The Canon EF 200-400mm f/4L IS USM Extender 1.4x is the world’s first SLR lens that has an inbuilt teleconverter. These lenses are flexible enough to be turned to a 280-560mm f/5.6 optic, just with a simple flick of a switch that is on the top of its barrel.

DGElectronics’s Camera Shop Singapore rank this model as one of the best Canon EF lenses.
