The Konica Koniflex is a twin-lens reflex camera manufactured by Konishiroku (marketed under the Konica brand) from 1953, using 120 roll film to produce 6x6 cm square negatives. It is fitted with a **Hexanon 85mm f/3.5** taking lens paired with a matched viewing lens, arranged in the classic TLR configuration with a waist-level reflex finder and ground-glass screen. The Koniflex was Konica's bid to enter the established TLR segment dominated by Rolleiflex and the growing number of Japanese competitors such as Yashica and Minolta.

By 1953 the Japanese TLR market was intensifying rapidly. Yashicaflex had launched in 1953, the Minolta Autocord was in development, and Rolleiflex remained the aspirational benchmark. Konishiroku, having established its Pearl folder line in the postwar years and building credibility under the Konica brand for its 35mm cameras, introduced the Koniflex to capture the professional and serious-amateur 6x6 segment. The Hexanon 85mm f/3.5 lens used in the Koniflex became associated with the higher-end optical quality Konica was developing, distinct from the Hexar triplets used in the Pearl folders. Production continued for a limited period and the camera was not as widely distributed as competitors like the Yashica-Mat or Minolta Autocord.
The Koniflex occupies a small but distinct place in Konica's history as the company's only significant TLR offering. While Konica ultimately concentrated its medium-format development on the folder and, later, the Koni-Omega press cameras, the Koniflex shows the breadth of the company's 1950s ambitions. The Hexanon glass in this camera is of particular interest to collectors, as the Hexanon name would go on to significant prestige in Konica's 35mm SLR line. As a camera the Koniflex is less widely serviced and documented than its Yashica or Minolta counterparts, making it a curiosity rather than a workhorse choice.
