A totally new 7-element optical design for this version II extender means superior image quality combined with a doubling of the lens' marked focal length (with a two-stop reduction in effective aperture). Compatible with the same lenses as the 1.4x II extender, the EF 2x II still allows autofocus with any EOS body when used with a lens f/2.8 or faster.
It features an improved anti-reflection internal design and weather-resistant exterior, including seals at its front and rear lens mounts, that match those on Canon's newest professional lenses and camera bodies.
