Extenders (Sold Separately)

  • Attach the extender to the lens, and then attach the OO lens to the camera. To remove it, reverse the order. Errors may occur if you attach the extender to the camera first.
  • When shooting with EOS A2/A2E/5 fitted with either the EF300mm f/2.8L IS II USM or EF400mm f/2.8L IS II USM, use -0.5 step exposure compensation when using extender EF1.4x II, and use -1 step exposure when using extender EF2x AF is possible with extender EF1.4x II/III or EF2x II/III.
  • When an extender is attached, the AF speed will become slower to retain proper control.
