Not all fast lenses came from the lens giants. Other slipped under the radar. A good example is the Harigon 58mm f/1.2. It was made by Taika, which in reality was a export brand of Taisei Kōgaku Kōgyō K.K., the company which would later become Tamron (in all likelihood, Taika was a simpler and easier brand to remember than the company name). It was also sold as a Tamron lens.

The lens was introduced in 1960, for the US market. The design was likely along the lines of the Zunow 5.8mm f/1.2, which is a itself is scarce as hen’s teeth.

Optical Science has produced this all-new Taika Rare Earth Lens, Eight hard coated complex elements of fabulous precision are responsible for its superb color correction and sharpness beyond reproach. The Taika Harigon has a dignified beauty – ebony black with colored engraved scales. A “Rolls Royce” in performance and appearance. You will be proud to own it, proud to show it and proud to exhibit its beautiful pictures.

Apparently it was available in Exakta mount, in addition to Praktica M42, and Miranda. In the early 1960s it was advertised as the standard lens on the Exa II camera for US$198.50 (from Seymour’s, NY). Interestingly the lens itself sold for US$169.50. By the time the Adapt-A-Matic Lenses appeared in the late 1960s, the 58mm lens had disappeared. There seem to be very few on the market today.
