Olympus is a Japanese company making cameras and other optical products.
Before the cameras

The company was founded on October 12, 1919 under the name K.K. Takachiho Seisakusho (㈱高千穂製作所, meaning Takachiho Works Co., Ltd.) by Yamashita Takeshi (山下長). The address was Toyotama-gun Yoyohata-chō Hatagaya (豊多摩郡代々幡町幡ヶ谷) in Tokyo. The founder was previously employed by Tokiwa Shōkai, which provided the financial support for the new company. The chief engineer was Terada Shintarō (寺田新太郎), who previously worked for M & Katera Kōgaku Kikai Seisakusho, and the first products of Takachiho Seisakusho were microscopes and thermometers. At that time, Japan imported all its microscopes (and other instruments), mainly from Germany. The company had the clear ambition to rival, and even surpass, these high precision foreign imports. Olympus has been renowned to this day for its research on medical equipment.
The first microscope was released in early 1920, and was sold by Tokiwa Shōkai under its own Tokiwa brand. The trade name Olympus was applied for on the same year 1920 and granted in early 1921. The Olympus Tokyo logo was applied for in mid-1931 and registered a little later. The company supplied microscopes to the Japanese Navy and became a "Navy approved factory" (海軍指定工場, kaigun shitei kōjō) in late 1933. It offered an apparatus (the PM I) to take pictures with a microscope, consisting of a prism, a basic shutter and a dark-box taking a ground glass or 56×93mm glass plates, and a similar device, the PM II, with a bellows instead of a rigid dark-box.
First camera lenses
The company underwent research in camera lenses from about 1934, to diversify its activities. In October 1935, a dependent company, called Mizuho Kōgaku Kenkyūjo (瑞穂光学研究所, meaning Mizuho Optical Research Institute), was set up for this purpose. It was located in the same factory ground, and it was declared as a separate company only because of the rules for the allotment of electric energy. The research on camera lenses was transferred to a new plant in Shibuya, Tagoto-chō in 1936.
The company first tried to sell camera lenses alone. Prototypes of a 105/4.5, a 75/4.5 and perhaps a 75/3.5 were assembled in mid 1936. Their design was copied on the Tessar, with four elements in three groups, and their designer was Pr. Miyata (宮田尚一) under the supervision of Mr Suzuki (鈴木), chief of the optical department. The name "Zuikō" (瑞光) was adopted after a contest open to the company employees; it is a contraction of the first characters of "Mizuho Kōgaku".
The company wanted to sell the lenses alone but did not find any client, so it decided to make a camera around them, under its own "Olympus" brand. It is said that this was suggested to Takachiho officials by Miyazaki Shizuma (宮崎静馬), founder of Proud-sha, who offered to supply the camera bodies. This is how Takachiho launched its first camera, a 4.5×6 folder called Semi Olympus, said to be released in September 1936. The body was the same as the Semi Proud and the lens was the only part produced by Takachiho.
The company soon began to make its own Koho shutter and its own camera bodies. The bodies were made in the same Shibuya plant as the Zuiko lenses, and the shutters were made in the Hatagaya plant. The Olympus Standard and the Semi Olympus II were the first cameras entirely made by Takachiho, whose prototypes were pictured in advertisements dated 1937. The former, an ambitious project led by Sakurai Eiichi, was abandoned after ten prototypes were made; the latter, designed by Mr Kitakawa, was sold until 1940.
It seems that the founder Yamashita Takeshi wanted to emulate the German company Carl Zeiss, which made microscopes and camera lenses, among the best of the time, and had entered camera production with the creation of Zeiss Ikon. It is said that he already wanted to make cameras when he engaged Sakurai Eiichi in 1935. The Tessar was chosen as a model for the Zuiko lens, and the Semi Olympus II and Olympus Standard were positioned as rivals of the Ikonta and Contax. However the company chose to develop its own camera designs instead of copying the German models, unlike most other Japanese companies of the time. In Sakurai's own words, "to make cameras the same as the others was not interesting".
Wide aperture lenses
Back in autumn 1936, Takachiho received a subsidy of ¥9,000 to develop high aperture camera lenses from Japanese optical glass. This money was invested in the purchase of optical instruments, including an Askania optical bench installed in 1937. Three lens designs emerged from this research: the Zuiko 65/2.7 and Falcon 65/2 advertised in 1937 for the Olympus Standard, and the Olympar f/1.5, which would be produced as the Zuiko 50/1.5 and sold to Shimazu Seisakusho for X-ray cameras around 1940.
The Olympus Six was launched in 1940 in 6×6 format. It was the first of a line of 6×6 folders that would last until about 1957 with the Olympus Chrome Six series. Some of these cameras received a five-element lens called S Zuiko.
Takachiho fell under the control of Ataka Shōkai (安宅商会) in 1939, and Chatani Yasusaburō (茶谷保三郎) became the CEO of the company, whereas Yamashita Takeshi resigned on the following year. In 1942, the company name became Takachiho Kōgaku Kōgyō K.K. (高千穂光学工業㈱, meaning Takachiho Optical Industries Co., Ltd.). Because of the war, dispersal plants were opened in Suwa (諏訪, 1943) and Ina (伊那, 1944), both in Nagano-ken (Central Japan). The Shibuya plant was evacuated to Suwa, in a former textile factory. The Hatagaya plant was not evacuated, and it was destroyed by an aerial bombing on May 25, 1945, with all the archives and the microscope production line. The production line of the Koho shutter was also located in Hatagaya and was destroyed as well; this is why Olympus stopped the production of camera shutters for a number of years.
After the war

The production of the Olympus Six camera was resumed in early 1946 in the Suwa plant. It is said that officials from Mamiya visited the Suwa plant on the same year, to sign contracts about the supply of Zuiko lenses for the Mamiya Six bodies. In 1948 was launched the Olympus 35, a 35mm camera with a lens shutter, and the Olympus Chrome Six, an evolution of the Olympus Six with a diecast body. The company headquarters at the time were in the Shibuya plant, and the logo was the same OLYMPUS TOKYO as in the prewar period. On January 1st, 1949 the company adopted the name Olympus Kōgaku Kōgyō K.K. (オリンパス光学工業㈱, meaning Olympus Optical Industrial Co., Ltd.); the official English name was Olympus Optical Co., Ltd. An OLYMPUS OIC logo was used for some time after that date, where "OIC" stands for Optical Industrial Company. In the early 1950s, the headquarters moved back to Hatagaya, and the commercial department settled in Ginza.
In the 1950s there was a TLR vogue in Japan, and Olympus followed the trend from 1952 to 1956 with the 6×6 Olympus Flex. In 1959, after the Rolleiflex Baby Grey had initiated a short revival of the 4×4 format, the company announced the Eye 44 auto-exposure TLR, but it remained at prototype level. During the same year 1959 Olympus launched the Pen half-frame camera, designed by Maitani Yoshihisa, the first of a long series. Its compactness and sleek lines were revolutionary at the time, and it could take 72 shots without reloading on a standard 35mm cassette. This time it was Olympus that was setting the trend, and after the Pen many other camera companies began to produce their own half-frame cameras. Olympus was the only one to make a half-frame SLR system, the Pen F, released in 1963. The Pen cameras are still popular today among enthusiasts.
Microscopy was still as important to Olympus as photography. The PM5 microscope camera was made in 1951, the PM6 in 1955, and the PM7 in 1964. These all comprise a camera body with a tube coupling to the microscope, incorporating a shutter and a beam-splitter serving the side viewfinder. An exposure meter for the microscope cameras was available.
Trip, OM and XA

1972 saw the launch of the OM 35mm SLR system. At a time when the large and relatively heavy Nikon F was still the workhorse of professional photographers, the compact OM system was once again revolutionary. The system incorporated a large line of highly-regarded Zuiko lenses, interchangeable focusing screens, winders and, later, advanced flash units. While never quite challenging Nikon and Canon as the leading choice of professional photographers, Olympus did have a loyal and dedicated following for the OM system, including David Bailey and Lord Lichfield. The OM system has also kept a good reputation among astronomers, macro and micro photographers; this is related to the company's involvement in medical and research equipment.

Into the present
During the mid-to-late '80s Olympus lost ground to its competitors in the SLR field as autofocus took off. Research and development spending was focussed on high-selling compact point and shoots. Although the company did eventually release an autofocus SLR system it was not a serious challenge to Minolta, Nikon or Canon. Olympus changed its orientation and pioneered the concept of the "bridge" camera (an auto-everything SLR with fixed zoom lens) with the IS series. In the early '90s, Olympus had significant success with the compact autofocus Stylus (or µ[mju:] ) line. It carried on this success at the turn of the century into the digital field, as film camera production was ended in 2005. When the digital market took off with the launch of reasonably affordable, compact 2.3 megapixel cameras for consumers, there were only two real options for photographers — the Nikon Coolpix or the Olympus Camedia ranges. Before the availability of affordable (sub-$5k) digital SLRs, Olympus' E series of fixed-lens SLRs, evolved from the earlier analogue bridge cameras, was very popular among serious photographers.

The launch of cheaper digital SLRs saw Olympus lose ground again among serious photographers, but in 2003 the E series was developed into an innovative interchangeable-lens SLR system. Without the huge autofocus lens catalogue of Nikon and Canon, Olympus was free to build its system without concessions to an older 35mm-based system. Olympus is the champion of the Four-Thirds lens mount system with smaller sensor rather than the APS-sized sensors Konica Minolta, Canon and Nikon put into their DSLR bodies, which are derived from 35mm film cameras. This allowed Olympus to design its bodies and lenses specifically for digital use. The first model of its Four-Thirds E-series of DSLRs was the Olympus E-1. It was the first professional model of the modern type compact DSLRs for interchangeable lenses. Olympus is slow in evolving its professional DSLR line but fast in delivery of new consumer DSLRs of its E-line.
Along with Panasonic, Olympus has also launched a compact camera system based on the Micro Four-Thirds standard. This has half the flange focal distance of the orignal Four-Thirds, 6mm smaller throat size, and enables compact cameras with DSLR image quality. For this it revived its famous Olympus Pen brand. The new Pens are finderless compact digicams for Micro-Four-Thirds lenses, but including an accessory shoe where an electronic eye-level finder can be attached instead of a flash.
The company took its present name of Olympus Corporation (オリンパス株式会社) in 2003, and it continues to innovate and to challenge other manufacturers to do so by the incorporation of features such as 'Live-View', tilt/swivel LCDs and full user control over the noise filter on its 'E-System' range of DLSRs.
Revelations about the top management of Olympus made world headlines in late 2011, regarding accounting practices designed to disguise earlier losses. As of February 2012, investigation continues into what is commonly referred to as a scandal, and has led to resignations and arrests of Olympus officials. These events cast doubt over the future of the corporation's camera division (whose earnings had not matched those of the medical-products arm); yet new Olympus camera and lens introductions continue.

Olympus traditionally brands all its lenses with the name Zuiko, a system begun with the very first Olympus camera released, and carried on throughout the various camera formats and systems since then. The company sold some Zuiko 7.5cm lenses to other camera manufacturers. It also made two lenses for a third-party lens mount in the early 1950s: the Zuiko 4cm f/2.8 for Leica and the Zuiko 4cm f/3.5 for Exakta.
