Canon RF and EF extenders, also known as teleconverters, are accessories that can be attached to the back of specific Canon RF and EF lenses to increase their focal length. Note not all RF / EF lenses will allow you to use a teleconverter / extender.
They come in different magnification factors, such as 1.4x and 2x allowing photographers to extend their reach and capture distant subjects without the need for a new lens. Canon RF and EF extenders are compatible with many Canon RF and EF lenses, and they provide seamless communication between the lens and the camera for accurate autofocus and exposure control. However, it's important to note that extenders can affect image quality by reducing sharpness and increasing chromatic aberration, so it's important to use them wisely and only when necessary.
