Instructions
Thank you for purchasing a Canon product.
Canon’s EF300mm f/2.8L IS II USM and EF400mm f/2.8L IS II USM are high-performance supertelephoto lenses, for use with EOS cameras.
OO“IS” stands for Image Stabilizer. OO“USM” stands for Ultrasonic Motor.
Features
1.The Image Stabilizer gives the equivalent effect of a shutter speed four stops* faster.
Also, a third Image Stabilizer mode effective for shooting irregularly moving subjects.
2.Use of fluorite lens elements giving superior definition.
3.SWC (Subwavelength Structure Coating) reduces flare and ghosting.
4.Using a fluorine 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 SHOT AF).
7.An AF stop button to pause autofocus whenever desired.
8.A power focus mode enables smooth focus change.
9.A focus preset function for advance storage of focusing positions in memory to allow instantaneous focusing.
10.Circular aperture for producing beautiful softfocus images.
11.Can be used with EF1.4× III/EF2× III extenders.
12.Attachment slot provided for wire-type security lock, located under the cover for the orientation locking knob.
13.Tight seal structure ensures excellent dustproof and drip-proof performance.
14.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.

Safety Precautions
Handling Cautions
OOIf 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.
OODo not leave the lens in excessive heat such as in a car in direct sunlight. High temperatures can cause the lens to malfunction.
Conventions used in this instruction
Warning to prevent lens or camera malfunction or damage.
Supplementary notes on using the lens and taking pictures.
Safety Precautions
OODo 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.
OOWhether 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.
OOWhen the lens is mounted on a camera, be sure to also hold the camera by the lens, including when mounting on a tripod. Only holding by the camera could result in
scratches on the camera body or the lens itself. The lens may also detach from its mount and fall, causing injury.
OODo not use a strap attached to the camera. The mount may break, resulting in the lens falling off and causing injury or in scratches on the camera. Be sure to use the camera with a dedicated strap attached correctly to the strap mount on the lens.
OODo not stand on top of the lens case. You may fall and injure yourself.
OODo not pile lens cases on top of one another as they may fall and cause injury.

1. Mounting and Detaching the Lens
See your camera’s instructions for details on mounting and detaching the lens.
The lens mount has a rubber ring for enhanced dustand 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.
OOAfter detaching the lens, place the lens with the rear end up to prevent the lens surface and contacts from getting scratched.
OOIf the contacts get soiled, scratched, or have fingerprints on them, corrosion or faulty
connections can result. The camera and lens may not operate properly.
OOIf the contacts get soiled or have fingerprints on them, clean them with a soft cloth.
OOIf 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.
Attaching the strap
Thread the end of the strap through the strap mount on the lens and then back through the clasp on the strap. Pull the strap tight and check that there is no slack in the clasp.

2. Setting the Focus Mode 3. Switching the Focusing Distance Range
To shoot in autofocus (AF) mode, set the focus mode switch to AF.
To shoot in manual focus (MF) mode, set the focus mode switch to MF, and focus by turning the focusing ring. The focusing ring always works, regardless of the focus mode.
To shoot in power focus (PF) mode, set the focus mode switch to PF when the focus preset switch (p. 8) is at OFF.
Operating the playback ring enables focus change at a set speed. This is a useful feature for changing focus when shooting movies.
After autofocusing in ONE SHOT AF mode, focus manually by pressing the shutter button halfway and turning the focusing ring. (Full-time manual focus)
You can set the focusing distance range with a switch. By setting a suitable focusing distance range, the actual autofocusing time will be shorter.
