you press the
shutter button halfway, the
Image Stabilizer will start
operating.
 Make sure the image in the
viewnder is stable, then
press the shutter button the
rest of the way down to take
the picture.
1 Set the STABILIZER
switch to ON.
 If you are not going to use the
image stabilizer function, set
the switch to OFF.

 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.
 When you use a tripod, the Image Stabilizer
should be turned off to save battery power.
 The stabilizer is equally effective for hand-
held photography and photography with a
monopod. The Image Stabilizer effect may be
reduced, however, depending on the shooting
environment.
 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
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.
 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 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, resulting in fewer shots and a
shorter movie shooting time.
 The image stabilizer operates for about two
seconds even when your nger 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.
