Canon Extender RF2x
Extra reach without needing an extra lens: There are times when I want to photograph a far-away subject, like the surface of the moon, but don't have a lens long enough for the job. That's when an extender (sometimes known as a teleconverter) becomes quite handy. This extender doubles your effective focal length when paired with a compatible RF Series telephoto lens. If you shoot with Canon RF Series lenses, the Extender RF2x may well be worth considering for your kit.
