Miyamoto Seisakusho was founded in 1948 as a metal processing factory. We specialize in precision machining, started manufacturing macro rings for single-lens reflex cameras for export around 1973, and have supplied macro rings to a German camera manufacturer on an OEM basis. Manufacturing of macro rings started with those for the M42 mount, and the number of compatible mounts has since increased.

We want to make a high-precision mount adapter that can obtain the same image (light) as the original photo even when shooting with a lens and camera body from different companies using our mount adapter. Our brand name expresses the enthusiasm of such a manufacturer.
