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 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 diaphragm 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.

4. Adjusting the Zoom and Zoom Ring Operational Feeling
To zoom, turn the zoom ring.
zBe sure to finish zooming before focusing.
Zooming after focusing can affect the focus.
zBlurring may temporarily occur if the zoom ring is
quickly turned.
zPlease be careful not to let your fingers get
caught in between the lens’ front and the zoom
ring when zooming.
Adjustment ring
You can adjust the operational feeling (weight
of movement) of the zoom ring to a preferred
level. Turn the adjustment ring toward SMOOTH
to lighten the feeling, and toward TIGHT to
strengthen it.
zIt is recommended that the adjustment ring is
turned fully to the TIGHT setting when not in
use to prevent the front of the lens from being
unintentionally extended.
zIf the lens is aimed upward or downward in the
TELE setting with the adjustment ring set at
SMOOTH, there are cases in which the lens will
contract to the WIDE setting. Please be careful
not to let your fingers get caught in between the
lens’ front and the zoom ring.

ENG-9
The control ring can be assigned the functions
that are commonly used with cameras, such as
shutter speed and aperture settings.
Control ring
The click action of the control ring allows you to
have a sense of how much it is being turned.
Please refer to the camera’s instructions for
details on how to use the control ring.
zThere are cases in which the sound of control
ring operations may be recorded when shooting
movies.
zThe clicking sensation of the control ring can
be removed by the Canon Service Center.

zIf you are not going to use image stabilization, set
the image stabilizer switch to OFF.

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.
zPhotography of
animals

ENG-12
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, the Image Stabilizer might
not be fully effective or it might be better to set the
image stabilizer switch to OFF, depending on the
type of tripod and where the tripod is located, as
well as on the camera’s settings such as shutter
speed.
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.

ENG-16
It is possible to increase the size of the subject when shooting with the use of the RF1.4x and RF2x
extenders.
Attaching
zFirst of all, use the zoom ring to set the focusing distance at between 300 mm and the TELE
setting (500 mm).
zThen attach the extender to the lens. The lens can be attached to the camera after this.
zAttaching the extender forcibly with the focusing distance set between 300 mm and the WIDE setting may
result in malfunctions or other damage.
z
The range of zoom operations with the extender attached is within a focusing distance of 300 mm to 500 mm.
zMore than one extender cannot be used.
zThe range-finding area for this lens will differ depending on the combination of camera and extender in use.
Please check the Canon website for further details.
Lens specifications when using extenders are as follows.

zIf the focusing distance is set at 300mm when the extender is detached, there are cases in which it will not
be possible to turn the zoom ring toward the WIDE setting from the 300mm point after it has been removed.
zIn either of these events, turn the zoom ring slightly toward the TELE setting to release the zoom ring so
that it can be turned to the WIDE setting. You may hear a noise during this, but it will have no effect on
operations.
zThe speed of the AF will be slower when an extender is in use on account of controllability.

11. Close-up Lenses
(Sold separately)
You can attach filters to the filter mounting thread
on the front of the lens.
zOnly one filter may be attached.
zIf you need a polarizing filter, use the Canon

zPlease refer to p.14 for details on how to use
the circular polarizing filter.
Attaching a 500D (77 mm) Close-up Lens
enables close-up photography.
It provides a magnification of 0.2x to 0.98x.
zClose-up Lens 250D cannot be attached
because there is no size that fits the lens.
zMF mode is recommended for accurate
focusing.
