Tokina Co., Ltd is a Japanese lens maker. The company was established in Shinjuku, Tokyo in May of 1950 as Tokyo Optical Equipment Manufacturing. Early lenses were marked with Tokyo Koki, a shortened version of the phonetic translation into English of the company's name, Tokyo Koki Seisakusho[1][2] (note that there is another company that used the English moniker Tokyo Koki.) The company was founded by former Nikon engineers as an OEM manufacturer and originally made lenses for other companies, such as Ponder and Best (later Vivitar). In the early 1970's the company began selling lenses under it's own brand name, Tokina.[3] In May of 1971 the company changed its name to Tokina Optical Co. Ltd. The company was later acquired by Kenko in March of 1999.[4][5]. Kenko also purchased optical glass manufacturer Hoya, whose glass was used by Tokina Optical. The combined company is now known as Kenko Tokina Co., Ltd. The US branches of the companies, Tokina Optical Corporation USA and Kenko Company USA had previously merged in 1993 to form THK Photo Products, Inc. The letters THK comes from Tokina, Hoya, Kenko.[6] With the latter Tokina was merged in 2011 into Kenko-Tokina.
