Like the rest of the Canon Super Telephoto lenses, the 600 IS L is compatible with the Canon EF Extenders. Image quality with the Canon EF 1.4x Extender mounted is reasonable - especially for an 800mm f/5.6 IS lens. As always, this extender adds CA (Chromatic Aberration), adds barrel distortion, reduces contrast/sharpness and slows autofocus.

Extenders, also often called teleconverters, are optical accessories that attach to the rear end of a lens to increase the focal length. The two most common varieties are 1.4x and 2x extenders, though Nikon also makes a 1.7x version as well. As you’ve probably guessed, the number represents the factor by which the focal length gets multiplied.
