Instructions
Handling Cautions
Safety 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, 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.
● 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.
● 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.
● Do not leave the lens in excessive heat such as in a
car in direct sunlight. High temperatures can cause
the lens to malfunction.

Shooting Precautions
The EF24-105mm f/3.5-5.6 IS STM utilizes a stepping motor that drives the focus lens.
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 per off function.
In this state, the motor will not operate even if the camera . Threfore, 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 buttohalfway.
ENG-4
3. During initial reset
When the camera is ON or when the camera is turned ON by pressing the shutter button halfway down when the
camera is OFF due to the use of the auto power off function*1, the lens performs an initial reset of the focus lens.*2
● Although the image in the viewfinder will appear out of focus during the initial reset, this does not mean that the
lens has malfunctioned.
● Although the shutter can be released during the initial reset, users must wait approximately 1 second*3 after the
initial reset has completed before shooting.
*1: Not applicable to the following EOS camera models:
EOS REBEL T5i/700D, EOS REBEL SL1/100D, EOS REBEL T4i/650D
*2: With some cameras, the lens may perform an initial reset in order to improve lens performance even at times
other than described in this section.
*3: The initial reset time varies depending on camera being used.
When using the lens with film-bed SLR cameras
● The drive speed of the focus lens will be slower then the lens is used with a digital camera.
● Images will appear out of focus when using the cainternal flash while it is charging or when zooming
during exposure for still images.
● Even when the camera is ON, images may pper out of focus when zooming. If this occurs, press the shutter
button halfway while zooming.
● After focusing in 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 approximately 1 second after zooming before the auto focus will
function.

1. Mounting and
2. Zooming
Detaching the Lens
See your camera’s instructions for details on
mounting and detaching the lens.
To zoo, turn the lens’ zoom ring.
● Be sure to finish zooming before focusing.
Zooming after focusing can affect the focus.
● Blurring may temporarily occur if the zoom ring is
quickly rotated.
● Zooming when the camera is OFF will result in
delayed focus.
● Zooming during still image exposure will result in
delayed focus. This causes any streaks of light
that are captured during exposure to be blurred.
● After detaching the lens, place the lens with
the rear end up to prevent the lens surface an
contacts from getting scratched.
● If the contacts get soiled, scratched, or ave
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 as shown
in the diagram, and turn clockwise. To remove it,
reverse the order.

3. Setting the Focus Mode
● Quickly rotating the focusing ring may result in
delayed focus.
● Manual focus adjustments are not possible when
the camera is OFF.
● Please make sure that the camera is kept ON
after bringing an image into focus. However,
there are times when images will become out
of focus even when the camera is ON due
to changing the camera battery or attaching/
deaching the lens. Please use the camera’s
ao power off function to maintain focus when
the amera is OFF.
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.
After autofocusing in ONE SHOT AF mode, focus
manually by pressing the shutter button halfway
and turning the focusing ring. (Full-time manual
focus)

6.
Image Stabilizer
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).
● The Image Stabilizer cannot compensate for a
blurred shot caused by a subject that moved.
● 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.
● Wen shooting a still subject, it compensates for
caera shake in all directions.
● It compensates for vertical camera shake during
following shots in a horizontal direction, and
compensates for horizontal camera shake during
following shots in a vertical direction.
● When you use a tripod, the Image Stabilizer
should be turned off to save battery power.
● Even with a monopod, the Image Stabilizer will
be as effective as during hand-held shooting.
However, depending on the shooting environment,
the Image Stabilizer effect may be less effective.
