• 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 Extender EF2X II attached to the lens, only manual focus is possible. However, with the EOS- 1Ds Mark III, EOS-1Ds Mark ll, EOS-1Ds, EOS-1D Mark lll, EOS-1D Mark ll N, EOS-1D Mark ll, EOS-1D, EOS-1V/HS, EOS-3 camera, autofocusing with the center focusing point is possible.

•Only one Extender can be attached to the lens and camera.

•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.

• Autofocusing is still enabled with Extender EF1.4X II attached.

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