Riken Ricohflex Model IV

The Ricohflex Model IV, produced by the Japanese company Riken (later renamed Ricoh), represents a typical mid-20th century consumer twin-lens reflex (TLR) camera. Like many similar models of its era, it likely featured a waist-level viewfinder with a ground glass screen for composing images and a coupled rangefinder focusing system, standard for TLR designs. The camera would have been constructed primarily of metal and bakelite, designed for reliability in everyday use rather than high-end precision, utilizing a leaf shutter system and accepting 120 roll film to produce square negatives. As part of Ricohflex line, it embodies the company's early efforts to provide functional, accessible photography tools to the Japanese domestic market and potentially export markets, focusing on straightforward operation and reasonable image quality rather than groundbreaking innovation.
