Enables Closer Focusing. These extension tubes let your lens focus more closely than its set minimum focusing distance. This means you can use them to essentially convert any lens to a macro lens without compromising its original optical quality. These tubes are compatible with almost any Canon lens.

Three Tubes. The Kenko Extension Tube Set for Canon comes with 12mm, 20mm, and 36mm tubes that you can use individually or in any combination for macro work.

Retains Autofocus. These tubes let you retain autofocus when the lens’s effective aperture stays at f/5.6 or brighter.
