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).

6. A truly round aperture hole results in a nicer
background blur.

7. Tight seal structure ensures excellent dust-
proof and drip-proof performance.

a Safety Precautions

a Safety 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.

a 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.

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.

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.
