Precautions to ensure that the camera is used
safely. Read these precautions thoroughly. Make
sure all details are observed in order to prevent
risks and injury to the user and other people.
Warning Details pertaining to risks that may
result in death or serious injury.
 Do not look at the sun or a bright light source
through the lens or single-lens reflex 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 re.
Caution Details pertaining to risks that may
result in injury.
 Do not leave the camera in locations subject to
high or low temperatures. This may result in the
camera becoming excessively hot or cold, which may
cause burns or other injuries when touched.
 Do not insert your fingers inside the camera.
Failure to observe this may result in injury.
Caution Details pertaining to risks that may
result in damage to property.
 Do not leave the lens in excessive heat such as in a
car in direct sunlight. High temperatures can cause the
lens to malfunction.
Safety Precautions

ENG-3
Handling Precautions
 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, rst 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.
 Please also read any lens related handling precautions
listed in your camera’s instruction manual.

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
ngerprints on them, corrosion or faulty
connections can result. The camera and lens
may not operate properly.
 If the contacts get soiled or have ngerprints on
them, clean them with a soft cloth.
 Attach the lens cap and dust cap when
disconnecting the lens. When attaching the
dust cap, align the lens mount index with the 
index of the dust cap and rotate in a clockwise
direction as shown in the illustration. Follow the
reverse procedure to detach it.
The lens mount has a rubber ring for enhanced
dust- and 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 a cost.
1. Mounting and Detaching the Lens

ENG-7
To zoom, turn the lens’ zoom ring.
Be sure to nish zooming before focusing. Zooming
after focusing can affect the 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 always works, regardless of
the focus mode.
After autofocusing in the AF mode or AF operation
in the ONE SHOT AF mode, focus manually by
pressing the shutter button halfway and turning the
focusing ring (Full-time manual focus).

ENG-8
Innity compensation markDistance index
To compensate for shifting of the innity focus
point that results from changes in temperature,
there is a margin at the innity (∞) position.
The innity position at normal temperature is the
point at which the vertical line of the distance
scale L mark is aligned with the distance index.
For accurate manual focusing of subjects at innity,
look through the viewnder or look at the magnied
image* on the LCD screen while rotating the
focusing ring.
* For cameras with Live View shooting capability.
Infrared Index
The infrared index corrects the focus setting when
using monochrome infrared lm. Focus on the subject
manually, then adjust the distance scale indicated by
the distance index by moving the focusing ring to the
corresponding infrared index mark before shooting.
Some EOS cameras cannot use infrared lm. See
the instructions for your EOS camera.
 The infrared index position is based on a
wavelength of 800 nm.
 The compensation amount differs depending on
the focal length (large at the wide end, small at
the telephoto end). Use the 16 (mm) infrared
index position as a guide when setting the
compensation amount manually.
 Be sure to observe the manufacturer’s
instructions when using infrared lm.
 Use a red lter when you take the picture.

● Attaching
Align the red attachment position mark on the
hood with the red dot on the front of the lens,
and then rotate the hood in the direction of the
arrow until it is rmly attached with the red dot
and stop position mark on the hood aligned.
Button
● Removing
Keep your nger pressed down on the button
located on the side of the hood, and then rotate
the hood in the direction of the arrow until the
attachment position mark on the hood is aligned
with the red dot on the front of the lens to detach
it. The hood can be reverse-mounted on the lens
for storage.
 If the hood is not attached properly, vignetting (darkening of the perimeter of the picture) may occur.
 Grasp and rotate the base of the hood when attaching and detaching it. There are cases in which it may
become deformed if the hood is rotated with it grasped near to the rim.
