Canon is an old camera manufacturer in Japan. At the beginning of the 20th century, Japan's camera industry was very backward. At that time, most people used foreign products. To this end, in order to make domestic (of course, Japan's own production) cameras, several Japanese young people began to imitate German high-end cameras, and successfully copied German Leica cameras in a small factory in Tokyo in 1934, and also developed Japan's first 35mm focal plane shutter camera KWANON (the Roman word for "Guanyin" in Japanese). The symbol of early Canon was "Avalokitesvara with a Thousand Hands". It was not until 1935 that KWANON was changed to CANON, which took the meaning of English standards and norms (KW is difficult to pronounce, so it was changed to a pronunciation similar to C/K/. Canon's CA has the pronunciation of "checkpoint card" in Japanese, and its origin is Kwan of Guanyin! ! ); The name was changed and the logo was changed three times. It was not until 1955 that Canon's logo was finally determined, which is the logo we saw today.

Canon-Canon's name comes from beauty. The founder of Canon is a doctor of medicine, whose name was inspired by looking up at the sky. Canon, formerly known as SEIKI KOGAKU KENKYUJO, is a precision optical instrument research institute. Canon originally had a very English name KWANON, which means the name of a kind Buddhist goddess. In this name, the company ordered its first 35mm ranging camera. So far, there is only one KWANON camera in the world. About 1936, the company officially launched the camera of Lufthansa Canon brand. Since then, Canon has become a world-famous camera brand and a symbol of the company. Undoubtedly, there are more and more resounding names. EOS (Electron Optical System) used now not only stands for the abbreviation of the English initials of electron optical system, but also stands for a Greek goddess named Dawn.

198 1 year, Canon introduced an improved new Canon product, F- 1, which is a professional camera with outstanding performance and has become a weapon for many professional photographers for a long time in the 1980s.

1986 Canon introduced T90, which is the highest grade in the T series. In addition to autofocus, other functions of the camera have reached a high level. For example, the shutter Hou Lian synchronous flash is the first. T90 was one of the most advanced manual focusing 35mm SLR cameras at that time.

In the mid-1980s, 35mm SLR entered the era of automatic focusing (AF). 1987, Canon introduced EOS (abbreviation of electro-optical system) series with brand-new bayonet, which means "electro-optical system". Different from other autofocus cameras, Canon installed an autofocus drive motor in the lens to improve the autofocus speed. It will be imitated by other camera factories in the future. 1989, EOS 1, the top professional camera in EOS series, went on sale. During the two years from 1987 to 1989, Canon has successively launched six AF SLR machines, and the launch of EOS 1 has established Canon's leading position in the professional AF SLR machines. 1994 introduced the second professional top matching machine EOS 1N, which has just entered the 2 1 century. In 2000, the third professional machine EOS 1V was launched, which became the flagship of Canon AF camera.

Canon has created many firsts in the world during the research and development of 35mm AF SLR, and the launch of each new model will always surprise people. EOS 5 was launched on 1992, which used the new technology of eye control focusing for the first time, and caused a great sensation as soon as it went on the market. 1998, Canon introduced the third eye-controlled focusing camera EOS 3. This camera uses 45-point eye control focusing, and 45 focus points are densely distributed on an ellipse with an area of 8mmX 15mm, accounting for about 23% of the viewfinder area. The camera focuses where the eyes see it, and the focusing speed is nearly four times faster than EOS 5. The launch of this high-end camera marks the development of Canon's eye-controlled autofocus technology to a new stage.

It is worth mentioning that Canon launched a sister EOS 1N RS camera at the same time. The machine uses ultra-thin film polyester sheet with a thickness of only 0.023 mm to make a fixed semi-transparent mirror, which is coated with a special evaporation film of 0.5 micron. Photographers can still see the subject from the viewfinder during exposure, which is very beneficial for capturing dynamic and long-term exposure. Since 1990s, digital photography has developed rapidly. Because of the advantages of digital photography, it has a tendency to catch up. 1995, the number of pixels of digital cameras in the world was only 4 10000, but in 1996, it almost increased by 8 10000 times, and in 1997, it increased to 10000.
