Detailed and competent information about Yashica rangefinders:
Yashica MG-1 (1975)
The MG-1 was released in 1975. It is a leaf-shuttered 35mm coupled-rangefinder camera with aperture-priority automatic exposure. The MG-1 has a 45mm f/2.8 Yashinon lens.
This is one of the "Last Samurais" before the "Plastic Age". The Yashica MG-1 is a "full size" rangefinder. Some wouldn't like its automatic functions but its a feature which makes it easy to use. The almost total lack of manual control is no doubt a limitation. It is achieved with a higher cost. The Yashica MG-1 is however designated to a person who did not put value on such oddity.
