Are They Compatible with the Canon Ef 70/200 L USM Lens
Yes, it's compatible with all EF lenses
No, they are not compatible with all EF lenses. If you look at the physical protruding elements of the extenders, they require lenses that have the large, hollow rear openings (such as the Canon EF 70-200mm f/2.8L or f/4.0L lenses) as opposed to the Canon EF 24-70mm f/2.8L lens, which has a closed rear element.
