# Minox

Minox (pronounced /ˈmiːnɒks/ MEE-noks) is a manufacturer of cameras, known especially for its subminiature camera.
The first product to carry the Minox name was a subminiature camera, conceived in 1922, and finally produced in 1936, by Baltic German Walter Zapp. The Latvian factory VEF (Valsts elektrotehniskā fabrika) manufactured the camera from 1937 to 1943. After World War II, the camera was redesigned and production resumed in Germany in 1948. Zapp originally envisioned the Minox to be a camera for everyone requiring only little photographic knowledge. Yet in part due to its high manufacturing costs, the Minox became more well known as a must-have luxury item. From the start the Minox also gained wide notoriety as a spy camera.
Minox branched out into 35 mm film format and 110 film format cameras in 1974 and 1976, respectively. Minox continues to operate today, producing or branding optical and photographic equipment.

## History

From 1936 to 1975, the history of the Minox brand is essentially that of the Minox subminiature camera. From 1975 the Minox name also became associated with other products, most notably the Minox 35 mm compact cameras produced from 1975 until 2004.
Minox was acquired by Leica in 1996, but a management buyout on 25 August 2001 left Minox an independent company again.

## Minox subminiature camera
### Subminiature camera history

The original Minox subminiature camera was invented by Walter Zapp in 1936. Zapp, a Baltic German, was born in 1905 in Riga, then part of the Russian Empire. The family moved to Reval (now called Tallinn, Estonia) where he first took a job as an engraver before finding a position with a photographer. He became friends with Nikolai 'Nixi' Nylander and Richard Jürgens, and it was through discussions with these friends that the idea of a camera that could always be carried came to him. Nixi Nylander also coined the name "Minox" and drew up the Minox mouse logo. Jürgens funded the original project but was not able to get support in Estonia for production. Jürgens contacted an English representative of the VEF (Valsts Elektrotehniskā Fabrika) electrotechnical manufacturing business in Riga (by then independent Latvia) who then arranged a meeting where Zapp demonstrated the Minox prototype (UrMinox), with a set of enlargements made from Ur-Minox negatives. Production began in Riga at VEF, running from 1937 until 1943. In the same time, VEF had received patent protection on Zapp's inventions in at least 18 countries worldwide.
Shortly after its introduction, the Minox was widely advertised in The European and American markets. It did not surmount the popularity of 35 mm cameras (which were then referred to as "Miniature Cameras"), but did achieve a niche market. It also attracted the attention of intelligence agencies in America, Britain and Germany, due to its small size and macro focusing ability.
Ironically during World War II production of the Minox was put in jeopardy several times as Latvia fell victim to invasion by the Soviet Union, then Germany, and then by the Soviets again. Cameras were produced under both Russian and German occupation nevertheless, and the camera became both a luxury gift item for Nazi leaders as well as a tool for their spies. In the meantime, Zapp and his associates protected their interest in the product by searching for alternative production facilities in Germany.
After World War II, production of the Minox II began in 1948 at a new company, Minox GmbH, in Giessen/Heuchelheim near Wetzlar, West Germany. The new camera very much resembled the original, but was made with a plastic chassis covered by an aluminum shell. This greatly reduced its weight and, to an extent, cost. The camera continued to appeal to a luxury "gadget" market which broadened during the 1950s and early 1960s. It also continued to see use as an espionage camera by both sides during the Cold War. During this time, the Minox company continued to develop the camera, working with Gossen to develop a companion miniature exposure meter, as well as improved models such as the Minox B, which incorporated an even smaller Gossen-designed meter into the camera itself. The Minox B became the most popular and widely produced model of the line. Further developments included autoexposure, and the company developed an extensive line of accessories. These included flash guns, viewfinder attachments, tripod mounts, and copying stands, all increasing the camera utility in a variety of applications. One accessory even allowed the camera to use a pair of binoculars as a telephoto lens (see illustration). Limited editions of the camera were also produced in a variety of luxury finishes, such as gold plating. Standard cameras were also available in an optional black anodized finish.
The Riga Minox camera, along with the luxury finish postwar cameras, are now collector's items. All-mechanical models A and B remain in use by hobbyists. In 1969 the model C became the first camera of its kind to incorporate electronic exposure control. With the introduction of the LX came significant redesign of the camera's basic controls. It was followed by the last production model, the TLX. There was also a fully electronic entry-level model, the EC, which had a very different internal design and a fixed-focus lens. The production rate for these cameras was considerably slower than in former years, however, as high production costs and increasing competition from Japan sharply reduced sales and revenues.
Beginning in 1981, MINOX experienced increasing difficulties. A quarter of the original 750 employees had to be made redundant. A settlement request was filed with the District Court in Giessen on November 21, 1988. Under the direction of the receivership administration, the workforce was reduced to just under 300, and the business was extensively reorganized.
The MINOX TLX Camera was available until September 2014. Minox is now part of the Blazer Group GmBH, with its facilities in Isny im Allgäu in the south of Germany, with a service facility remaining in Wetzlar. Production of 8x11 film ended in 2015.
The company now produces high-quality sports optics and night-vision devices, its only camera models being trail cameras.

#### Spy camera

The Minox subminiature camera attracted the attention of intelligence agencies in America, Britain and Germany, and most of the Eastern Bloc (East Germany, Romania) due to its small size and macro focusing ability. There is at least one document in the public record of 25 Minox cameras purchased by the US Office of Strategic Services intelligence organisation in 1942.
The close-focusing lens and small size of the camera made it perfect for covert uses such as surveillance or document copying. The Minox was used by both Axis and Allied intelligence agents during World War II. Later versions were used well into the 1980s. The Soviet spy John A. Walker Jr., whose actions against the US Navy cryptography programs represent some of the most compromising intelligence actions against the United States during the Cold War era, used a Minox C to photograph documents and ciphers.
An 18-inch (460 mm) measuring chain was provided with most Minox subminiature cameras, which enabled easy copying of letter-sized documents. The espionage use of the Minox has been portrayed in Hollywood movies and TV shows, and some 1980s Minox advertising has played up the "spy camera" story.

#### Other special uses

A Minox B, operated by remote trigger and protected in a special housing, was used to inspect the interior of the United States Army's SL-1 experimental nuclear reactor after it experienced an internal steam explosion in 1961. This camera and housing were shown in the film report released following the accident investigation.

### Technical details of Minox 8×11 cameras

The original Riga-made Minox had a brass chassis covered in a stainless steel shell, which telescopes to reveal or cover the lens and viewfinder windows, as well as to advance the film. It was equipped with a parallax correcting viewfinder, which was coupled to a Cooke triplet type Minostigmat 15 mm f/3.5 lens. The lens was capable of focusing as close as 20 cm, and, due to its small image size, provided such depth of field at full aperture that a diaphragm was deemed unnecessary. The maximum focus zone was about one meter to infinity. In front of the lens was a metal foil curtain shutter, which was itself protected by a window. These were advanced features at the time for any camera, regardless of size.
The dimensions of the Minox subminiature camera are: 80 mm × 27 mm x 16 mm; weight: 130 g.
The Minox cameras project an image of 8×11 mm onto the negative. The film is in strips 9.2 mm wide, or less than one-quarter the size of 35 mm film, and unlike 35 mm film, it has no sprocket holes. This film strip is rolled up in the supply side chamber of a small twin chamber cartridge, with the film leader taped to a take-up spool in the take up chamber. The film strips can be up to 50 frames in length for Riga Minox and Minox II, III, IIIs and B cameras. From Minox BL and C cameras onward the Minox film cartridge holds 15, 30, or 36 exposures.
The VEF Riga has a three-element flat film plane lens. Performance could be improved, so the short-lived Minox II (1948–1951) had a new 5 element lens (called complan) whose final element would rest against the film itself when the pressure plate pushed the film onto the lens. Customers complained of film scratches with this new design, so most of these lenses were replaced by MINOX with the later curved-field compensating lens. Consequently, original 'film lens' Minox II are exceptional. Early Minox cameras from Minox A/III to Minox B were equipped with a four-element, three-group Complan (lens) designed by ex-Leica lens designer Arthur Seibert. The Complan lens has a curved film plane, hence in these cameras the negative must be held in an arc to improve the edge-to-edge sharpness of the image. The Minox enlarger also holds the negative in this same curve. Later models, beginning with late model Minox B, to the current model TLX, using the 15 mm f/3.5 four-element, three-group flat-field Minox lens, holds the negative flat. The advance was attributed by Rolf Kasemeier (Small MINOX Big Pictures 1971 edition) to new rare-earth element, high-index, low-dispersion, optical glasses becoming available (probably from Schott Glass, of Jena). Note that lens performance between old and new complan/minox lenses was rated by MINOX themselves as identical.
At this time to differentiate between negatives taken with the older complan lens and negatives taken with the later minox lens, MINOX introduced an edge code in the negative. Since the MINOX C (the first camera released with the new minox lens) every 8x11mm camera had a distinct edge code to identify the camera. The reason was that commercial processors used MINOX enlargers. As the minox lens replaced the complan, so the enlargers had to change lenses: MINOX II enlargers were curved negative track and complan lenses, MINOX III enlargers were straight negative track and minox lenses. Ironically, owners of Rigas and model II cameras would get better results from a MINOX III enlarger than a MINOX II enlarger.
The early Minox cameras from Riga to Minox B, BL and AX, were equipped with a mechanical shutter, while later model Minox ( C, LX, EC, TLX ) cameras have an electromagnetic shutter. When closed, the viewfinder and lens windows are protected. Complan lens and Minox lens are unit focusing lens, focusing from 8 inches (20 cm) to infinity through precision gear linked to a focusing dial on top of the camera. All Minox cameras, except the EC and MX, have a parallax correction viewfinder: when the focusing dial moves, the viewfinder moves in tandem to correct for parallax.
From the Riga to Minox B, the film counter counts up to 50, while from Minox BL, C, to TLX, the film counter counts down from 36/30/15. For mechanical Minox 8x11 cameras, a separate shutter speed dial sets the shutter speed from 1/2 to 1/1000 second, plus B and T (the BL model has no documented T). For electromagnetic shutter cameras, the shutter dial starts with 1/15 sec, and ends with 1/1000 (Minox C), or starts with 1/30 and ends with 1/2000 (Minox LX/TLX/CLX); the electromagnetic Minox camera also has an 'A' setting for automatic exposure, controlled by the built-in CdS (Minox C) or Spd (Minox LX/TLX) exposure meter.
Above the viewfinder is a filter bar used to slide a yellow, green or an orange filter in front of the lens; starting with the BL, there is only a Neutral Density filter.
For Riga Minox to Minox B, the film advances each time the camera is closed, regardless of whether a picture is taken or not. Opening the camera causes the pressure plate to press the film into a concave or flat (depending on the model) surface to stiffen thin emulsions for better clarity. When the camera is closed, the pressure plate moves back from the film plane, thus allowing the film strip to move freely to advance to the next frame. From Minox BL onward, the camera is equipped with a "freewheeling" mechanism, such that the film advances one frame only when a picture is taken, otherwise, closing the camera does not advance a frame.
Minox BL uses a PX625 button cell to power the CdS exposure meter; Minox C, LX, EC, used a 5.6v PX27 mercury battery to power the exposure meter and electromagnetic shutter. TLX, CLX, ECX use four 1.5v 386 silver oxide button cell in an adapter; this adapter combo can also be used to replace the discontinued 5.6v PX27 battery for Minox C, LX and EC.

## Minox 35 mm cameras
### Minox 35 mm compact cameras

In 1974, Minox introduced a very compact (100 mm × 61 mm × 31 mm), glass fibre reinforced Makrolon bodied 35 mm film camera designed by Professor Fischer of Vienna University: the Minox EL, the first one in Minox 35 mm series. These compact cameras featured a drawbridge style lens cover which when lowered brought forward a 35 mm focal length f/2.8 four-element, three-group Tessar-type Minotar/Minoxar lens with between the lens leaf shutter and diaphragm, a center positioned viewfinder, two stroke film winder lever and a film rewind knob. The Minox 35 camera back must be removed for loading or unloading film.
The camera offered aperture priority exposure with the option of manual settings. The Minox 35ML and Minox M.D.C offer program mode (P mode) exposure in addition to aperture priority. The 35 mm/2.8 Minotar/Minoxar lens was very sharp, with low distortion, while the camera's metering-system's capability to produce excellent results especially under low-light conditions was outstanding – using exposure times of up to two minutes.
Some models have a 2x backlit exposure switch and a 10 sec timer switch. When the timer is engaged, a flashing LED indicates the timer counter is counting down, for the last two sec, the flash interval shortened.
Until 1995, the Minox 35 cameras were considered the smallest cameras for the standard 35 mm film format. The design was inspired by the Rollei 35, which had been the smallest 35 mm camera for eight years. The Rollei 35 is only slightly bigger, but much heavier than the Minox 35 cameras. However, the Minolta TC-1, introduced in 1996, is smaller.
