Attaching this high performance Extender to a 135mm or longer lens, or to the EF 70-200mm f/2.8L, boosts the focal length by 2 times. With seven elements in five lens groups, it preserves the prime lens image quality.

With the Extender attached, the f-number decreases by two stops. Autofocusing is possible with lenses whose maximum aperture is f/2.8 or faster.

  • EF135mm f/2 L USM
  • EF180mm f/3.5 L MACRO USM
