Revision as of 16:00, 15 August 2008
The Mycro (マイクロ) is a Japanese subminiature camera, released in 1939. It was made by Akita Seisakusho and distributed by various companies until 1945. After World War II, it was exclusively distributed by Sanwa Shōkai, and the maker's name perhaps became Mycro Camera Co. Ltd. at some time.
Contents
General description
The Mycro takes ten 14×14mm exposures on unperforated 17.5mm film, the same as its competitor the Midget, which was released two years earlier. The Midget and Mycro were certainly the first still cameras in the world to use this type of film, certainly obtained by slicing 35mm film in two.[1] After World War II the same format was adopted by Tougodo's Hit and a host of similar "Hit-type" cameras.
All the Mycro models have the same main body made of pressed metal. The lens and shutter assembly is mounted on a tube at the front. The lens is a fixed-focus 20mm f/4.5, and the aperture is set from 4.5 to 11 by an index placed under the barrel. The shutter has B, 25, 50, 100 settings selected by an index at the top, and the release lever is on the shutter casing itself. The film is advanced by a knob at the top left, as seen by the photographer. The back is hinged to the left and contains a single red window to control the advance.
Original model
Description and variations
The original Mycro has a tubular finder attached to the middle of the top plate, and a round film flange on the right. The red window on the back is uncovered and surrounded by a round metal frame. The back latch consists of a small sliding button. The shutter is everset and is tripped by a lever actuated by the photographer's right hand. The name Mycro is inscribed at the top of the shutter plate, above the lens. The ever-ready case is made of brown leather and embossed Mycro at the front; it curiously does not fully cover the top plate when shut.
Many variations are known on the original Mycro; these are detailed in this page at Mycro.jp and in this page at Submin.com. Two different markings exist on the right film flange, either a stylized A and a cross, or the words MYCRO T.A.Co. The letter "A" certainly stands for the manufacturer Akita, and "T.A." might correspond to the initials of the founder. Different lens markings are found, either 1:4.5 F=20mm at the bottom of the shutter plate and nothing on the lens rim, or F=20mm on the shutter plate and MYCRO ANASTIGMAT 1:4.5 on the lens rim. The latter might be a late variation, adopted before the release of the New Mycro. The back latch is either attached to the main body or to the back itself. Finally, some examples have a black painted finder instead of the regular chrome plated part, perhaps because of a shortage of raw materials during wartime.
History and documents
The Mycro was first announced in the new products column of the June 1939 issue of Asahi Camera.[2] In this document, the camera is attributed to the distributor Sasaki Shōten, the price is given as ¥18.50 and a dedicated hood with filter is mentioned for ¥1.80. The description states that the lens has four elements, maybe using the Rapid Rectilinear formula. It also mentions a "security device" on the shutter, actually a release lock; this is the S setting visible on the speed scale on some cameras. These two features are also repeatedly mentioned in advertisements.
The first advertisement for the camera appears in the October 1939 issue of Asahi Camera.[3] It takes two full pages and basically contains the same information, but does not state a price. The camera is pictured with and without its dedicated hood, and one of the pictures is unintentionally reversed. The company names are Mycro-sha on one side, and the distributors Sasaki Shōten and Yamamoto Shashinki-ten on the other. Mycro-sha might be the original name of the manufacturer; this name only appears in this particular advertisement.[4]
The November 1939 advertisement in Asahi Camera, placed by Yamamoto and Sasaki alone, consists of a single page. It gives the price of ¥18.50, case included, and mentions the hood and filter for ¥1.80.[5] A similar advertisement dated December clearly shows the A logo on the right film flange.[6] In addition to the advertisements placed by Yamamoto and Sasaki, the Mycro was also independently advertised by Matsuzaki Shashinki-ten from about that time.[7]
The November 1940 advertisement in Asahi Camera, placed by Tōyō Shōkai and Yamamoto Shashinki-ten, does not mention Sasaki any more.[8] The Mycro is presented together with the Light 4×6.5cm camera, at an unchanged price. The Mycro appears in the official list of set prices compiled in October 1940 and published in January 1941, for ¥19.[9]
Advertisements mentioning the manufacturer Akita Seisakusho and the distributor Sanwa Shōkai first appeared in Summer 1941.[10] The August advertisement in Asahi Camera shows the manufacturer's name together with that three distributors: Sanwa Shōkai, Mizuno Shashinki-ten and Yamamoto Shashinki-ten; that in the November issue shows Akita's name alone.[11] On both months, the price is given as ¥19, and the catch phrase is "An ultra-small camera unique in the world" (世界唯一の超小型).
Akita's name disappeared from the advertisements in 1942, and Sanwa emerged as the main distributor.[12] The April 1943 government inquiry on Japanese camera production lists the Mycro as made by Akita and distributed by Sanwa.[13] It also says that the lens has three elements and was made by Kigawa; this might mean that the actual lens scheme changed at some time.[14]
The original Mycro was advertised by Sanwa till late 1944 or early 1945.[15] In February 1944, the price was ¥25.64, it was ¥30.70 in September, reflecting the high inflation of the time.[16] The catch phrase used at the time was "Very small and delicate, as a jewel" (最小にして精緻、珠玉の如き); it would be used again after the war for a few years.
New Mycro
Description
The New Mycro (新型マイクロ) has a new top housing containing the viewfinder and extending to the right; this new styling was surely inspired by the New Midget (released in 1939). The shutter is now set by a small lever actuated by the photographer's left hand, and the rest of the body is unchanged.
The name MYCRO and the word PATENTS are engraved above the viewfinder. The shutter plate reads MYCRO at the top and F=20mm at the bottom, and the lens rim is sometimes engraved MYCRO ANASTIGMAT 1:4.5.
Evolution
The New Mycro was released in late 1944. The wartime model has a plain decorative knob above the top housing on the right, and always has the engraving on the lens rim. It appears in advertisements by Sanwa Shōkai in the September and November issues of Shashin Kagaku, where the price is given as ¥48.20.[17] This model seems particularly rare, but at least one surviving example is known, pictured in this page at Mycro.jp.[18]
The postwar model has a lesser finish. It lacks the decorative knob on the right, weld is used for the top housing and viewfinder eyepiece, and the engraving on the lens rim is absent on most cameras. There are disparities in the metal plating: nickel plating is applied on the top and bottom surfaces, or on the viewfinder housing alone, whereas the lens barrel is normally chrome plated. Other minor variations are known: the advance knob has different milling patterns and sometimes has an arrow engraved at the top,[19] the red window frame is either chrome or black, the camera's inside is either painted black or left in metal finish, etc.
The postwar model was sold very soon after the end of the war; an advertisement already appears in the February 1946 issue of Ars Camera.[20] The advertisement in Kohga Gekkan July 1947 seems to show the New Mycro again, shortly before the switch to the next model.[21] (In the documents, the name "Mycro New" (マイクロ新型) is sometimes used instead of "New Mycro".)
Transitional model
The New Mycro was followed by a transitional model, easily recognized by the SANWA SHOKAI marking under the lens. This model has a new spring-loaded back latch, replacing the sliding button inherited from the original model. It also has no frame around the viewfinder's front window.
The advertisement in Kohga Gekkan October 1947 shows a picture of the transitional model, which is still called "Mycro New" (マイクロ新型) in the document. The pictured camera has a milled lens rim with some engravings, and is marked Mycro PATENTS MADE IN JAPAN at the top. On the actual examples observed so far, the lens rim has no marking and is either milled or plain, and the MADE IN JAPAN mention is not always present on the top engraving.[22]
