Letix

The Letix is a Japanese camera taking 4×4cm on 127 film and partly made of bakelite. It was produced from 1940 by Asahi Kōgaku Kōgyō, a dependent company of Riken Kōgaku Kōgyō (today Ricoh), and was a remote evolution of the Olympic cameras. At about the same time, Riken itself was also making the Roico, an all-metal 4×4 camera.

Description of the body

The Letix has a bakelite body, as the Olympic, but the lens and shutter assembly is mounted on a metal telescopic tube. The name of the camera is moulded in the front of the body. The name appears as LETIX in capital letters on many examples, and as Letix in cursive style in advertising pictures. At least one example is known with the body marked Retix. An explanation for that funny mistake is that the Japanese phonology does not distinguish between the "l" and "r" letters.

The Letix is covered by a top housing except the space around the advance knob, at the left end of the top plate. The advance knob itself is quite thick, and the camera is equipped with auto-stop film advance. The tubular optical finder is a distinct part, centred above the top housing, and there is an accessory shoe on the right end. Between the shoe and the finder is an exposure counter made of a fully exposed disc engraved from 1 to 12. This device was necessary because at the time, the film paperback was not marked for 4×4cm pictures. Between the finder and the advance knob there is a button that perhaps unlocks the auto-stop advance device. The back is removable together with the bottom plate, and has a single red window to set the first exposure, protected by a horizontally sliding cover. The back is locked by a knob surrounding the tripod mount, at the centre of the bottom plate.

The Kraft made by Ehito or Ishii from 1941 to 1943 is very similar to the Letix, but it has a metal body instead of bakelite. The early version of the Kraft has the same viewfinder, exposure counter, advance knob, accessory shoe and telescopic tube as the Letix, and the top housing is only slightly different. The two cameras are surely related, but it is not known if the maker of the Kraft was a subcontractor of Asahi Kōgaku Kōgyō that made the metal parts of the Letix from the beginning or if it bought the design and some toolings or parts to Asahi Kōgaku Kōgyō to sell a modified version with a metal body.

Evolution

In an advertisement dated October 1940, the Letix was offered with a front-cell focusing Ukas Anastigmat 50mm f/4.5 (a lens equipping many models of the Olympic) and a shutter giving 25, 50, 100, 150, B, T speeds. The distributor was K.K. Kaneki Shōten (株式会社カネキ商店). Other advertisements dated November 1940 (by Asahi Kōgaku Kōgyō) and August 1941 (by the distributor Kawara Shashinki-ten) offered the Letix with the same lens and shutter combination for ¥55.

The camera was mentioned in the official list of set prices compiled in October 1940 and published in January 1941, under the names "Letix I" (¥60) and "Letix II" (¥95), with no further details.

Examples of the Letix have been observed with the Ukas lens and 25–150 speeds. The shutter plate has decorative patterns, is marked Letix at the top, has an AKK logo on the right (surely for Asahi Kōgaku Kōgyō) and the aperture scale at the bottom. The speeds are written on the rim in the following order: T, B, 150, 100, 50, 25. The shutter is everset, and it is probably the same as mounted on the Olympic cameras.

Another version of the Letix has been observed, perhaps corresponding to the Letix II. It has a 5cm f/4.5 lens reported as a Helios Anastigmat, probably a three-element lens made by Tōkyō Shashin Kōgaku. The shutter is an everset Perfect (5–250, B, T) by Neumann & Heilemann, in #00 size with the early shutter plate design (see Perfect). (A similar lens and shutter combination is found on the Seica.) The known pictures perhaps correspond to a single surviving example; it is also distinguished by the reduced frame around the viewfinder window.
