Since its founding, Canon has sought to create the world's finest cameras. The components essential to this quest today are the lens, which corresponds to the human eye; the image sensor, which corresponds to the retina; and the image processor, which corresponds to the brain—all of which are developed in-house. As such, Canon-proprietary technologies deliver exceptional levels of imaging performance. In addition, the company celebrated a world's first manufacturing milestone as production of our EF interchangeable lenses surpassed the 100-million-unit mark. Embodying Canon's extensive optics know-how, these lenses support a diverse range of imaging expression, opening the door to new possibilities and new discoveries in the world of photography. The evolution of photography that Canon optical technologies has made possible to date represents the very history of Canon itself. We continue to tackle new challenges in photographic expression to provide users with ever-higher levels of expressive freedom and beauty.
