(Wikipedia info) Yashima Seiki Company was founded in 1949, with 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 6×6 cm 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 Tomioka Optical Works, beginning a relationship that would last for many years.
Yashica found it difficult to gain market acceptance with its proprietary SLR lens mount and redesigned its SLR camera line in 1962 to accept the Contax/Praktica M42 lens mount.
August 1968, Yashica acquired its lens manufacturer, the Tomioka Optical and Machine Manufacturing Co., Ltd. (later renamed the Tomioka Optical Co. Ltd. By this time, Tomioka was one of the largest and most reputable lens manufacturers in Japan.
(From this era is where my lens is from) In 1968, Yashica introduced the TL Electro-X 35mm single-lens reflex (SLR) camera and produced it until 1974. It had a screw thread lens mount, the M42 lens mount, for its interchangeable lenses. (Wikipedia info ends).
This lens is a more collectible item than for everyday use even though the image quality is good, a long lens like this can only be used on a sunny day in my opinion and the closest focusing is 9 meters and that is just too far for me, but I’m happy that have a rear fifty-year-old lens in my lens collections.
