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. The back is locked by a knob surrounding the tripod mount, at the centre of the bottom plate.

Revision as of 21:45, 13 October 2006

Template:127 Japan The Letix is a 4×4cm format camera, using 127 film, made by Asahi Kōgaku Kōgyō from 1940 to 1942.[1] This company was a sub-company of Riken (today Ricoh). At about the same time, Riken Kōgaku Kōgyō was making the Roico, another 4×4 camera.

Description of the body

The Letix has a bakelite body, like 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. It is written LETIX in some examples,[2] and Letix in advertising pictures.[3] At least one example is 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. The back is locked by a knob surrounding the tripod mount, at the centre of the bottom plate.

The Kraft by Ehito Kōgaku Kōgyō is very similar to the Letix, but with a metal body instead of bakelite. It is unknown if the two cameras are related, or if Ehito simply copied the Letix.

Evolution

In an advertisement dated October 1940[5], the Letix is 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 is K.K. Kaneki Shōten (株式会社カネキ商店). In an advertisement dated August 1941[6], the Letix is offered with the same equipment for ¥55 by the distributor Kawara Shashinki-ten (河原写真機店).

Examples of the Letix have been observed with this lens and shutter combination. 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 variant of the Letix has been observed, with an everset shutter by Neumann & Heilemann, giving 5–250, B, T speeds. The lens is reported as an Helios Anastigmat 50/4.5 and the shutter as a Perfect. The shutter plate is black, has the NH logo on the right (for Neumann & Heilemann) and two screwed black plates, one at the top marked Neumann & Heilemann and the other at the bottom wearing the aperture scale.[7] The same lens has been observed on an example of the Seica.[8]
