Sanyou 三友 PT-1

The 三友 PT-1 by Sanyou is a basic 35mm rangefinder camera designed for the consumer market. It represents a typical mid-20th-century Japanese or Asian-produced compact camera, likely manufactured in the 1950s or 1960s during the boom of affordable 135 film cameras. Its core specifications—a rangefinder focusing system for accurate framing and a simple B,1"-1/250" focal-plane shutter—were standard for its era and class, providing reliable performance for everyday snapshots and amateur photography without significant mechanical complexity or premium features.
