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.
 Do not point the lens or camera at the sun or
photograph it. This is because the lens concentrates
the sun’s rays even when the sun is outside the image
area or when shooting with backlight, which could
cause malfunction or fire.
 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.
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.
General Precautions

ENG-4
Shooting Precautions
This lens uses Nano USM as the drive unit for the focus lens (the lens that aligns the focus).
The motor also controls the focus lens during zooming.
1. When the camera is OFF
The motor does not operate while the camera is OFF or when the camera is OFF due to the use of the auto
power off function. Therefore, users must be aware of the following points.
 Manual focus adjustments are not possible.
 During zooming, delayed focus will occur.
2. When the lens is in sleep mode
If not operated for a certain period of time, this lens will enter sleep mode in order to save power. Sleep mode
differs from when the camera is OFF due to the use of the auto power off function.
In this state, the motor will not operate even if the camera is ON. Therefore, users must be aware of the
following points.
 Manual focus adjustments are not possible.
 During zooming, delayed focus will occur.
 To exit sleep mode, press the shutter button halfway.
General Precautions

ENG-5
When using the lens with lm single-lens reex camera
 The drive speed of the focus lens will be slower than when the lens is used with a digital camera.
 Images will appear out of focus while the camera’s internal ash is charging or when zooming during
exposure for still images.
 Even when the camera in <ON>, images may appear out of focus when zooming. If this occurs, press the
shutter button halfway while zooming.
 After focusing in AF mode or AF operation in the ONE SHOT AF mode and zooming by holding the shutter
button halfway, the camera may indicate that the AF mode has been changed to manual focus (MF) mode.
 During continuous shooting, zooming may slow down shooting speed.
 There are some cases when users must wait a few seconds after zooming before the autofocus (AF) will
function.
 When using the lens with lm single-lens reex camera other than the EOS-1V/HS, information may not be
displayed on the lens information display (p.13-17) even when pressing the shutter button down halfway or all
the way, or when pressing the display mode select button.
 When using the lens with certain lm single-lens reex cameras, displaying information on the lens

 Quickly rotating the focusing ring may result in
delayed focus.
 Manual focus adjustments are not possible when
the camera is OFF.
3. Setting the Focus Mode

ENG-10
The zoom ring can be xed to keep the lens at the shortest point. This function is convenient for
carrying a camera on a strap because it prevents the lens from extending.
1 Rotate the zoom ring to the
widest position (70 mm).
2 Slide the zoom ring lock
lever in the direction
indicated by the arrow.
 To release the zoom ring, slide
the zoom ring lock lever in the
direction opposite to the arrow.
The zoom ring cannot be xed in place at any position other than the
widest position.
4. Fixing the Zoom Ring

ENG-11
You can use the image stabilizer in AF or MF
mode.
This function provides optimal image stabilization
depending on shooting conditions (such as
shooting still subjects and following shots).
1 Set the STABILIZER switch to <ON>.
 If you are not going to use the image stabilizer
function, set the switch to <OFF>.
2 When you press the shutter button halfway,
the Image Stabilizer will start operating.
 Make sure the image in the viewnder is stable,
then press the shutter button the rest of the way
down to take the picture.
<OFF>
<ON>
The image stabilizer in this lens is effective for hand-held
shots under the following conditions.
 In semi-darkened areas such as indoors or outdoors at
night.
 In locations where ash photography is prohibited, such
as art museums and theater stages.
 In situations where your footing is uncertain.
 When panning subjects in motion.
 In situations where fast shutter settings cannot be used.
5. Image Stabilizer

ENG-12
Image Stabilizer
 The Image Stabilizer cannot compensate for a
blurred shot caused by a subject that moved.
 Set the STABILIZER switch to <OFF> when
you are taking pictures using the Bulb setting
(long exposures). If the STABILIZER switch is
set to <ON>, the image stabilizer function may
introduce errors.
 The Image Stabilizer may not be fully effective
if you shoot from a violently shaking vehicle or
other transportation.
 The Image Stabilizer consumes more power
than normal shooting, resulting in fewer shots
and a shorter movie shooting time.
 The image stabilizer operates for about two
seconds even when your nger is off the
shutter button. Do not remove the lens while
the stabilizer is in operation. This will cause a
malfunction.
 With the EOS-1V/HS, 3, ELAN 7E/ELAN
7/30/33, ELAN 7NE/ELAN 7N/30V/33V, ELAN II/
ELAN II E/50/50E, REBEL 2000/300, IX, IX Lite/
IX7, and D30, the Image Stabilizer will not work
during self-timer operation.
 Using a tripod also stabilizes the image.
However, depending on the kind of tripod and
shooting conditions, sometimes it may be better
to turn off the Image Stabilizer function.
 Even with a monopod, the Image Stabilizer will
be as effective as during hand-held shooting.
However, depending on the shooting conditions,
there are cases in which the Image Stabilizer
effect may be less effective.
 The image stabilizer function also operates when
the lens is used with an Extension Tube EF12 II
or EF25 II.
 Depending on the camera there may be image
shake, such as after releasing the shutter.
However, this does not affect shooting.
 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.

ENG-13
6. Lens Information Display
The lens information display allows the user
to select either “Focus distance,” “Focal length
indicator,” or “Shake amount” for the display

are operating.
 When the lens information display is ON, more
battery power is used compared to when it is
OFF which results in a lower number of images
which can be taken and a decrease in the
amount of time for movie shooting.
 It is not possible to adjust the backlight or display
density of the lens information display.

ENG-14
■ Display mode selection
You can switch from one display mode to
another when the display in ON by pressing the

Lens Information Display

ENG-15
 The focusing distance display and focal length
display are only to serve as guides.
 When using the lens with a 35 mm full-format
camera and there is a difference between the
information displayed on the lens information
screen and the zoom ring indication, please
follow the zoom ring indication.
 35 mm format conversion is not possible in the
following cases:
• When using the lens with either a EOS 5DS
or 5DS R camera which is set to 1.3x or 1.6x
crop shooting.
• When using the lens with any of the following
cameras: EOS D6000, EOS D2000, EOS DCS
1, and EOS DCS 3
• When focal length information is recorded in
image data (Exif data)
(3) Camera shake amount display mode
This mode is used to display the amount of
vertical and horizontal shake the camera and
lens are experiencing.
 The camera shake amount display is to only
serve as a guide. Even if no shake is indicated, it
does not guarantee that images will be in focus.
 The camera shake amount display uses
information from the sensor which activates the
Image Stabilizer. However, it does not indicate
the effectiveness of the Image Stabilizer.
 Since the lens information display is located on
the lens, it is not possible to view the camera
shake amount information while using the
camera’s viewnder or LCD monitor. Therefore,
please use it as a guide to check how to hold the
camera and how to press the shutter button in
order to reduce camera shake.

Lens Information Display

ENG-18
See “6. Lens Information Display” and switch
the display mode to “Focusing distance display
mode.”
Distance index
Innity compensation mark
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.
* When using the lens with cameras capable of Live
View shooting, the innity position can be checked by
magnifying the image.
See “6. Lens Information Display” and switch
the display mode to “Focusing distance display
mode.”
The depth of eld is the distance in front of and
behind the plane of focus on the subject that
appears sharp. The depth of eld is indicated by
the area between the depth-of-eld scale lines
below the distance scale. The numbers on the
scale are F values.
 The depth-of-eld scale position changes due
to zooming. For f/8, when the display space
becomes narrow the display disappears and only
the scale which shows f/8 is displayed. When
moving closer to the telephoto end (300 mm), the
scale which shows f/8 also disappears.
 The depth-of-eld scale is only to serve as a
guide.
