Kiron

Kiron Corporation was a subsidiary of Kino Precision Industries, Ltd., a Japanese manufacturer of photographic lenses. Kiron was based in Carson, California, operating in the 1980s primarily as the United States distributor of Kiron lenses, which were offered in a variety of mounts compatible with many popular 135 film manual focus single-lens reflex camera systems. Kino Precision was founded in 1959 and by the time Kiron was organized in 1980, Kino Precision had gained experience manufacturing lenses sold by Vivitar, including several marketed under the latter company's premium "Series 1" line.
