It will work in the sense that you will get a 1.4X magnification, but the Rebels won't autofocus since f/4.5*1.4 results in an effective aperure smallewr than f/5.6.

"Does the 1.4 111 telephoto extender work ..."

 

It is not just this extender, no 1.4 extender will work.

EOS 1DX and 1D Mk IV, even less and less other stuff.
