6. Power Focus (PF) Mode
Using the playback ring enables smooth focus change.
This is a useful feature for changing focus when shooting movies.
When the playback ring is rotated in a certain direction, focus changes in the same direction as 
when the focusing ring is rotated.      
You can make a 2-step change in focus shift speed depending on the angle that the playback ring is 
rotated to.
 With the focus preset switch set to OFF, set the focus mode 
switch  to PF. Rotate the playback ring to 
change  the focus.

8. Image Stabilizer
You can use the image stabilizer in AF, PF, or MF mode.
Also, the Image Stabilizer can be used regardless of the internal extender setting (either 1x or 1.4x).
 Set the STABILIZER switch 
to ON.
●●If you are not going to use the 
image stabilizer function, set 
the switch to OFF.
 Select the stabilizer mode.
●● MODE 1: Corrects vibrations in 
all directions. It is mainly effective 
for shooting still subjects.
●●MODE 2: Corrects vertical 
camera shake during 
following shots in a horizontal 
direction, and corrects 
horizontal camera shake 
during following shots in a 
vertical direction.
●● MODE 3: Corrects vibration 
only during exposure. During 
panning shots, corrects vibration 
during exposure only in one 
direction the same as MODE 2.
 First press the shutter 
button 
down halfway, then 
press down all the way to 
take the picture.
●● MODE 1, 2: Press the 
shutter button down halfway 
to stabilize the image in 
the viewfinder and enable 
stabilization.
●● MODE 3: Press the shutter 
down halfway to initiate 
computation of stabilization, 
then press down all the way 
to enable stabilization.

9. 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 3
●●Since camera shake is stabilized only during 
exposure, following a subject is easier such 
as when shooting a fast and irregularly 
moving player during sports photography.

Tips on Using the Image Stabilizer
●●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.
●● 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.
●● Please refer to the Camera/Extender Compatibility 
Chart (p.25) for information regarding IS operation 
when using external extenders.
●●Using a tripod also stabilizes the image.  
However, depending on the kind of tripod and 
shooting conditions, sometimes it may be better 
to turn off the Image Stabilizer function.
●● The stabilizer is equally effective for hand-
held photography and photography with a 
monopod. The Image Stabilizer effect may be 
reduced, however, depending on the shooting 
environment.
●● 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.

10. Internal Extender Switch
The extender switch lever allows you to set the focal distance of the lens to 1.4x.
 Slide the extender switch 
lock toward the front of the 
lens.
●● This allows the extender 
switch lever to move.
 Use the extender switch 
lever to select a focal 
distance of either 1x or 1.4x.
●●This allows you to change the 
focal distance of the lens to 
either 1x or 1.4x.
 Slide the extender switch 
lock 
toward the back of the 
lens.
●● This locks the extender switch 
lever in place.
The extender switch lock prevents the extender switch lever from being moved inadvertently. It does not 
secure the switch lever to the side edge. Be sure to use the lock even when the switch lever is set at 1x in 
order to prevent it from being moved inadvertently.
When the internal extender is used (set to 1.4x), the AF speed will become slower to retain proper control.

Precautions for Using the Internal Extender●●Please do not move the internal extender switch in any of the following situations or when the camera 
is in operation. Doing so will cause the camera or lens to malfunction.
●• Wh

en the shutter button is pressed half way down. (not applicable to Group 2 cameras)
●•Wh

en the shutter button is pressed all the way down.
●•Wh

en the lens or camera is in operation (during Auto Focus, Image Stabilization*, exposure, 
continuous shooting, use of the focus preset, power focus operation, etc.).
●• Wh

en the camera is set to Live View shooting. (not applicable to Group 2 cameras)
●•Wh

en the camera is set to Movie Shooting. (not applicable to Group 2 cameras)
If you have moved the internal extender switch in any of the situations listed above, please be sure 
to turn the camera OFF. Then, move the switch back to the correct position when the viewfinder is 
activated, and when the camera and lens are not in operation.
●● When moving the internal extender switch, please wait around two seconds before switching to 
different shooting styles (shooting with the viewfinder, Live View shooting, and movie shooting). Not 
doing so may result in an error message being displayed (ERR01) and prevent shooting operation. 
Turn the camera OFF and then ON to clear the error message.
●● Be sure that the extender switch lever is positioned correctly. Not positioning the lever correctly will 
create shadows in images and cause AF, AE, and other functions to not work properly.
●● When set to 1.4x, the amount of light is reduced where the focal length was extended (the f-number 
becomes one step darker). Therefore, please adjust the exposure after switching to the 1.4x setting.
●● The focus position may be altered due to changing the internal extender setting. Therefore, please 
adjust the focus after changing the internal extender setting.
●● When the internal extender setting is changed, the camera will display an aperture value between f/4 
and f/5.6 (maximum aperture). However, the aperture value displayed will not change when the lens 
is not in operation or when the lens shuts down in order to save power. When this occurs, the correct 
aperture value can be displayed by pressing the shutter button halfway to reactivate the lens.
* The Image Stabilizer will remain in operation for around two seconds after lifting your finger off of the shutter button.

12. Hood
The special hood that comes with this lens cuts 
out unwanted light and protects 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.
11.  Infinity Compensation 
Mark
For accurate focusing in MF on subjects at infinity 
distance, look through the viewfinder or at the 
camera’s LCD display while rotating the focusing 
ring.
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 distance 
scale L mark is aligned with the distance index.
