Capturing the visual moment of life, shaping it to a form of existing object, and preserving it over a period of time as an evident of the moment…… this chain of process was one of the critical innovations of human beings and has always been the primal attention of manufacturing industry. Inheriting the technology of photography from Europe and America in mid 1800’s, Japan has been dedicating efforts to the production of camera and optics ever since. The manufacturing of optics requires long term process from glass material, and the entire process is consisted of high level of accuracy. The natural-born spirit of manufacturing, that is gifted to people in Japan, has been supporting the extraordinary enthusiasm and patience for manufacturing, and that enabled to keep the constant effort to produce high-quality optics. The perfectionism dwelt in the entire process from designing, grinding, assembling up to quality control and inspection, enabled Japan to achieve the prestige in optical industry.
