*When an Extender EF 1.4⋅ ll is attached, the AF speed becomes slower to maintain adequate AF control.

• With Extender 2⋅ ll attached to the lens, only manual focus will be possible. The only exceptions are with the EOS-1V/HS, 3, 1Ds Mark II, 1Ds, 1D Mark II N, 1D Mark II, and 1D which can still autofocus, but only with the center focusing point.
