This article is about the spring-folder camera made in the 1940s and 50s. For the 1990s camera, see Mamiya 6.

The Mamiya Six is a series of 6×6 folders with a coupled rangefinder, made by Mamiya from 1940 to the 1950s. All of them are focused by moving the film plane, rather than the more common front-cell focussing of other folders of the time.

Evolution

The Mamiya Six I, II and III were wartime and immediate postwar models which had both eye-level and waist-level finders. The coupled rangefinder was combined with the eye-level finder. As a result, there were three windows at the front of the top housing. The Mamiya Six III added an exposure counter with double exposure prevention.

With the Mamiya Six IV, introduced in 1947, the waist-level finder disappeared. It remained the sole model until 1953. The Mamiya Six V added the dual 6×6 and 4.5×6 format capability, with an exposure counter functioning with both formats. The Mamiya Six K was a simpler model, with film advance via red windows.

In 1955, the Mamiya Six IVB introduced a squarer body design, easily recognized by the square rangefinder window. Its features were similar to the model IV. The Mamiya Six K2 was similar to the model K with the new body. The body design was slightly modified again for the Mamiya Six IVS and simpler Mamiya Six P.

From 1955, the Mamiya Six Automat and the later Automat 2 added a coupling between the shutter cocking and the film advance.

Given the quite erratic nature of model numbering that occurred over the years, the chronology of the thirteen major Mamiya Six models is set out in Table 1. The characteristcs of the individual models, as well as the variants within these models, are described further below. If in doubt about some of the features mentioned in the type descriptions, please refer to the visual documentation of the critical elements which provides a dichotomous key as well as a series of illustrations showing the model-specific details.

Pre-War and War-Time Models

The first model was released in December 1940. Until the end of the World War II, the Mamiya Six was significantly modified at least three times: first in early 1941 (model Ia) with two additional models introduced in the next two years. Erratically, model III was released in 1942 (according to the official Mamiya history website[1] before model II (1943). All pre-war and war-time models have a set of range finder windows and a seperate waist-level brillant-type viewfinder, resulting in three windows at the front. All units have a single red film frame counter window counter on the back with a horizontal slider. The pre-war and war-time models were all 6x6 format cameras.

Mamiya Six I

The camera was advertised in September 1940[2] and released in December 1940 at a price of ¥248[3]

Technical details

All units are covered with leatherette with exposed chrome top housing and bottom-plate The camera has a slightly larger waist level viewfinder (12 x 12 mm) than the subsequent models. The round viewfinder window on the front has a serrated edge to it, while it is smooth on the later models. Model I the only Mamiya Sox design with small eyelets for a neck strap. Other charcatreostics are: a solid knurled film winding knob, a raised button (on the top plate) to release the front door; indicator arrow next to the film counter is a pointed arrow with a thin tail; the shutter release button has a rounded top.

Dimensions:

140 x 103 x 51mm (closed), weight 780g.

Lens and shutter combinations:

Interestingly, Mamiya offered purchasers to bring their own lenses, which would be installed in the '0' shutters. This resulted in a range of known shutter combinations.

Mamiya Six Ia

The next iteration, publicised in January 1941[5] saw the use of a larger shutter, which required the redesign of the strut system. [6] The camera sold for ¥298.

Technical details

All units are covered with leatherette. The camera has a slightly larger waist level viewfinder (12 x 12 mm) than the subsequent models. The film respool knob is a solid knurled knob. The indicator arrow next to the film counter is a pointed arrow with a thin tail

Dimensions:

Mamiya Six II

The camera was introduced in ¶¶ 1943.[8] Even though numbered Mamiya II, this is in fact the third model to have been introduced. Like the Mamiya Six Ia, this model has a red double exposure warning pane in the rangefinder window. The Mamiya Six II is essentially a Mamiya Six III design without the flash contacts. Thus, in common it also has the slightly smaller waist level viewfinder (10 x 10 mm) and a smooth rim to the central viewfinder window.

Technical details

Like the Mamiya Six III from which this model is dereived, the Six II has a smaller waist level finder (10 x10 mm) and the dimpled shutter release button.

The camera was introduced in ¶¶ 1942[9] The camera was fitted with a double exposure warning system, comprised of a small transparent, red coloured half-pane that would appear in the rangefinder window.

The Mamiya Six III has a smaller waist level finder (10 x10 mm) window on the top late, while the round viewfinder window on the front has a smooth edge. The shutter release button now has a slight depression (dimple) in the top.

PAGE 2 Mamiya Six Design Variations

This page provides a visual overview over those design elements of the Mamiya Six cameras that permit an accurate identification of the various variants.

Dichotomous Key (model Identification)

The Mamiya Six comes in a bewildering range of variants. The dichotomous key provided below provides an avenue at identifying the types of Mamiya Six. Given the confusing similarity of models and variants, it is recommended that you follow the steps, rather than scanning for criteria. When you have identified your model, click on the model name to see a full description. If you are unclear about one of the criteria, either click on the name or scroll down to the bottom of the page for visual identification guides.

Lenses and Shutters

The Mamiya Six was manufactured in a wide range of lenses and shutters. That holds particularly true for the pre-War and War period, when prospective buyers could even bring in their own shutters and lenses to be fitted.
