Canon Extender RF 1.4x review: a revamped teleconverter for the EOS R-system

Canon Matthew Richards

Canon Extender RF 1.4x.

The Canon Extender RF 1.4x is designed for EOS R-system mirrorless Canon cameras and compatible RF-mount Canon telephoto lenses. As such, it builds on the strength and reputation of the latest Canon Extender EF 1.4x III for DSLRs, which can also be used on EOS R cameras via an EF-EOS R mount adapter. Aimed at professional and enthusiast photographers, it sets out to be one of the world’s best teleconverters.

Even with its front and rear caps fitted, the Canon Extender RF 1.4x is small enough to slip into a coat pocket. (Image credit: Matthew Richards)
