Overview
This is a classic Japanese 120 medium-format Twin-Lens Reflex (TLR) camera produced by Chiyoda Kōgaku (later Minolta). Featuring the distinctive script 'Minolta' nameplate and a Chiyoda emblem on the viewfinder hood, it represents the golden age of Japanese mechanical camera engineering.
Story
Post-war Osaka saw Chiyoda Kōgaku rivaling German camera giants like Rolleiflex. Built with remarkable mechanical precision, this TLR brought professional medium-format photography into the hands of everyday enthusiasts.
Maker / Origin
Founded in 1928 by Kazuo Tashima, Chiyoda Kōgaku became one of Japan's most innovative optical companies, pioneering built-in light meters and autofocus before rebranding permanently as Minolta in 1962. Their cameras were celebrated for combining accessible pricing with exceptional Japanese glass.
Condition & Value
Cosmetically very clean with intact leatherette, crisp metal trim, and attached shutter release cable; lens caps are present. Shutter timing and optical clarity inside the lenses remain untested, which dictates top-end value. Values depend heavily on shutter accuracy, lens clarity (absence of fungus/haze), and cosmetics.
