Canon Extender RF 2x review: double your telephoto reach and close-up magnification

Canon Extender RF 2x.

The name is a giveaway and, as you’d expect, the Canon Extender RF 2x is designed for EOS R-system mirrorless Canon cameras and compatible RF-mount Canon telephoto lenses. It therefore builds on the reputation and performance prowess of the latest Canon Extender EF 2x III for DSLRS, which can also be used on EOS R cameras via an EF-EOS R mount adapter. It sets out to be one of the world’s best teleconverters, aimed at professional and enthusiast photographers.

The Canon Extender RF 2x is nicely compact small and won’t take up much room in your gadget bag. (Image credit: Matthew Richards)
