• 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

• 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 II or -1 stop for the EF2X II.

When an Extender is attached, the AF speed will become slower by design to retain proper AF
control.
