Hansa Canon Camera

 

A Description and Origin of the Hansa Canon - Canon Hansa Camera

 


Hansa Canon 1935

An early Hansa Canon manufactured in late 1935

 

The Hansa Canon Camera

 

The Home Page of canonrangefinder.org  described how Goro Yoshida, an engineer, in November 1933 with his brother-in-law Saburo Uchida (1899-1982) and with Takeo Maeda (1909-1977), established Seiki-Kōgaku Kenkyusho (Precision Optical Instruments Laboratory).

Their intention was to developed a 35mm rangefinder camera. They produced a prototype 35mm camera called the "Kwanon", but which was not commercialized.

From the "Kwanon" initial designs, Saburo Uchida with Takeo Maeda in 1934 and 1935 20 developed the camera which, with the suggestion of outside investors, became known as "Canon". After being equipped with a lens and lens mount described below, this first Canon camera was first produced in October 1935 and introduced to the Japanese market in February 1936. 1

The Hansa Canon - or Canon Hansa

 

This first camera with the name "Canon", developed in 1935 and introduced in Japan in early 1936 had the name "Hansa" on its top plate. It is generally referred to today as the "Hansa Canon" or sometimes the "Canon Hansa". I prefer the name "Hansa Canon" as being more descriptive.

 

Seiki-Kōgaku did not yet have camera sales ability. However, they had a contract with Omiya Shashin Yohin Co., Ltd. (Omiya camera and accessory shop) (大宮フォトサプライ). The owner of Omiya, Hikotara Noro had been one of those instrumental in changing the camera name from "Kwanon" to "Canon". Omiya Shashin Yohin Co., Ltd. used the marketing name "Hansa", and their Hansa trade name was engraved on the top of the camera.

The first Hansa Canon cameras produced in late 1935 used some components from the initial "Kwanon" prototype development cameras. The earliest Hansa Canon models had a depressed area around the pop-up viewfinder as did the Kwanon. The depressed area in fact was no longer needed, since the viewfinder was elevated by pressing a release button on the camera rear, rather than the photographer pulling the viewfinder up.

Another feature of the Hansa Canon inherited from the earier Kwanon model was the accessory shoe having semi-circular cut-outs in the accessory shoe retention bracket.

Each Hansa Canon had a lens focusing mount manufactured by Nippon Kōgaku, then the (only) Japanese manufacturer of camera glass and the producer of Nikkor branded lenses. This focusing mount design avoided the Leica focusing patent which had been issued in Japan 1. Under this patent, each Leica lens was fitted with its own helicoid focusing mount, which the photographer turned to focus the lens. The lens assembly then screwed directly into the Leica camera body. The Nikkor focusing mount avoided the Leica patent because focusing was done by the mount rather than by the lens itself.

 

Each Nikkor focusing mount had a number engraved on its base. Initially, this was engraved with the number and "Nippon Kogaku Tokyo"; later by the number alone.

These focusing mount numbers are the best way to identify individual Hansa Canon cameras. However, there was also a serial number stamped inside the base plate of each camera.

Peter Dechert 1 stated:

 

"Lensmount serial numbers are in fact the only way to individualize Canon Hansa cameras, which were assembled roughly in lensmount number sequence until 1939. Numbers stamped on the inside of the baseplates are design types, 1xxx had the central socket, while 2xxx and 3xxx had a socket at the camera's take up end."

 

Hansa Canon Camera Lenses

 

The Hansa Canon in fact could not have been introduced without sourcing a camera lens, which Seiki-Kōgaku did not produce. The Canon rangefinder needed lenses for the 35mm format, and Nippon Kōgaku was able to fulfill that need by developing a new lens. This was a new Nikkor 5cm f3.5 lens. Nippon Kōgaku produced the lens for Canon, as well as producing the focusing mount for the lens. Canon fitted the Nikkor 5cm f3.5 lens into a lens mounting tube or flange for insertion into the Nikkor focusing mount. Interestingly, the focusing mount with its locking mechanism in the Nikkor design closely resembled the design of the German Contax camera lens mount.

The optical company Nippon Kōgaku Kogyo - 日本光学工業株式会社 or "Japan Optical Industries Co., Ltd." had been created in 1917 23 during World War I, aided by the Imperial Japanese Navy and the Mitsubishi group. 20 Nippon Kōgaku were not yet making cameras themselves. The later famous series of 'Nikon' cameras was launched in 1948. From Canon's beginning, Nippon Kōgaku Kogyo provided the lenses for all Canon cameras until Canon's own lens production began in 1946-1947. 2

 

Initially, the Nikkor 50mm f3.5 lenses were supplied to Seiki-Kōgaku in metal tubes to which Seiki-Kōgaku would add the appropriate lens mounting flange for mounting into the camera. Early versions of these Nikkor lenses had f-stops selected on the lens front. In 1936, the marked f-stop progression was the earlier progression then in use: f3.5, f4.5, f6.3, f9, f12.5, f18.

 

These Nikkor lenses came first in black faces, which during 1936 and 1937 production did not have lens serial numbers on the lens bodies. In 1937, a white face Nikkor 5cm f3.5 lens was introduced which included lens serial numbers on the face.

During Hansa Canon production, no other accessory lenses were offered to be used with the camera.

 

Introduction of the Hansa Canon

 

Since Seiki-Kōgaku did not yet have its own camera sales ability, its contract with Omiya Shashin Yohin Co., Ltd. (Omiya camera and accessory shop) (大宮フォトサプライ), described above, was essential.

 

Omiya launched the Hansa Canon in February 1936. 1 Peter Dechert described the early days of the Hansa Canon commercialization:

 

"Although the Hansa Canon was originally advertised in October 1935, very few were available for purchase. Operating from their initial small workship in the Ripoongi area of Tokyo, Seiki Kogaku's assemblers and finishers were still learning the art of putting a precision camera together. Not until June 1936 was a larger facility in the Meguroku area acquired in order to 'produce large quantities' of the Canon camera." 1

As well as selling via Omiya, Seiki-Kōgaku also sold some of these Canons, without the Hansa logo, directly to photographers. Dechert states that the sales of the camera without the 'Hansa' logo was only about one-quarter the quantity of Hansa Canon sales 1.

 

The Importance of the Hansa Canon

 

The successful introduction of the Hansa Canon was the basis of a small and slowly growing company which was eventually to grow into the massive Canon Camera Company and eventually Canon, Inc.  Its success allowed Canon designers to develop and introduce the "Canon S" which initially was referred to as the "Canon Newest Model". This new camera was introducted in late 1938.  You may read about this interesting camera, which added slow shutter speeds and other features by clicking on this link to the Canon S camera.
