ENG-1
Thank you for purchasing a Canon USM lens.
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. It is equipped with an Image
Stabilizer effective for hand-held shooting at
slow shutter speeds.
¡“IS” stands for Image Stabilizer.
¡“USM” stands for Ultrasonic Motor.
Features
1. Aspheric and super UD lens elements for
excellent imaging performance.
2. The Image Stabilizer gives the equivalent
effect of a shutter speed three stops faster.
3. USM for fast, quiet focusing.
4. Great close-ups at 0.45 m/1.5 ft at all focal
lengths.
5. Manual focusing available in autofocusing
mode (ONE SHOT AF).

aSafety Precautions
aSafety 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.
aHandling 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.

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
2. Close-up Photography (Macro Photography)
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.
The lens can focus as close as 0.45 m/1.5 ft for
close-ups (macro photography).
To focus at 0.45 m/1.5 ft, set the lens focus mode
switch to MF. Look through the viewfinder and
move your body forward or back to focus. Take the
shot when the subject is in focus.

ENG-5
3. Setting the Focus Mode 4. 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 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. 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.

5. Image Stabilizer
You can use the image stabilizer in AF or MF mode.
The image stabilizer is particularly
effective for hand-held shots in
the following conditions.
¡Dimly lit scenes, such as at
dusk or indoors
¡
Locations such as art galleries
or theater stages where flash
photography is forbidden
¡Situations in which your
footing is uncertain
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.
¡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.
¡Compared to using a normal non-IS lens,
fewer shots can be taken when you use
an Image Stabilizer lens because more
power is consumed.
¡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.

ENG-8
6. 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.
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.
7. 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.
¡Be sure to observe the manufacturer’s
instructions when using infrared film.
¡Use a red filter also when you take the picture.

ENG-9
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 clockwise until the lens’s 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.
