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.
I bought this camera on eBay for $10. It is slightly bigger and heavier than I expected but does not feel bulky. Instead it feels solid and well built. The exposure system is very easy to use but the rangefinder focusing is not very bright, making it hard to see in low light. The camera is focused by aligning a diamond in the center of the viewfinder. When the image is lined up, the picture is in focus. The battery it takes, a 5.6V PX32 is not available anymore, but two batteries equalling the original voltage fit into the battery compartment without any hassle, making it very easy to find and install a replacement.
