Tamron was founded in 1950, and in 1957, the 135mm f/4.5 lens was developed for 35mm SLR cameras. The world's first interchangeable mount system, the 'T' mount, was developed for use with interchangeable lens cameras.
The main plant was situated in Hasunuma, Omiya-city, and in 1959 Tamron is registered as a trademark. The Industrial Optics Division is started the following year, in 1960.
Broader use of film lenses was initiated in 1961, partly through Tamron's mass production of 95-205mm f/6.3 telephoto zoom lenses for general consumer use, the first in the industry.
A branch office was established in New York in 1969, and Tamron's presence as a worldwide brand was realised. The Tamron 12.5-75mm C-mount 6x zoom lens was then released in 1971, selling over 50,000 units.
Tamron launched the 'Adaptall' lens range in 1976, which introduced an exclusive quick-focus system and built-in lightweight macro-mechanism.
The well known SP series was launched in 1979, and in 1992, Tamron received its first industry awards, with the SP AF 35-105mm f/2.8 being crowned European Lens of the Year. The following year, in 1993, Tamron received the same accolade for the AF 28-200mm f/3.8-5.6 lens.
Tamron UK was established in 1995, and in 1998, Tamron went on to sell 1 million units of the 28-200mm lens.
Today, Tamron is one of largest lens manufacturers in the world.
