The lens can be used with Extender EF 1.4
× ll and 2× ll. The lens
specifications when an Extender is attached are shown below.
* 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.
