Thank you for purchasing a Canon product.
Canon’s EF300mm f/2.8L IS USM, EF400mm f/2.8L
IS USM, EF500mm f/4L IS USM and EF600mm
f/4L IS USM are high-performance super-telephoto
lenses, for use with EOS cameras. 
●“IS” stands for Image Stabilizer.
● “USM” stands for Ultrasonic Motor.
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 stand on top of the lens case. You may fall and
injure yourself. 
Do not pile lens cases on top of one another as they
may fall and cause injury.
● Do not leave the lens in excessive heat such as in a
car in direct sunlight.  High temperatures can cause
the lens to malfunction.
Features1. The Image Stabilizer gives the equivalent effect
of a shutter speed two stops* faster.
2. Use of fluorite and UD lens elements giving superior definition.
3. Ultrasonic motor (USM) for fast, quiet autofocus.
4. Manual focusing is available after the subject comes into focus in autofocus mode (ONE SHOT
AF).
5. An AF stop button to pause autofocus whenever desired.
6. Can be used with EF1.4 ×II/EF2 ×II extenders.
7. A focus preset function for advance storage of focusing positions in memory to allow
instantaneous focusing.
8. Tight seal structure ensures excellent dustproof and drip-proof performance.
9. Designed for lighter weight with parts made of magnesium alloy.
*Based on [1/focal length] second. 
Generally, it requires a shutter speed [1/focal length]
second or faster to prevent camera shake.

a Safety 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.

See your camera’s instructions for details on
mounting and detaching the lens.
1. 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
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  
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.
