Safety
Precautions
e 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.
e
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.
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, please
check the Canon website for the
latest
camera firmware.
If
the camera's firmware is
not the
latest
version, be sure to update to the latest
firmware.
e
For
details on updating firmware, please check the Canon website.
Cautions
during
shooting
e
This
lens uses a stepping motor to drive the focusing lens
(the lens
that has the job of focusing the shot).

focus mode.
2.
Cautions when the
lens
is
in
sleep
mode
This
lens has a
sleep
mode separate from the camera auto power-off function for saving power when the
lens
has not been operated for a period of time.
Since
the motor does not operate when the lens is in
sleep
mode,
even
if the camera is turned on, take note of
the following
points.
•
The focus cannot be adjusted in
manual
focus mode.
•
To
recover the
lens
from
sleep mode, press the shutter button
halfway.
