EF300mm F2.8L IS USM EF400mm F2.
Thank you for purchasing this Canon IS USM lens. 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. They are equipped with an image stabilizer effective for hand-held shooting at slow shutter speeds. ● “IS” stands for Image Stabilizer. ● “USM” stands for Ultrasonic Motor.
a Safety Precautions 1. 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. 2. 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. This device complies with Part 15 of the FCC Rules.

1. 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 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.
2. Setting the Focus Mode AF MF 3. Switching the Focusing Range 2.5m AF 2.5m 6.4m 6.4m MF STABILIZER To shoot in autofocus mode, set the focus mode switch to AF. To use only manual focusing, set the focus mode switch to MF, and focus by turning the focusing ring. The focusing range can be selected by this switch to suit the shooting situation. This can reduce the time needed for autofocusing. Lens Ranges 2.5 m/8.2 ft. – ∞ EF300mm f/2.8L IS USM 2.5 m/8.2 ft. – 6.4 m/21.0 ft. 6.4 m/21.0 ft. – ∞ 3 m/9.
Switching the focusing range 4. AF Stop Button ● Before switching the focusing range, turn the focusing ring to select a focusing distance somewhere within the desired range. ● If you do not set the lens to a focusing distance that is within the selected focusing range, autofocusing may stop when it reaches the range boundary. This is not a fault. If it happens, press the shutter button halfway down again. During autofocus operation, you can press the AF stop button to temporarily pause autofocus.
AF Stop Button ● The AF stop function cannot be used with the EOS EF-M on manual focus cameras. ● On the EOS 630/600, EOS RT, EOS A2/A2E/5 or EOS10S/10, if the AF mode is set to AI SERVO AF and film winding is set for continuous shooting, autofocusing will not resume when you release the AF stop button. To resume autofocusing, release the shutter button and then press it halfway down again.
6. Focus Preset If a particular focusing position is stored in the lens’s memory, the focus can be set instantly to the stored position, even when pictures are being taken of other subjects. This feature can be used in both AF and MF focus modes. < Storing a Focus Position > 1 1 2 FOCUS PRESET FOCUS PRESET SET SET Set the focus preset switch to or . ENG-8 2 STABILIZER MODE STABILIZER MODE Press the shutter button halfway and set the focus to the position you want to store in the lens’s memory.
Focus Preset < Recalling a focus Position > Rotate the focus recall ring right or left and then press the shutter button fully to take the picture. ● Release the shutter button when you turn the focus recall ring. If the AF mode is set to ONE SHOT AF, the exposure setting locks when you press the shutter button halfway. Consequently, the exposure may not be set correctly if you are holding the shutter button halfway down as you turn the focus recall ring.
7. Image Stabilizer You can use the image stabilizer in AF or MF mode. STABILIZER 1 2 STABILIZER MODE 1 2 FOCUS PRESET STABILIZER MODE Set the image stabilizer switch to (on). ● If you are not going to use the image stabilizer function, set the switch to (off). ENG-10 Select the stabilizer mode. ● Select MODE 1 for standard photography. MODE 1 corrects all vibrations no matter whether the camera is being held horizontally, vertically, or at an angle. ● To pan a moving subject, select MODE 2.
8. Tips on Using the Image Stabilizer The image stabilizer is particularly effective for hand-held shots in the following conditions. ● MODE 1 ● MODE 2 (ON) (ON) (OFF) q In semi-darkened areas such as indoors or outdoors at night. w In locations where flash photography is prohibited, such as art museums and theater stages. e In situations where fast shutter settings cannot be used. r In situations where your footing is uncertain. (OFF) q When panning subjects in motion.
Tips on Using the Image Stabilizer ● Set the image stabilizer switch to (off) when you are taking pictures with a tripod. * Even if the image stabilizer switch is set to (on), the IS function does not operate because the electronic circuits in the lens automatically detect that a tripod is being used. However, because electrical power is still being supplied to the image stabilizer unit, the number of available shots is roughly 20% fewer than it would be with the switch set to (off).
Tips on Using the Image Stabilizer ● The image stabilizer function also operates when the lens is used with an EF12 II or EF25 II extension tube. ● If you set the camera’s Custom Function to change the assigned button to operate the AF, the image stabilizer will operate when you press the newly assigned AF button. 9.

10. Using the Tripod Mount Adjusting the Tripod Mount Loosening the orientation lock knob on the tripod mount allows you to turn the lens and camera freely. This is useful when you want to switch the camera between landscape and portrait positions while it is mounted on a tripod. Once you have set the camera to the desired position, tighten the lock knob firmly. Detaching the Tripod Mount (EF300mm f/2.
11. Hood The special hoods that come with all these lenses cut out unwanted light and protect the front of the lens from rain, snow, and dust. To attach the hood, loosen the hood lock knob by turning it counterclockwise. Fit the hood onto the lens’s hood mount, and tighten the lock knob to fix it in place. Use the same procedure, in reverse, to remove the hood. 12. Case When putting the lens into its case, reverse the lens hood, slip it over the lens, and attach the lens cap.
13. Drop-In Filters A 52-series drop-in gelatin filter holder with a glass filter is installed as standard equipment on each lens. The drop-in filter is used fitted with a gelatin filter (sold separately). 14mm 14mm 47mm 47mm To remove the drop-in filter, press in the left and right lock buttons and pull the filter holder straight up out of the slot.

With the EOS-1V/HS, EOS-3, EOS-1Ds Mark II, EOS1Ds, EOS-1D Mark II N, EOS-1D Mark II or EOS-1D cameras, auto-focusing is only effective for the central focusing point. ● When taking pictures on an EOS 5 using an EF1.
