aSafety Precautions
Do not look at the sun or a bright light source through the lenswith the extender attached, or with a camera with the extenderand lens attached. Doing so could result in visual impairment. Inparticular, never look at the sun directly through the lens with theextender attached, because that could result in loss of vision.Do not leave the lens with the extender attached, or a camerawith the extender and lens attached in the sun without the lenscap on. That may result in concentrating the sun's rays, causing afire.

Mounting and dismounting the Extender

First attach the Extender to the lens, then attach it to the camera. Todetach it, follow the same procedure in reverse.To detach the Extender from the lens, slide the lens release lever asshown by the arrow, then turn the Extender counterclockwise.

Maximum Aperture with the Extender

When Extender EF1.4X II is attached, the lens maximum aperture willbe smaller (darker) by 1 stop. With Extender EF2X II, the maximumaperture will be smaller by 2 stops. In any case, the camera willcompensate the exposure automatically.

Caution

Do not attach two or more Extenders on the same camera. Doing sowill degrade the optical performance and the camera will not be ableto obtain proper exposure readings.To enhance water and dust resistance, the Extender EF1.4X II andEF2X II have a rubber ring around the mount. As the lens isrepeatedly mounted and detached, the rubber ring will leave fineabrasion marks on the outside of the camera mount. This will notaffect operation.The rubber ring can be replaced by a Canon service center (a feewill be charged).Autofocusing slows down when the lens is used with an extender, inorder to maintain the precision of autofocus control.If you have an EOS A2/A2E/5 and use an Extender with any of thelenses listed above, set -1/2-stop exposure compensation with theEF1.4X II or -1 stop with the EF2X II.
