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.[1] At about the same time, Riken itself was also making the Roico, an all-metal 4×4 camera.

Description of the body Edit

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,[2] and as Letix in cursive style in advertising pictures.[3] At least two examples are known with the body marked Retix.[4] 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.

Relation with the Kraft Edit

The early version of the Kraft made by Echt from about 1940 is very similar to the Letix, but its main body is made of metal instead of bakelite. The two cameras have the same viewfinder, exposure counter, advance knob, accessory shoe and telescopic tube, and their top housing is only slightly different. Those parts were probably supplied by Echt to Asahi Kōgaku Kōgyō, which was probably specialized in bakelite cameras — the reverse seems less likely.

Commercial life Edit

The earliest known advertisement for the Letix is in Asahi Camera October 1940.[5] It mentions the manufacturer Asahi Kōgaku Kōgyō and the distributor Kaneki Shōten, and offers the camera 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. Other advertisements in the same magazine dated November 1940 (by Asahi Kōgaku Kōgyō) and August 1941 (by Kawara Shashinki-ten, another distributor) list the Letix with the same lens and shutter combination for ¥55.[6]

The camera appears 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.[7] The last known mention of the camera is in a column of the February 1942 issue of Asahi Camera.

Surviving examples Edit

Examples of the Letix have been observed with the Ukas lens and 25–150 speeds.[8] 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.[9] It has a 5cm f/4.5 lens reported as a Helios Anastigmat, probably a three-element lens made by Tōkyō Shashin Kōgaku.[10] 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.
