This 55mm f/1.4 Chinon lens came with a Chinon CX camera dating from c1976. I bought them on eBay for £37 in 2015. I only wanted the lens, which was made by the Tomioka company for Chinon, who sub-contracted all their lens needs during that period.
I photographed it using a Helios-44 58mm f/2 lens on a Canon EOS 30D camera. The Helios is even older, probably made during the 1960s. It is a preset lens; I had no experience of such technology until acquiring it. I got it on eBay attached to a Zenit-E camera.
