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.

Conventions used in this instruction

• Warning to prevent lens or camera malfunction or damage.
• Supplementary notes on using the lens and taking pictures.

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.

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.
• 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.

Mounting and Detaching the Lens

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 a 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.

Setting the Focus Mode

• 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 always works, regardless of the focus mode.
• After autofocusing in ONE SHOT AF mode, focus manually by pressing the shutter button halfway and turning the focusing ring. (Full-time manual focus)

Switching the Focusing Distance Range

• You can choose the focusing distance range with a switch. By setting a suitable focusing distance range, actual autofocusing time can be shorter.
• EF135mm f/2L USM :

1. 0.9 m / 3.0 ft. –
2. w 1.6 m / 5.2 ft. – ∞

• EF200mm f/2.8L II USM :

1. 1.5 m / 4.9 ft. –
2. w 3.5 m / 11.5 ft. – ∞

EF300mm f/4L USM :

1. 2.5 m / 8.2 ft. –
2. w 6 m / 19.7 ft. – ∞

EF400mm f/5.6L USM :

1. 3.5 m / 11.5 ft. –
2. w 8.5 m / 27.9 ft. – ∞

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.

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 L mark is aligned with the distance indicator on the distance scale.
• For an accurate manual focusing on subjects at infinity distance, look through the viewfinder while rotating the focusing ring.

Infrared Index

• (EF200mm f/2.8L II USM
• EF300mm f/4L USM
• EF400mm f/5.6L USM)
• 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.
• 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.

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 F value.
• The depth-of-field scale is an approximate indicator.

Using the Tripod Mount

• (EF200mm f/2.8L II USM
• EF300mm f/4L USM
• EF400mm f/5.6L USM)

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 be used with the A II (B) tripod mount ring, sold separately.

Detaching

• Use the following procedures to remove and attach the tripod mount.

1. Turn the locking knob counterclockwise until it becomes loose (about 3 turns), and pull the knob in the direction of the arrow to release the collar.
2. With the collar open, remove the tripod mount.
3. 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 move the foot.
• The tripod mount can be attached to or detached from the lens while the lens is attached to the camera.

Hood

The lens hood can reduce unwanted reflections and also protects the front of the lens from rain, snow, dust, and other substances.

• 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 be reverse-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 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.

Filters (Sold separately)

• You can attach filters to the filter mounting thread on the front of the lens.
• If you need a polarizing filter, use the Canon Circular Polarizing Filter.
• To adjust the polarizing filter, first remove or store the lens hood.
