Haha, what you want to ask about is the SLR camera?

Canon launched the Canon Flex, the first 35mm single-lens reflex camera in 1959.

In addition, post a little more about Canon’s history, so you can learn more about it!

Canon was founded in November 1933 as the "Precision Optical Research Institute". In 1934, a group of young people imitated the German Leica camera in Tokyo and developed Japan's first 35 mm focal plane shutter camera, the Kwanon model. In 1935, a 35mm focal plane camera, the Hansa Canon model, was launched. In the same year, Canon's trademark "Canon" was officially registered. "Precision Optics Industrial Co., Ltd." was formally established on August 10, 1937, and renamed "Canon Camera Co., Ltd." on August 15, 1947. Canon is the evolution of the Japanese word "Kwanon". For more than half a century, with the advent of Canon's new generation of cameras, Canon has created numerous firsts in the history of camera development in the world, and the "Canon" camera brand has become one of the most famous camera brands in the world.

Canon launched the Canon Flex, the first 35mm single-lens reflex camera in 1959. After years of research and development, the professional-grade 135 SLR model F-1 was launched for the first time in 1971, as well as the matching FD lens. This high-end professional camera, known for its durability, can be used in environments of -30°C and 60°C. The shutter of this camera has withstood the test of 100,000 times without failure and is made of advanced ultra-thin titanium. Horizontal curtain shutter. This well-designed professional camera caused a sensation in the entire photography world when it was launched.

In March 1976, Canon launched the fully electronic Canon AE-1, which for the first time adopted the "speed first, aperture automatic" automatic exposure mode. The AE-1 is the world's first all-electronic camera with a built-in computer central processing unit (CPU), ranking first on the market.

In 1981, Canon launched the improved Canon New F-1. This professional camera with outstanding performance became the weapon of many professional photographers for a long time in the 1980s.

In 1986, Canon launched the T90, the highest-end model in the T series. In addition to autofocus, other camera functions have reached a very high level. For example, it pioneered the shutter rear-curtain synchronized flash. The T90 was one of the most technologically advanced manual focus 35mm SLR cameras at the time.

In the mid-1980s, 35mm SLR cameras entered the era of autofocus (AF). In 1987, Canon launched the EOS (abbreviation for Electro Optical System) series of new mounts, which means "electronic optical system". Unlike other AF cameras, Canon installs the autofocus drive motor inside the lens, which increases the speed of autofocus. It will be followed by other camera manufacturers in the future. In 1989, the EOS Model 1, the top professional camera in the EOS series, was launched. In the two years from 1987 to 1989, Canon launched six AF SLRs in succession. The launch of the EOS 1 established Canon's dominant position in professional AF SLRs. In 1994, the second top professional camera EOS 1N was launched, just entering the 21st century. In 2000, the third professional camera EOS 1V was launched, becoming the flagship of Canon AF cameras.

During the development process of 35mm AF SLR cameras, Canon has created many world firsts, and the launch of each new model always surprises people. In 1992, the EOS 5 model was launched, which used the new eye-controlled focusing technology for the first time. It caused a great sensation as soon as it was launched.

In 1998, Canon launched its third eye-controlled focus camera, the EOS 3, which used 45-point eye-controlled focus. The 45 focus points were densely distributed in an ellipse with an area of ??8mmX15mm, occupying approximately 23% of the viewfinder area. The camera focuses wherever your eyes see, and the focusing speed is nearly four times faster than the EOS 5 model. The launch of this high-end camera marks a new stage in the development of Canon's eye-controlled autofocus technology.

It is worth mentioning that when Canon launched the EOS 1N, it also launched a sister camera, the EOS 1N RS camera. The camera uses an ultra-thin polyester sheet with a thickness of only 0.023 mm to make a fixed translucent reflector, which is then coated with a special 0.5 micron evaporated film. The photographer can still see the subject through the viewfinder during the exposure. , which is very beneficial for capturing dynamic, long exposures. Since the 1990s, digital photography has been developing at a rapid pace. Due to the advantages of digital photography, there is a tendency to catch up from behind. In 1995, the number of digital cameras in the world was only 410,000 pixels, but by 1996 it had almost doubled to 810,000 pixels, in 1997 it was increased to 1 million, and in 1998 it was 2 million.

Canon complies with the changing trends of the times. In order to meet the needs of professional photographers as quickly as possible, Canon takes the lead in developing single-lens reflex digital cameras that can use autofocus lenses. In 1995, Canon cooperated with Kodak to develop EOS Based on the 1N model as the prototype, three SLR digital cameras, EOS DCS1, EOS DCS3, and EOS DCS5, were launched. In 1998, EOS D2000 and EOS D6000 models were launched. The D2000 model was also based on the EOS 1N model. It was the SLR professional digital camera with the highest 2 million pixels at the time. It was the world's first equipped with a 1.8-inch color LCD monitor. It shined at the Nagano Winter Olympics in Japan that year and attracted many professionals. Photographers, starting with this digital camera, have left traditional cameras in the cold.

As we all know, the core component of a digital camera is a charge-coupled device, or CCD sensor for short. Due to the high production cost, the price of digital cameras has remained high, which has affected the popularity of digital cameras. Since entering the 21st century, Canon has independently developed a CMOS sensor in the development of digital cameras. In 2000, it launched the EOS D30, a SLR digital camera with 3.25 million pixels and using CMOS based on the EOS 30, which opened the door to the development of digital cameras. A new page in history.

In terms of the types of digital cameras, in addition to SLR digital cameras and the development of small digital cameras, Canon has also launched a series of digital cameras for various users to suit the different needs of photography enthusiasts. A series, IXUS series, S series, Pro series, G series, etc.

The A series has around 1-2 million pixels and is mainly designed for home users. A40 and A200 are representative models of this series. They are popular among home users for their simple operation and high cost performance. The IXUS series is a symbol of fashion. From the earliest IXUS V to the latest IXUS V3, they all draw on the compact and exquisite appearance design of the Canon IXUS series ASP cameras, coupled with the excellent imaging quality, they have been unanimously recognized by young and fashionable people.

The S series pixels are between the household A series and the high-end G series. They are very powerful and equivalent to the G series cameras at the time. They are only slightly inferior in some parameters. The pixel count is 200. -Around 4 million, the current representative model is the 4.1 million pixel S45.

In 1998, the Pro series launched its first camera, the Pro 70, which was loved by many photography enthusiasts for its excellent imaging. The Pro 90 IS, launched in early 2001, is a 10x zoom digital camera with an optical stabilization system, equivalent to a 135 camera lens 37-370mm, and is the darling of telephoto photography enthusiasts.

The G series is a high-end model. The early G1 had 3.34 million pixels and adopted a ground-breaking rotating LCD design, which not only facilitated viewing from multiple angles, but also effectively protected the display from being scratched. . Then G2 and G3 were launched, with 4.1 million pixels. Among them, G3 uses Canon's latest DIGIC chip, which improves image quality, focus accuracy and focus speed. It also improves the processing of details in dark and bright parts of the image.

Canon’s goal is to be a comprehensive provider of products and services in the digital imaging field. Compared with other digital camera manufacturers, Canon has advanced awareness and many years of experience in producing digital cameras when it comes to the development of digital cameras. Canon's products should be said to be very comprehensive in the fields in which they are good at. They are targeted at both the professional photographer market and the consumer market. They should be said to be very balanced and perform as well as in traditional fields.

In early 2002, in order to clarify Canon's market strategy in imaging products and services, Canon put forward the slogan "The Way to Perfect Images". This slogan runs through all specific work such as advertising, public relations, activities, promotions, and channel construction. In the new year, Canon will further expand the digital camera market and has set a higher goal in terms of expanding production and sales activities in China.

At the beginning of 2002, Canon launched the EOS D60 digital SLR camera with 6.5 million pixels, and at the end of the year, it launched the EOS 1Ds with 11.1 million pixels. This digital camera uses the top professional EOS 1V as a prototype and learn from the experience of the EOS 1D launched in 2001. The biggest highlight of this machine is that it is equipped with a CMOS sensor that is the same size as 35mm film. In other words, when using a lens, there is no need to multiply the lens focal length by a factor. Digital cameras also have a wide angle of view with an ultra-wide-angle lens, which makes people sit up and take notice. It can be said that the traditional 135mm camera has ushered in a real opponent.

1945--After the Second World War, it was able to independently manufacture lenses.

1946--Canon produced the first lens, the Serenar 50mm f/3.5I.

1951--The Serenar 50mm f/1.8I became famous all over the world because it improved the shortcomings of Gauss lenses, that is, poor performance at large apertures, and produced high-resolution images.

1961--50mm f/0.95 created another victory for Canon because it was the fastest lens in the world.

1968--FL 50mm f/1.4II was rated No. 1 by the authoritative Camera Mainichi Lens White Paper, allowing Canon to concretize the method of excellent color reproduction that later became the method for evaluating all Japanese SLRs At this time, the lens standard is developing the use of luorite as an alternative lens material. Fluorite has very special optical properties (the degree of refraction of red light to green light is very different from that of green light to blue light). Special local dispersion (extraordinary) partial dispersion), this characteristic can reduce the Secondary Spectrum improved by achromat, but the premise is that the impurity-free fluorite is large enough. When the uorite in nature is too small to be used as a lens, Canon developed impurity-free artificial fluorite. Crystal technology. (ps: Humans have known the special optical properties of fluorite as early as 1800).

1969--Announced FL-F 300mm f/5.6, the world's first photographic lens using fluorite. The invention and use of artificial fluorite made the greatest contribution to the lens:

( 1) Reduce dispersion. After the dispersion is improved by achromat, there is still a second spectrum, and achromat improvement has its theoretical limit focal length x 2/1000, which is especially obvious for ultra-telephoto lenses. The emergence of fluorite greatly improves this problem.

(2) Reduce the length of the ultra-telescope lens (using the low refraction of fluorite) (ps: Humans have used fluorite for microscopes before, because they do not need too much fluorite).

1971--The release of the FD lens series allowed Canon to receive more praise after the FL-F 300mm f/5.6. The characteristics of the FD series are high contrast, sharpness, color balance, easy operation, and mechanical quality. The FD 55mm f/1.2 AL is the world's first SLR lens to use aspherical surfaces. This is a great victory in lens production, because the light at the edge of the lens with traditional spherical lenses will not converge to the focus and produce a blurred point. Due to different refractive index, large apertures are prone to flare (a light spot caused by light reflection in the lens. This light spot can be large or small, covering the entire photo or part of it) or ghost (a kind of flare, different from the original photo). The image is oppositely symmetrical) (this is the reason why seniors warn novices to use the maximum aperture less). The shortcomings of this traditional spherical lens are all improved by aspherical lenses by reducing the steepness of the refraction of light at the edge of the lens.

1973--TS 35mm f/2.8 SSC allows photographers to move the optical axis parallel or tilt the lens to change perspective and depth of field respectively. This is a function that was originally only available in large cameras. SSC is Super-SpectraCoating , used to increase light transmittance and color reproduction FD 35-70mm f/2.8-3.5 SSC, short range zoom, large aperture, providing great convenience and simplicity for taking pictures. Photographers originally questioned that it was worse than a fixed focus, but were later convinced by it Excellent performance attracts people to use it.

1974--FD 300mm f/2.8 SSC, using fluorite, is of high quality and has quickly become the best choice for sports photography, especially its strengths in football photography.

1975--FD 400mm f/4.5 SSC, rear focusing system (Rear Focusing System), smoother focusing and lightweight mechanical structure. The other is a variable focus pitch system, which makes close-up focusing faster.

In the meantime, the FD series continued to develop.

1982--FD 14mm f/2.8L aspherical, the widest angle lens in this series, FD 35-70mm f/3.5-4.5, uses a molded lens barrel to reduce weight.

1985--FD 35-105mm f/3.5-4.5 affordable aspherical lens for amateurs, due to the development of mass production technology for aspherical lenses.

Canon’s design goal is to provide unique high-quality lenses that will remain at the forefront of the EF lens series for 10 years after production. Built on the excellent optical standards of the FD, coupled with the autofocus function, the FD lens series is for the F -1 Camera system such as the EF lens series is for Canon EOS SLR. The biggest difference between the two is the adapter. The EOS adapter has a large diameter and is mechanically fixed and electronically controlled. 1987--EF 50mm f/1.8, the first autofocus lens EF 300mm f/2.8L USM The first ultrasonic motor (Ultrasonic Motor) driven lens USM features high torque for optimal autofocus performance, quietness, fast focus, fast start/stop and high precision.

1989--EF 50mm f/1.0L USMEF 80-200mm f/2.8L EF 20-35mm f/2.8L.

1990--USM takes it to the next level. EF 35-135mm f/4-5.6 USM is the first mass-produced lens using "ring-type" USM. Obviously, the biggest challenge for EF after providing autofocus is to maintain or surpass the excellent optical properties of FD

1995--EF 75-300mm f/4-5.6 IS USM Image Stabilizer lens first times published.
