Yashica was a Japanese manufacturer of cameras. The trademark rights of Yashica are now owned by Hong Kong-based MF Jebsen Group. In 2015, trademark rights were transferred to Yashica International Company Limited and appointed 100 Enterprises International Group Co. Limited as Yashica Global Sole Agent.
The company began in December 1949 in Nagano, Japan, when the Yashima Seiki Company was founded with an initial investment of $566. Its eight employees originally manufactured components for electric clocks. Later, they began making camera components, and by June 1953 had introduced their first complete camera, the Yashimaflex, a twin-lens reflex (TLR) medium-format camera designed for 6x6cm medium format film. While the Yashimaflex used lenses labeled Tri-Lausar, successive models used Yashikor and Yashinon lenses. All of these lenses were manufactured for Yashica by the Tomioka Optical Works, beginning a relationship that would last for many years. Late in 1953, Yashima Seiki Company became Yashima Optical Industry Company, Ltd.
In 1957, Yashima founded Yashica, Inc., a subsidiary arm in New York City to manage marketing efforts in the United States. 1957 also marked the introduction of a popular new TLR camera series, the Yashica Mat line., as well as an 8mm cine movie camera. During the next year and a half, Yashima continued to grow, with 1,982 employees by 1958. Later in 1958, Yashima changed its name to Yashica Company, Ltd, when it acquired the Nicca Camera Company, Ltd. The Nicca acquisition was fortuitous, as the designs acquired assisted Yashica in expanding its product line into advanced 35mm rangefinder cameras.
The Yashica Pentamatic, an advanced, modern 35mm Single Lens Reflex (SLR) camera with a proprietary bayonet-mount, automatic diaphragm (offered only with the Auto Yashinon 50mm/1.8 lens), and interchangeable lenses, was introduced in 1959. As before, Yashica continued to source its lenses from the Tomioka Optical factory.
Around 1959–1960, Yashica acquired the assets of the bankrupt Zunow Optical Industry Co. Ltd. Though a small company, Zunow had become known for limited production of a very advanced 35mm SLR camera, along with several high-quality, fast 35mm camera and 8mm cine (movie) lens designs and a proprietary bayonet-mount lens system similar to that of Yashica Pentamatic. With the assistance of Tomioka Optical Works, Yashica adapted Zunow lens designs into its own 8mm turret cine (movie) cameras.
