Production of interchangeable EF lenses, for Canon EOS-series autofocus SLRs, began in 1987 at Canon Inc.’s Utsunomiya Plant, and has since expanded to a total of four production facilities.
Production of EF lenses surpassed the 10 million mark in 1995, doubled to 20 million units in 2001, hit 30 million in 2006, with the 40-millionth lens made in 2008. Manufacturing reached 50 million in 2009, followed by the 60-million mark in January 2011, and the 70-million mark in October the same year.
Last year, the EF series added the EF Cinema Lens series for digital cinematography and the EF-M series for mirrorless camera.
As a result, Canon’s current EF lens lineup consists of 76 models.
