ENG-1
Thank you for purchasing a Canon product.
The Canon EF135mm f/2L USM, the EF200mm
f/2.8L II USM, the EF300mm f/4L USM, and the
EF400mm f/5.6L USM are high-performance
telephoto lenses designed for EOS cameras.
¡“USM” stands for Ultrasonic Motor.
Features
1. UD lens elements (in the EF135mm f/2L
USM, the EF200mm f/2.8L II USM, the
EF300mm f/4L USM, and the EF400mm
f/5.6L USM) and super UD lens elements (in
the EF400mm f/5.6L USM) for excellent
imaging performance.
2. Ultrasonic motor (USM) for quick and quiet
autofocusing.
3. Manual focusing is available after the subject
comes into focus in autofocus mode (ONE
SHOT AF).
4. The lens is compatible with Extender EF1.4X
ll and EF2X ll.

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 havefingerprints on
them, clean them with asoft cloth.
¡If you removethe 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 removeit,
reverse the order.
1. Mounting and Detaching the Lens 2. Setting the Focus Mode
After autofocusing in ONE SHOTAFmode, 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 alwaysworks,
regardless of the focus mode.

4. 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 Lmark 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.

3. Switching the Focusing Distance Range
You can choose the focusing distance range with
aswitch. By setting asuitable focusing distance
range, actual autofocusing time can beshorter.
¡EF135mm f/2L USM :
q0.9m/ 3.0 ft.–∞w1.6m/ 5.2ft.–∞
¡EF200mm f/2.8L II USM :
q1.5m/ 4.9ft.–∞w3.5m/ 11.5ft.–∞
¡EF300mm f/4L USM :
q2.5m/ 8.2ft.–∞w6m/ 19.7ft.–∞
¡EF400mm f/5.6L USM :
q3.5m/ 11.5ft.–∞w8.5m/ 27.9ft.–∞
If you autofocus outside the set focusing distance
range, the lens may stop focusing at the start of
the focusing range;however, this is not a
malfunction.Press the shutter release button
halfway again.

ENG-6
6. Depth-of-Field Scale
The depth of field is the distance in front of and
behind the plane of focus on the subject that
appears sharp.The depth of field is indicated by
the area between the depth-of-field scale lines
below the distance scale.
The number on the scale is the Fvalue.
The depth-of-field scale is an approximate
indicator.
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.
5. Infrared Index
(EF200mm f/2.8L II USM • EF300mm f/4L
USM • EF400mm f/5.6L USM)
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.
¡Besure to observethe manufacturer’s
instructions when using infrared film.
¡Use ared filter also when you takethe picture.

ENG-7
Adjusting the Revolving Mount
You can loosen the orientation lock-knob on the tripod mount to allow it to rotate as needed to fit a
particular camera model for switching between vertical and horizontal positions.
The EF200mm f/2.8L II USM lens can beused with the A II (B)tripod mount ring, sold separately.
Detaching
Use the following procedures to removeand attach the tripod mount.
Tu r n the locking knob
counterclockwise until it
becomes loose (about 3turns),
and pull the knob in the direction
of the arrow to release the collar.
With the collar open,
removethe tripod mount.
To install, while pulling the
locking knob,bring the collar
to the original position, and
tighten the locking knob
securely.
If the foot of the tripod mount overlaps the switch, loosen the orientation locking knob on the tripod mount to
movethe foot.
7. Using the Tripod Mount (EF200mm f/2.8L II USM • EF300mm f/4L USM • EF400mm f/5.6L USM)
The tripod mount can beattached to or detached from the lens while the lens is attached to the camera.

ENG-8
8. Hood
EF135mm f/2L USM • EF200mm f/2.8L II USM
Attach and align the hood to the hood mount on
the front of the lens, and turn the hood as shown
by the arrow to secure it.
The hood can bereverse-mounted on the lens
for storage.
EF300mm f/4L USM
Bring the hood out from the end of the lens until
it stops.For storage, reverse the procedure.
EF400mm f/5.6L USM
Bring the hood out from the end of the lens until
it stops and turn in the direction of the arrow.For
storage, reverse the procedure.
EF135mm f/2L USM • EF200mm f/2.8L II USM
¡Part of the picture may beblocked 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.
The lens hood can reduce unwanted reflections and also protects the front of the lens from rain,
snow, dust, and other substances.

ENG-9
9. Filters (Sold separately)
You can attach filters to the filter mounting thread
on the front of the lens.
¡If you need apolarizing filter, use the Canon
Circular Polarizing Filter.
¡To adjust the polarizing filter, first removeor
store the lens hood.
10. Close-up Lenses
(Sold separately)
Attaching a500DClose-up Lens enables close-
up photography.
The magnification will beas follows:
¡EF135mm f/2L USM (72mm)
0.48× – 0.27×
