Thank you for purchasing a Canon product.

Safety Precautions
- 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 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 cap on. That may result in concentrating the sun’s rays, causing a fire.
- Do not leave the extender in excessive heat such as in a car in direct sunlight. High temperatures can cause the extender to malfunction.
Mounting and dismounting the Extender
- First, attach the Extender to the lens, then attach it to the camera. To 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.

- Using an Extender with this lens may result in incorrect autofocus.
- If your camera has an AF micro-adjustment function, do the AF micro-adjustment.
- If your camera does not have an AF micro-adjustment function, focus manually if the AF precision is way off.
- For details on AF micro adjustments, see the camera’s instruction manual.
- Refer to the camera and lens instruction booklets to see if there are any AF compatibility limitations.
- The maximum aperture is indicated in half-stop increments.
Maximum Aperture with the Extender
When Extender EF1.4X IIl is attached, the lens maximum aperture will be
smaller (darker) by 1 stop. With Extender EF2X III, the maximum aperture will
be smaller by 2 stops. In any case, the camera will compensate the exposure
automatically.
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.
- To enhance water and dust resistance, the Extender EF1.4X III and EF2X III have a rubber ring around the mount. As the lens is repeatedly mounted and detached, the rubber ring will leave fine abrasion marks on the outside of the camera mount.
- This will not affect operation.
- The rubber ring can be replaced by a Canon service center (a fee will be charged).
- Autofocusing slows down when the lens is used with an extender, in order to maintain the precision of autofocus control.
- The Extenders cannot be used with film cameras other than the EOS-1V. Using an Extender with a film camera other than the EOS-1V may cause misoperation.
