The Supreme lenses were made by Orion, predecessor of Miranda Camera.

Lenses in Leica screw mount

Universal Supreme 5cm f/3.5

The Universal Supreme 5cm f/3.5 is only known from an article by Orima Isamu in Kurashikku Kamera Senka.[1] In this document, it appears on a viewfinder-only Chiyoca 35, which was passed to the author by Ogihara Akira (荻原彰), founder of Orion. No other example is known, and the lens was perhaps a prototype. The serial number is 510418 — the two first digits might indicate that the lens was produced in 1951.

The lens is probably coupled to the rangefinder but this is not confirmed.[2] The lens owner reports that it has three elements, judging from the number of reflections;[3] this is however strange on a 5cm f/3.5 lens in Leica screw mount, where one would expect a Tessar formula with four elements.

The barrel is collapsible and has an all chrome finish. The rear part with the focusing ring is inspired by the Leitz Elmar 5cm f/3.5. Focus is driven by a tab with an infinity lock. The focusing scale is engraved in metres and goes down to 1.25m or closer.[4] The front part is inspired from the Elmar 5cm f/2.8, and has the aperture scale on the side, graduated from 3.5 to 16. The lens has two screw threads for filter or hood attachment: an inner one around the lens bezel and an outer one. The lens bezel is engraved Universal Supreme 1:3.5 f=5cm No.xxxxxx in black on a chrome background.

To be continued.

Notes

  1. Orima, pp.104–6 of Kurashikku Kamera Senka no.24.
  2. The lens was found on a viewfinder-only camera, hence the doubt.
  3. Orima, pp.105 of Kurashikku Kamera Senka no.24.
  4. In the available pictures, the focusing tab perhaps hides the minimum distance.
