Tamron Lens Reviews
Tamron Co., Ltd. (株式会社タムロン Kabushiki-gaisha Tamuron) is a Japanese company manufacturing photographic lenses, optical components and commercial/industrial-use optics.
The name of the company came from the surname of Uhyoue Tamura who was instrumental in developing Tamron's optical technologies. It was only on the company's 20th anniversary that the name was changed to Tamron (from Taisei Optical).
