Orion Seiki
Est. 1947
Orion Seiki
Orion Seiki Sangyo Y.K. was a Japanese precision-camera company founded in the early postwar period by engineers Akira Ogihara and Shintaro Otsuka. It began with repairs, camera accessories, and optical-mechanical adapters before creating the Miranda single-lens-reflex camera line. Within Leica rangefinder history, Orion Seiki is associated with the Universal Supreme 50mm f/3.5 collapsible LTM lens, conversion accessories, and equipment designed to extend the usefulness of Leica screw-mount cameras.
History
Founding / Early Years
Sources place the company's formation in 1946 or 1947, with 1947 commonly used for the start of Orion Seiki Sangyo. Its founders had engineering backgrounds connected with Japanese naval or aeronautical work. The early workshop repaired and modified cameras and developed specialist accessories at a time when imported equipment was difficult to obtain in Japan.
Market Entry
Orion Seiki first reached photographers through products such as the Coupler, which allowed certain Contax or Nikon rangefinder lenses to be used on Leica screw-mount cameras while retaining rangefinder operation, and the Mirax reflex housing. It also marketed Supreme lenses and Focabell bellows equipment. The collapsible Universal Supreme 5cm f/3.5 is documented in LTM form, but available sources do not conclusively identify the optical glass supplier or establish that every Supreme lens was manufactured entirely in Orion's own facilities.
Expansion / Modern Period
The company developed the Phoenix 35mm SLR prototype in 1954. It changed its name to Orion Camera K.K. in 1955 and introduced the Miranda T, one of Japan's early pentaprism SLR cameras. In 1957 it became Miranda Camera K.K. Miranda later relied heavily on outside lens suppliers and ceased operations in 1976. Orion Seiki therefore marks the formative stage of the Miranda business rather than a continuing modern lens brand.
Product Lines
LTM Lenses and Adapters
Products included Universal Supreme and Supreme lenses, the Coupler adapter system, and accessories for Leica-style rangefinder cameras.
Reflex and Close-Focus Equipment
The Mirax reflex housing and Focabell bellows anticipated the company's later emphasis on interchangeable-lens SLR equipment.
Miranda Cameras
The Phoenix prototype and Miranda T established the product direction followed under the Orion Camera and Miranda Camera names.
Technical Characteristics
| Feature | Description |
|---|---|
| Early specialty | Precision adapters, repairs, bellows, and reflex accessories |
| Reference lens | Universal Supreme 50mm f/3.5 Collapsible |
| Lens mount | Leica M39 screw mount on documented examples |
| Focusing | Intended for coupled rangefinder use, condition and calibration should be checked |
| Optical manufacture | Exact supplier attribution for early Supreme lenses remains uncertain |
| M-mount use | LTM lenses can be fitted with a suitable LTM-to-M adapter |
Market Reception
Orion Seiki is historically important less for a large range of Leica lenses than for its inventive postwar accessories and its evolution into Miranda. Universal Supreme lenses are scarce and of interest to collectors of Japanese LTM equipment, while the Coupler and Mirax demonstrate the company's engineering-led approach. Its later reputation is dominated by Miranda SLR cameras, making Orion-branded rangefinder equipment a comparatively specialized collecting field.
