Canon Extender RF 2x
Canon Extender RF 2x


The Canon Extender RF 2x mounts between your RF-mount camera body and RF-mount lens in order to give your lens more reach through magnification. It features a built-in microcomputer for seamless communication among camera body, lens and extender. Note that this extender reduces your maximum aperture by 2 stops. It is recommended that you attach the extender to your lens and then attach the pair to your camera body. Extenders allow photographers to shoot from greater distances without having to resort to using larger and longer lenses. They are compatible with both full frame and crop frame sensor cameras and they are ideal for sports and wildlife.

Compatibility may expand over time. Currently, this extender is designed for the following lenses:

  • Canon RF 600mm f/11 IS STM Lens
  • Canon RF 800mm f/11 IS STM Lens

  • • Not all lenses are compatible with this extender. For a list, see this guide. If it’s not listed in that guide, it may still be compatible but we can't guarantee it and it'll be a risk.
