ENG-1
Thank you for purchasing a Canon product.
The Canon EF24-105mm f/4L IS USM lens is a
high-performance standard zoom lens
developed for EOS cameras. It is equipped
with an Image Stabilizer, and covers a wide
range of focal lengths from wide angle to
mid-telephoto.
¡“IS” stands for Image Stabilizer.
¡“USM” stands for Ultrasonic Motor.
Features
1. The Image Stabilizer gives the equivalent
effect of a shutter speed three stops faster.*
2. Aspheric and super UD lens elements for
excellent imaging performance.
3. Ultrasonic motor (USM) for quick and quiet
autofocusing.
4. Manual focusing is available after the subject
comes into focus in autofocus mode (ONE
SHOT AF).
5. A truly round aperture hole results in a nicer
background blur.
6. Tight seal structure ensures excellent dust-
proof and drip-proof performance.
*Based on [1/focal length] second. Generally, it requires
a shutter speed [1/focal length] second or faster to
prevent camera shake.

aSafety Precautions
aSafety 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.
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
against harmful interference in a 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.
•Consult the dealer or an experienced radio/TV technician for
help.
This Class B digital apparatus complies with Canadian ICES-003.

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.

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 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.
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. Image Stabilizer
You can use the image stabilizer in AF or MF mode.
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 flash
photography is prohibited, such as
art museums and theater stages.
¡In situations where your footing is
uncertain.
¡In situations where fast shutter
settings cannot be used.
1Set the STABILIZER
switch to .
¡If you are not going to
use the image stabilizer
function, set the switch to
.
2When you press the
shutter button halfway,
the Image Stabilizer
will start operating.
¡Make sure the image in
the viewfinder is stable,
then press the shutter
button the rest of the way
down to take the picture.

ENG-7
Image Stabilizer
¡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 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 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 might not be fully
effective in the following cases:
• You move the camera for a panned shot.
• You shoot while riding on a bumpy road.
¡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, 30/33/Elan7/7E,
30V/33V/Elan7N/7NE, Elan ll/Elan ll
E/50/50 E, 300/Rebel2000, IX, and D30,
the Image Stabilizer will not work during
self-timer operation.

5. Infinity Compensation 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.
For accurate manual focusing on subjects at
infinity distance, look through the viewfinder while
rotating the focusing ring.
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.
6. Infrared Index
Some EOS cameras cannot use infrared film. See
the instructions for your EOS camera.
¡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 film.
¡Use a red filter also when you take the picture.

The EW-83H 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.
