Orion Seiki Sangyo began in 1947 and entered the 35 mm SLR field with the Orion T in 1955. The early name change from Orion Camera to Miranda Camera records a developing company identity, not an unrelated badge; the first production cameras established the mechanical platform that later carried the Miranda name.

The Orion T and early Miranda T series established the outer Miranda bayonet alongside an inner 44 mm threaded mount. The paired interfaces accommodated automatic-diaphragm and preset lenses, accessories, and adapters. This physical arrangement remained the defining compatibility boundary of the original Japanese Miranda SLR system.

A, B, C, D, and DR models brought lever winding, evolving mirror and screen arrangements, and a broader market range. Their differences are more than decorative in some cases, but the surviving model record is strongest at family level; individual production revisions need manual and specimen confirmation before further splitting.

Automex bodies combined automatic diaphragm operation with an external arm that communicated the selected aperture for metering. Selenium-meter Automex I and II models were followed by the CdS-equipped Automex III, creating an upper technical line whose MEX-REX lenses must be identified by their coupling hardware as well as focal length.
Miranda sold the F, FM, G, GT, Fv, and FvT alongside the Automex line. The G manual shows the intended system clearly: automatic bayonet lenses, preset lenses on the inner thread, and adapters on either interface. Its interchangeable screens and large mirror made the G a particularly flexible expression of the design.

Allied Impex's ownership connected the Miranda and Soligor distribution stories, and many Miranda-marked optics were sourced through Soligor. The relationship helps explain repeated lens families and badges, but it does not prove a single optical factory. Supplier attribution remains a specimen-and-document question for each lens generation.
Sensorex brought CdS through-the-lens metering behind the mirror while retaining finder continuity with Automex bodies. Sensorex C and Sensorex II refined the line. Mechanical bayonet fit continued, but metering behavior depended on lens-generation coupling, making a camera-and-lens pair more informative than either engraved name alone.

Sensomat, Sensomat RE, RS, and RE-II bodies offered a parallel stop-down-TTL or nonmetered route through Miranda's late period. This was not a simple replacement for Sensorex: it was an overlapping platform with its own meter operation and, in the RE-II, compatibility with later EC-lens full-aperture metering.

The Sensorex EE introduced a new internal aperture-information method for E lenses, and the EC series made the late lineup more compact. E and EC lenses can mechanically work across much of the system, but their full metering communication is generation-specific. The change marks a late, serious effort to modernize Miranda automation.
Miranda added the fixed-lens Sensoret, M42-mount TM variants, the electronic dx-3, and scientific Laborec bodies as the original SLR line approached its end. These branches require separate system boundaries: the TM's M42 interface and Laborec's specialist fittings are not interchangeable with the core Miranda bayonet system.

The EE-2 and dx-3 sit at the end of original Miranda camera production. Secondary histories place the manufacturing stop at the end of 1976 while stock continued through distribution afterward. The evidence supports an end-of-manufacture distinction; it does not make every later sale or repair a new factory-production event.
In the 1980s the Miranda name appeared on products sold by the British retailer Dixons, commonly associated with Cosina manufacture and Pentax K mounts. This is a trademark and distribution afterlife, not continuity of the Japanese Miranda bayonet/M44 factory system. The changed mount is a practical identification safeguard.
Dated in the sources as “1980s”. Decade wording normalized to its full calendar span for scaling.
