Pax Ruby Analogue camera

Pax Ruby (Yamato Koki) – A Rare Japanese "Subminiature-Style" 35mm Rangefinder
The Pax Ruby, manufactured by Yamato Koki in the late 1950s, is a fascinating example of the "Leica-style" 35mm rangefinder craze that swept through Japan post-WWII. Despite its diminutive size—often mistaken for a subminiature camera at first glance—the Pax Ruby is a full-featured 35mm film camera. It is celebrated by collectors for its surprisingly high build quality, bright coupled rangefinder, and sharp optics. This "Ruby" edition is particularly prized for its refined aesthetic and the distinctive red logo on the front plate, representing a high point for the boutique manufacturer Yamato.
