Taisei Optical made a strategic decision to specialize in developing telephoto lenses, releasing its first lens, 135 mm (Model #280), in 1958. The lens was branded Tamron, to honor its designer (Tamura Uhyoue), and used the T mount system, making it adaptable to bodies from multiple camera manufacturers. It was bundled with a dedicated 1.67× teleconverter. Taisei continued to develop the interchangeable mount, releasing the Adapt-A-Matic (アダプトマチック) series starting in 1969 with the 70~220 mm (Model PZ-30Au), which added automatic diaphragm coupling capability, followed by the Adaptall (アダプトール) series starting in 1973. The Adaptall-2 series was introduced in 1979 and production continued until 2006. In the United States, Vernon Photographic Corporation (Mt. Vernon, New York) registered the trademark Edonar in 1967 for lenses sold under its own brand. Some Edonar lenses were built by Taisei Kogaku, as engraved on the lens.
