4. Equipped with an Image Stabilizer that provides
an image stabilization effect equivalent to a shutter
speed
3.5
stops*2 faster (telephoto end, when
used with the EOS 70). The Image Stabilizer also
provides optimal image stabilization that responds
to shooting conditions (such as shooting still
subjects and following shots).
5.
Electronic manual focusing (MF) made possible
by
electronically detecting the rotation of the focusing ring.
6. Manual focusing is available after the subject comes
into focus
in
autofocus mode (ONE SHOTAF).
7.
Circular
aperture
for
producing beautiful
softfocus images.
*1: Function compatible with the following camera (as
of
July 2013):
EOS REBEL T5i/700D, EOS REBEL SL1/1000,
EOS REBEL T4i/650D, EOS M (when using with
Mount Adapter EF-EOS M)
*2: Image stabilization performance based
on
CIPA
(Camera & Imaging Products Association) Standards.
During actual shooting, image stabilization
performance varies depending
on
the amount of
camera shake, shooting conditions, and other factors.

Handling Cautions
e
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.
e Do not leave the lens
in
excessive heat such as
in
a car
in
direct sunlight. High temperatures can cause the
lens
to
malfunction.
Usage Precautions
e When using this lens with
an
EOS REBEL T4i/650D
camera, please be sure to update the camera's
firmware to version 1.0.4 or later.
e Ifthe EOS REBEL T4i/650D firmware is
an
earlier
version than 1.0.4, there is a slight chance that the
camera will stop operating. If this occurs, please remove
the battery temporarily and insert it again for correct
camera operation.
e For information
on
firmware updates, please check the
Canon website.

Safety
Precautions
• 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.

Shooting Precautions
The EF-S55-250mm f/4-5.6
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.
e
Manual focus adjustments are not possible.
e
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.
e
During zooming, delayed focus will occur.
•
To
exit sleep mode, press the shutter button halfway.
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.
e
Although the image
in
the viewfinder will appear out
of
focus during the initial reset, this does not mean that the
lens has malfunctioned.
e
Although the shutter can be released during the initial reset, users must wait approximately 1 second*2 after the
initial reset has completed before shooting.
