7. Tips on Using the Image Stabilizer
●In semi-darkened areas such as indoors or
outdoors at night.
● In locations where flash photography is
prohibited, such as art museums and theater
stages.
● In situations where your footing is uncertain.
● In situations where fast shutter settings
cannot be used. ●
When panning subjects in motion.
● MODE 1 ●MODE 2

The image stabilizer for this lens is effective for hand-held shots in the following conditions.

							ENG-11
●The Image Stabilizer cannot compensate for a
blurred shot caused by a subject that moved.
● Set the STABILIZER switch to OFF when you
are taking pictures using the Bulb setting (long
exposures). If the STABILIZER switch is set to
ON, the image stabilizer function may introduce
errors.
● The Image Stabilizer might not be fully effective
in the following cases:
• You shoot from a violently moving vehicle.
• You move the camera dramatically for a
panning shot in Mode 1.
• You shoot using techniques other than following shots in Mode 2.
● The Image Stabilizer consumes more power
than normal shooting, so fewer shots can be
taken if you use the function.
● The image stabilizer operates for about two
seconds even when your finger is off the shutter
button. Do not remove the lens while the
stabilizer is in operation. This will cause a
malfunction.
● With the EOS-1V/HS, 3, ELAN 7E/ELAN
7/30/33, ELAN 7NE/ELAN 7N/30V/33V, ELAN
II/ELAN II E/50/50E, REBEL 2000/300, IX, IX
Lite/IX7, and D30, the Image Stabilizer will not
work during self-timer operation.
Tips on Using the Image Stabilizer
●When you use a tripod, the Image Stabilizer
should be turned off to save battery power.
● The stabilizer is equally effective for hand-held
photography and photography with a monopod.
● The Image Stabilizer also operates when the
lens is used with extension tube EF12 II or EF25
II or the extender EF1.4 ×II.
● The Image Stabilizer also operates when the
EF300mm f/2.8L IS USM or EF400mm f/2.8L IS
USM is used with the extender EF2 ×II.

●When using the extender EF2 ×II with the
EF500mm f/4L IS USM or EF600mm f/4L IS
USM, you can use the Image Stabilizer with the
following cameras: EOS-1Ds Mark III, EOS-1Ds

● Depending on the camera there may be image
shake, such as after releasing the shutter.
However, this does not affect shooting.
● If you set the camera’s Custom Function to
change the assigned button to operate the AF,
the Image Stabilizer will operate when you press
the newly assigned AF button.
8.Infinity Compensation Mark
To   compensate for shifting of the infinity focus
point that results from changes in temperature.
The infinity position at normal temperature is the
point at which the vertical line of the L mark is
aligned with the distance indicator on the
distance scale.

9. Depth-of-Field Scale
The depth of field is the distance in front of and
behind the plane of focus on the subject that
appears sharp. The depth of field is indicated by
the area between the depth-of-field scale lines
below the distance scale. The numbers on the
scale are F values.

10. Using the Tripod Mount
Adjusting the Tripod MountBy loosening the orientation locking knob on the tripod mount you can ro\
tate the camera to set the
image for any vertical or horizontal position.
Detaching the Tripod Mount(EF300mm f/2.8L IS USM only)
First remove the lens from the camera and then remove the tripod mount f\
rom the lens as shown
below. To attach the tripod mount, reverse the procedure.
Align the red mark on the
tripod mount with the lens
mount index.
Loosen the orientation
locking knob.
Slide off the tripod collar
away from the rear of the
lens.

11. Hood
The special hoods that come with all these
lenses cut out unwanted light and protect the
front of the lens from rain, snow, and dust.
To  attach the hood, loosen the hood lock knob
by turning it counterclockwise. Fit the hood onto
the lens’s hood mount, and tighten the lock knob
to fix it in place. Use the same procedure, in
reverse, to remove the hood.
12. Case
Put the lens away as follows.
Reverse the lens hood, slip it over the lens, and attach the lens cap. 
Position the tripod mount straight upwards as shown and place it in the case.
Fasten the lens securely with the strap.
Push the lever while holding the lid from above to lock.

straight up out of the slot.
To   install the drop-in filter, push the filter holder
straight down into the slot until it clicks into place.
● The filter holder can be installed facing either
forwards or backwards.

The Drop-In Screw-Type Filter Holder 52 and Drop-
In Circular Polarizing Filter PL-C52 are also
available (sold separately).
Because the lens optics are designed to include a
glass filter, you must always install the filter holder,
even if no gelatin filter is fitted.
Lift up the holder’s retaining plate.
Cut the gelatin filter as shown and mount it in
the holder.
Return the retaining plate to its closed position.

●Attach the extender to the lens, and then attach the lens to the camera.\
 To remove it, reverse the order.
Errors may occur if you attach the extender to the camera first.
● When using the extender EF2 ×II with the EF500mm f/4L IS USM or EF600mm f/4L IS USM, the focusing
mode is MF mode. However, AF shooting is possible only with the center focusing point when the cam\
era is
EOS-1Ds Mark III, EOS-1Ds Mark II, EOS-1Ds, EOS-1D Mark III, EOS-1D Mark\

●When shooting with EOS A2/A2E/5 fitted with
either the EF300mm f/2.8L IS USM or
EF400mm f/2.8L IS USM, use –0.5 step
exposure compensation when using extender
EF1.4 ×II, and use –1 step exposure when using
extender EF2 ×II.
● When taking pictures on an EOS A2/A2E/5
using an  EF1.4×II/EF2 ×II extender with the
EF500mm f/4L IS USM or the EF600mm f/4L IS
USM, use the values in the table below for
exposure compensation.
● Extenders cannot be used more than one at a
time.
