respectively.

aSafety Precautions
5
• Do not look at the sun or a bright light source through the lens
with the extender attached, or with a camera with the extender
and lens attached. Doing so could result in visual impairment. In
2                                                    particular, never look at the sun directly through the lens with the
extender attached, because that could result in loss of vision.
• Do not leave the lens with the extender attached, or a camera
with the extender and lens attached in the sun without the lens
4                cap on. That may result in concentrating the sun's rays, causing a
3                                                    fire.
Mounting and dismounting the Extender
First attach the Extender to the lens, then attach it to the camera. To
1
detach it, follow the same procedure in reverse.
To detach the Extender from the lens, slide the lens release lever as
shown by the arrow, then turn the Extender counterclockwise.

Maximum Aperture with the Extender
When Extender EF1.4X II is attached, the lens maximum aperture will
be smaller (darker) by 1 stop. With Extender EF2X II, the maximum
COPY
aperture will be smaller by 2 stops. In any case, the camera will
3                                                   compensate the exposure automatically.
2                                       4           Caution
• Do not attach two or more Extenders on the same camera. Doing so
will degrade the optical performance and the camera will not be able
to obtain proper exposure readings.
q Lens mount index (on lens)                              • To enhance water and dust resistance, the Extender EF1.4X II and
w Lens mount index (on camera)                              EF2X II have a rubber ring around the mount. As the lens is
e Lens release lever                                        repeatedly mounted and detached, the rubber ring will leave fine
r Contacts                                                  abrasion marks on the outside of the camera mount. This will not
t Rubber ring                                               affect operation.
The rubber ring can be replaced by a Canon service center (a fee
Usable lenses:                                              will be charged).
• Autofocusing slows down when the lens is used with an extender, in
Focal Length & Maximum Aperture    order to maintain the precision of autofocus control.
