Where I find a list of non-Canon lenses that are compatible with a Canon EF 1.4X & 2.0 Extenders?

From Canon .............................................

The list of Canon EF lenses that are officially compatible with Canon’s EF Extenders includes the following:

All fixed focal length, L-series Canon telephoto lenses — 135mm or longer
(note that this includes the EF 180mm f/3.5L USM macro lens)
All L-series Canon EF 70–200mm L-series zoom lenses, both f/2.8 and f/4 versions
The EF 100–400mm f/4.5-5.6L IS USM and the EF 200–400mm f/4L IS USM Extender 1.4x
(note that the EF 200–400mm f/4L IS USM Extender 1.4x can use EF 1.4x or 2x Extenders, in addition to its built-in 1.4x Extender)

All other Canon EF, EF-S, TS-E and MP-E lenses are officially not compatible with Canon’s EF Extenders and we do not recommend attaching them. Some photographers use accessories like an EF12 Extension Tube to allow physical attachment of an EF Extender to non-compatible lenses and in some cases, they get good images. Likewise, some shooters have used the same Extension Tube to permit “stacking” two or more tele extenders onto a lens. But please understand that Canon does not officially recommend or endorse the use of EF Extenders with non-compatible lenses and we cannot guarantee proper operation.
