Rokkor was a brand name used for all Chiyoda Kōgaku Seikō and later Minolta lenses between 1940 and 1980, including a few, which were marketed and sold by other companies like Leica. The name was derived from the name of Rokkō (六甲山), a 932 metre (3058') high mountain, which could be seen from the company's glass-making and optics factory at Mukogawa near Osaka, Japan. The company's founder Kazuo Tashima wanted the name to symbolize the high quality in optics.

TC-1 is a luxury point and shoot camera that was produced by Minolta. It is a compact 35 mm clad in titanium, equipped with a G-Rokkor 28mm f/3.5 lens. The TC-1 was equipped with a high quality lens and body, similar to other luxury compacts produced during the Japanese bubble economy era, including the Contax T line, Konica Hexar, Leica minilux, Nikon 28/35Ti, Ricoh GR series, and Rollei QZ 35W/35T. Expensive when initially released in 1996 with a suggested retail price of ¥148,000, it was produced in small numbers and since then has become collectible.
