Conventions used in these instructions
Warning to prevent lens or camera malfunction
or damage.
Supplementary notes on using the lens and
taking pictures.

ENG-2
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.
zDo not look directly at the sun or other strong
light sources through a lens. This may result in
loss of sight.
zDo 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.
zDo not leave a lens in the sun without the lens
cap attached. The lens may concentrate entering
sunlight and cause a malfunction or fire.
Caution Details pertaining to risks that may
result in injury or damage to other
objects.
zDo not leave the product in places exposed to
extremely high or low temperatures. The product
may cause burns or injury when touched.
zDo not insert your hand or fingers into the
product. This may result in injury.
zAttach a tripod or monopod that is sufficiently
sturdy to the tripod mount on the lens.
Safety Precautions

ENG-3
Handling Precautions
zDo not leave the product in excessive heat such as
in a car in direct sunlight. High temperatures can
cause the product to malfunction.
zIf 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.
zThe interior of the lens may appear to shake, but
this is not a malfunction and will not cause any
problems.
zPlease also read any lens related handling
precautions listed in your camera’s instruction
manual.
General Precautions
Shooting Precautions
The lens uses a DO* lens. Colored flare might appear
around the light source depending on shooting
conditions, which is due to DO lens characteristics.
zFor scenes where a light source is inside the
screen, colored flare may occasionally appear as
a halo of light around the light source.
zFor scenes where a light source is outside the
screen, colored flare may occasionally appear
partially inside the screen. You can reduce or
prevent these issues with the following steps
according to the scene you are shooting.
• Use your hand or paneling, an umbrella, etc.
to block the light source and placed so that
they do not appear in the screen.
* “DO” stands for Diffractive Optics.
Use of a DO lens provides favorable correction of
chromatic aberration that occurs easily in super-telephoto
lenses, achieving a more compact and lightweight design
while providing good rendering capabilities.

ENG-4
General Precautions
Shooting Precautions
The aperture setting is fixed at f/11 on this lens, and cannot be adjusted.
Adjust exposure using the shutter speed and ISO speed.
zBe aware of the following when selecting a shooting mode.
•If [P] mode is selected, shutter speed is adjusted while the aperture setting remains fixed at f/11, and so actually it is
the same as if selecting [Av] mode.
•If [Av] mode is selected, the aperture setting cannot be adjusted.
•If [Tv] mode is selected, the aperture setting is not adjusted, and so actually it is the same as if selecting [M] mode.
•If [Fv] mode is selected, it is actually the same as if selecting [Av] or [M] mode, depending on the shutter speed and
ISO speed settings.
zAlso be aware of the following when shooting.
•Since the aperture setting cannot be changed, the effect gained from stopping down (depth of field) cannot be
adjusted.
•When using safety shift and the camera automatically changes the manual settings to allow shooting at standard
exposure, the aperture setting is not adjusted.
•During AEB (auto exposure bracketing), the aperture setting is fixed at f/11 and does not change.
•When using Portrait mode in the Special Scene Modes (on EOS RP cameras), the depth of field cannot be adjusted
for a shallower depth, since the aperture setting cannot be adjusted.

2. Preparing to Shoot (Extending/Retracting the Lens)
Extend the lens barrel
frontward.
Turn the lock ring toward
“UNLOCK” all the way until
you hear a click.
zThe lock ring clicks when you
turn it all the way in either
direction.
Before shooting, extend the lens barrel to the shooting position and lock it as follows. You cannot
shoot while the lens is retracted.
With the lens barrel extended,
turn the lock ring toward
“LOCK” all the way until you
hear a click.
● The lens barrel is locked.
zThe lens barrel can only be extended or retracted when the lock ring is at “UNLOCK”.
zNote that when the lock ring is at “UNLOCK”, the lens barrel may sometimes become extended or retracted
unintentionally. Always hold the camera and lens securely when at “UNLOCK” and you are extending or
retracting the lens barrel.
zTo retract the lens barrel, follow the same steps, this time retracting the lens barrel and then turning the lock
ring toward “LOCK” all the way until you hear a click.
zThe lock ring can only be turned when the lens barrel is extended or retracted all the way.

Focus mode switch
Focusing ring
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.
3. Setting the Focus Mode
zBe sure to update the camera’s firmware so it is
compatible with this lens.
zThe range-finding area with the camera* after
updating the firmware is an area of the image
plane of approx. 40% horizontal x approx. 60%
vertical.
This remains constant even if an extender is
attached.
zQuickly turning the focusing ring may result in
delayed focus.
* As of March 2020: EOS R, EOS Ra, EOS RP
zThe lens’ focusing ring is electronic.
zWhen AF operation is set to [ONE SHOT],
manual focus is possible after autofocusing
has been completed by continuing to press the
shutter button halfway. (Full-time manual focus)
However, the camera settings need to be
changed. Please refer to the camera’s
instructions for details.
