It is headquartered in Ōta, Tokyo, Japan in 1937.
Canon introduced a field zoom lens for television broadcasting in 1958 and in 1959 introduced the Reflex Zoom 8, the world's first movie camera with a zoom lens.
It has two variable magnification lens groups, which are moved by independent cams. Moreover, it was the first zoom lens with an epoch-making 4x zoom and the fastest f/1.4 lens speed at the time. This lens was developed by Dr. Keizo Yamaji, who later became the president of Canon Inc., and so this kind of lens design was called the “Yamaji type.” It became the most popular zoom lens type for movie cameras.
This camera had a single-lens reflex viewfinder with a split-image rangefinder and electric exposure meter. This was the first Canon movie camera equipped with a zoom lens, and it became very popular. It also had a detachable trigger grip.
