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.
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.
• 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, and turn clockwise. To remove it, reverse the order.
Doing so could result in loss of vision. Looking
This is to
2. Setting the Focus Mode
To shoot in autofocus (AF) mode, set the focus mode switch to AF ❹. 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.
• After autofocusing in ONE SHOT AF mode, focus manually by pressing the shutter button halfway and turning the focusing ring. (Full-time manual focus)
3. Zooming
To zoom, turn the lens’ zoom ring ❺.
• Be sure to finish zooming before focusing. Changing the zoom ring after focusing can affect the focus.
4. Infrared Index
The infrared index corrects the focus setting when using monochrome infrared film. Focus on the subject in MF, then adjust the distance setting by moving the focusing ring to the corresponding infrared index mark
.
• 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.
5. Infinity Compensation Mark
COPY
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 accurate focusing in MF on subjects at infinity distance, look through the viewfinder while rotating the focusing ring ❼.
6. Hood
To attach the hood, align the hood’s attachment position mark with the red dot on the front of the lens, then turn the hood in the direction of the arrow until the lens’s red dot is aligned with the hood’s stop position mark ❽. The hood can be reverse-mounted on the lens for storage.
• Part of the picture may be blocked if the hood is not attached properly.
7. Filters (Sold Separately)
You can attach filters to the filter mounting thread on the front of the lens.
• Use a polarizing Canon filter (77mm).
8. Switching the Focusing Distance Range (EF70­200mm f/2.8L USM Only)
You can set the focusing distance range to 1.5 m/4.9 ft. to infinity or 3m/9.8 ft. to infinity ❾.
• If you use AF from outside the specified focusing distance range, the lens may stop focusing when it reaches the limit of the range. This is not a malfunction. If this occurs, press the shutter button halfway down again.
9. Extenders (Sold Separately: EF70-200mm f/2.8L USM Only)
AF is possible with Extender EF1.4× II/EF2× II.
• The aperture F values and focal lengths when an extender is used are as follows: EF1.4× II: f/4, 98-280mm, EF2× II: f/5.6, 140-400mm
Attach the extender to the lens, and then attach the lens to the camera. To remove it, reverse the order. Errors may occur if you attach the extender to the camera first. When you are using an extender, use the center focusing point for AF. If you use AF with a different focusing point, a focusing error may occur.
10. Using the Tripod Mount (EF70-200mm f/2.8L USM Only)
By loosening the orientation locking knob on the tripod mount you can rotate the camera to set the image for any vertical or horizontal position.
Detaching the Tripod Mount
First remove the lens from the camera and then remove the tripod mount from the lens as shown below. To attach the tripod mount, reverse the procedure.
1) Loosen the orientation locking knob
2) Align the red mark on the tripod mount with the lens mount
index ⓫.
3) Slide off the tripod collar away from the rear of the lens ⓬.
