length is set to 400 mm and when used with the
EOS-1D X).
Also, a third Image Stabilizer mode effective for
shooting irregularly moving subjects.
2. Use of uorite and Super UD lens elements
giving superior denition.
3. ASC (Air Sphere Coating) reduces are and
ghosting.
4. Using a uorine coating on the foremost and
rearmost lens surfaces allows adhered dirt to be
removed more easily than before.
5. Ultrasonic motor (USM) for fast, quiet autofocus.
6. Manual focusing is available after the subject
comes into focus in autofocus mode (ONE

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.
When the lens is mounted on a camera, it is
recommended that you also hold the camera by the
lens, including when mounting it on a tripod.
Usage Precautions
When using this lens, please check the Canon website
for the latest camera rmware. If the camera’s rmware
is not the latest version, be sure to update to the latest
rmware.
For details on updating rmware, please check the
Canon website.
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.
Do not point the lens or camera at the sun or
photograph it. This is because the lens concentrates
the sun’s rays even when the sun is outside the image
area or when shooting with backlight, which could
cause malfunction or fire.
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.

1. Mounting and Detaching the Lens
COPY
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
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.
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.
