• AF is possible with Extender.
• When an Extender is attached, the AF speed will become slower by design to retain proper
AF control.
• Do not attach more than one Extender on the same lens. Having more than one Extender on
the lens will degrade the optical performance and cause exposure errors by the camera's
built-in exposure metering.
• 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 EF 1.4X ll or -1 stop for the EF 2X ll.
