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 lens interior may appear to waver, but this
does not indicate a defect or failure, and will not
cause any problems in use.
zIn order to optimize aperture control, there are
occasions in which the aperture blades will move
during zooming and focusing, even when the
aperture value is set for aperture-priority AE or
manual exposure, etc.
zPlease also read any lens related handling
precautions listed in your camera’s instruction
manual.

the image stabilizer switch to OFF.
Image stabilizer mode selector switch
2Select an Image Stabilizer mode
according to the application and shooting
conditions.
Image Stabilizer modes
zMODE 1: Corrects vibrations in all directions.
It is suited to shooting still subjects.
zMODE 2: When you take a panning shot either horizontally or vertically, corrects vibrations at right
angles to the direction of panning.
It is suited to shooting moving subjects.
zMODE 3: During exposure, corrects vibrations in the same way as MODE 2.
Since vibration is corrected only during exposure, It is suited to shooting irregularly
moving subjects.

ENG-11
The Image Stabilizer for this lens is suited to hand-held shots in the following conditions.
Image Stabilizer
MODE 1
Shooting still subjects
zIn semi-darkened areas such as indoors or
outdoors at night.
zIn locations where the flash cannot be used,
such as art museums and theater stages.
zIn situations where your footing is uncertain.
zIn situations where fast shutter speed settings
cannot be used.
MODE 3
Shooting irregularly moving subjects
zPanning shots of
vehicles, trains, etc.
MODE 2
Shooting moving subjects
zSports photography
of soccer, basketball,
etc.

Image Stabilizer
zThe Image Stabilizer cannot compensate for a
blurred shot caused by a subject that moved.
zThe Image Stabilizer might not be fully effective in
the following conditions:
• Large shake or fast vibration
• Panning in MODE 1
zWhen using a tripod, it is recommended that you
set the image stabilizer switch to OFF.
zEven 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.
