• First attach the Extender to the lens, then attach the lens to the camera. Detach it from the
camera in the reverse order. If you attach the lens to the camera first, misoperation may
occur.
• With the EF1.4X II Extender attached, autofocusing is enabled from 0.8 m/2.6 ft. to infinity.
Autofocus mode cannot be used to take pictures closer than 0.8 m/2.6 ft. due to the relation
with the effective F value, so use manual focusing.
• If you use an Extender on the lens mounted on a EOS A2/A2E/5, set the exposure
compensation to -1/2 stop for the EF1.4X ll or -1 stop for the EF2X ll.
• Only one Extender can be attached to the lens and camera.
