Minox


Minox 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 invented and produced in 1936, by Baltic German Walter Zapp. The Latvian factory VEF manufactured the camera from 1937 to 1943. After World War II, the camera was redesigned and production resumed in Germany in 1948. Walter 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 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 electrotechnical manufacturing business in Riga who then arranged a meeting where Zapp demonstrated the Minox prototype, 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, 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. 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. Newer electronic versions, such as the Minox TLX, remain in production, essentially unchanged in features from the LX model since the late 1970s. With the introduction of the LX came significant redesign of the camera's basic controls. There is also the fully electronic entry-level model, the EC, which has a very different internal design and has a fixed-focus lens. The production rate for these cameras is considerably slower than in former years, however, as Minox devotes more time to the design and marketing of OEM cameras under the Minox brand.
The MINOX TLX Camera was available until September 2014.
Interest in MINOX subminiature cameras is likely to increase as MINOX began manufacturing 8x11mm film in January 2015.

Spy camera

The Minox subminiature camera attracted the attention of intelligence agencies in America, Britain and Germany, and most of the Eastern Bloc 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 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, with 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 had a new 5 element lens 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 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 to new rare-earth element, high-index, low-dispersion, optical glasses becoming available. 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 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 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 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. For electromagnetic shutter cameras, the shutter dial starts with 1/15 sec, and ends with 1/1000, or starts with 1/30 and ends with 1/2000 ; the electromagnetic Minox camera also has an 'A' setting for automatic exposure, controlled by the built-in CdS or Spd 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 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.
8×11mm TLX Special Order models were available new until September 2014.

Matching the size of the slide film for the 8×11 MINOX cameras, MINOX also produced slide projectors ending with the auto-focus HP24 model.

Minox 35 mm cameras

Minox 35 mm compact cameras

In 1974 Minox introduced a very compact, 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 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.

Minox 35 mm compact camera versions

All the above models use a single 5.6 v PX27 battery which can be replaced with two CR 1/3N 3 V Lithium Batteries
by using an adapter.
All the above, except ML, and MDC use 2 x CR 1/3N 3V Lithium batteries or a single 6V SPX27 silver oxide battery. ML, and MDC use a single 6V PX28 battery.
Accessories for Minox 35 include: UV filter, ND filter, lens hood, eveready leather case, and dedicated electronic flash.

Other Minox 35 mm cameras

The few 35 mm cameras now offered are of the "point and shoot" style:

Minox 110 camera

MINOX 110S, a 110 film format camera was also once sold. The Minox 110S has a Carl Zeiss Tessar 25 mm/2.8 unit focusing lens, and magicube flash. It is the only camera with a rangefinder made by Minox. An external electronic flashgun was also available. Users report that the 110S provides particularly good results on modern 110 film.

Miniature retro cameras

Minox has expanded its range of 8×11 models by offering Minox-badged cameras styled as miniatures of famous classic film cameras of the past, manufactured by Sharan Megahouse of Japan, including:
All these retro cameras are equipped with 15mm F5.6 triplet lens, and 1/250 sec shutter. Using
