Japan s SLR learned from Germany, but it can lead the world, why can t my country make it?

China, as a big country, can send rockets into space, but it can't even build a small digital camera, why is that? Is it because the camera manufacturing process is very difficult, or is our technology not in place? Let's talk about it. <>

Japan has a monopoly position in the SLR, because Japan has a lot of experience in the research and development of optical and electronic products, and Japan's technology is also learned from Germany, and now it is far from being able to lead the world. Because Japan has made great breakthroughs in machinery manufacturing and optical industry, it has also had a lot of innovation, so it has led to the rapid development of Japan's electronic technology, and at the same time, Japan is also vigorously promoting innovation, and finally manufactured a lot of relatively high cameras, so Japan's SLR can achieve a leading position in the world. <>

Although the camera is very small, it is a very precise instrument, from the inside to the outside reflects the design of the process, and at the same time, there can be no mistake in every precision instrument, because the camera wants to shoot better pixels, it must make the process design strong. Because the camera is a very precise processing process, a piece of optical glass can be processed for several months in order to become a good lens, but in this processing process, it is a huge test for precision machine tools, and China is at a disadvantage in this regard. There is not enough experience and technology in other optical components, so it is difficult to build a DSLR camera.

China can also make SLR cameras, but the quality of the image sensor and sensor will be poor. It is unlikely to surpass Japan at present, because Japan has been ahead of other countries in the field of digital cameras, and it is basically in a monopoly market situation, even if China now has the ability to study some image sensors, but it also takes a lot of money and time, and it also has to compete with Japanese manufacturers, but today's competition is very difficult, and the cost is also very high, if Chinese manufacturers want to make SLR cameras for sale, then it is also an unprofitable situation, That's why Chinese manufacturers don't produce SLR cameras.

Because China does not have a very in-depth research on SLR technology, if China wants to manufacture the world's leading SLR, it will definitely be able to make it.

China's technology in this area is not developed enough, and some resources are relatively lacking, so it cannot be built.

This is because the manufacture of SLRs requires technical accumulation, optical accumulation, and so on, and these are not a matter of a moment.

Through nearly half a century of accumulation, the Japanese manufacturer has reduced R&D and manufacturing costs.

It's very low, it's the Chinese companies that even the state has the power to make the camera, and he has a lot of patents, and if you don't use their plans, so you can only develop them yourself, patents, and the cost increases, and if you don't use them to develop your own solutions, the cost may be higher. Even if you cut the cost to the extreme, and finally make a 20,000 yuan, it's very, very great, a top-of-the-line camera in every way. The SLR is basically Japanese, the Korean product has just come out, almost no one buys it, the American product does not exist, the German product is very good, but it is surprisingly high, almost the same as a car.

At present, there are no SLR companies in China. Production technology for electronic sensors.

Almost completely controlled by Japanese manufacturers, no other country can do this.

Although Germany is the best in lens processing technology, the Japanese have done the best industrialization, that is, it is cheaper than the best, and it is very cheap than it. Financial pressure, talent pressure, and most importantly consumers do not recognize new brands (we usually buy products from professional companies, especially well-known brands), not because they do not produce, but because they do not have the production capacity, DSLR cameras.

CCD and CMOS cannot be produced in China. There are relatively few people who use DSLRs. Canon and Nikon have mature technology in DSLR cameras, producing dozens of DSLR cameras.

In addition, Sony and Pentax have also joined the ranks of the production of DSLR digital cameras, and the market competition is already quite fierce.

None of the Chinese companies have the technological capabilities to compete with Canon, Nikon, Sony and Pentax. Sony's DSLR digital cameras are sold for just 2,000 yuan in the Chinese market. Even if a Chinese company can produce a DSLR camera, it may not be able to sell it.

Digital SLR is a precision instrument integrating light, machinery and electricity, and its difficulty is far beyond the imagination of ordinary people. The obvious fact is that the countries that can build digital SLR cameras are better than artificial satellites.

Less! It has a high demand for electronics, machinery, materials, optics, processing and other technologies, and has developed rapidly. There are many technologies that have so far only been mastered by Japan.

A DSLR is similar to an engine, it is a thing that repeats precision! This is China's weak point, just as we can make disposable rockets, missiles and spaceships.

But I never understood how to make an engine.

The difficulty of manufacturing a single-lens reflex camera is by no means very difficult to imagine, it is a precision equipment that integrates electric shielding or, light, and machinery, and the countries that can build the SLR phase and finger machine are less than the countries that can build rockets.

The research and development of SLR cameras is very difficult, and the data value needs to be mobilized.

There's a lot of stuff involved, including optics, mechanics, and electronics. It's hard to put these things together.

China's technology in this area is not particularly good, and it also lacks certain materials and resources, so it cannot be built. The process of DSLR research is particularly difficult.

Because China does not have a very deep study of SLR technology, there are some difficulties in the research of SLR cameras, but I believe that if our country does it, it will definitely be better than Japan.

Japan's SLR technology is better than Germany's is caused by the difference in the importance of the optical industry of the two countries to the civilian photography market, Germany was a well-deserved photography giant before the war, in addition to being divided by the United States and the Soviet Union after the war (Zeiss was robbed by the United States and the Soviet Union in turn), plus many technical experts were hijacked, lost, and the transformation of the economic structure, so it did not pay much attention to the development of civilian photography technology, and Japan is known to have been in the 60s of the last century in the 60s of the last century, Japanese Kannon (the predecessor of Canon), Tokyo Optics (the predecessor of Nikon), Konishi Roku (the predecessor of Konica) and so on all started to copy German cameras for a living, and gradually embarked on the road of independent design and innovation. At that time, the mainstream photographic equipment in Europe and the United States (including Germany) was the rangefinder camera (SLR had just begun to be popularized), and Japan began to innovate a large number of SLR technology and pulled down the ** through industrial production, so as to quickly gain the market (the operation of SLR cameras is simpler than the rangefinder, which is also an important basis for the popularization of SLR), and then Japan used its advantages in the field of electronics to continuously strengthen the electronic performance and automation functions of products, so in the 80s, Japan's SLR fully occupied the global market and entered a virtuous circleSo the bigger the market, the more profitable, and the better the technology.

On the other hand, in the German optical industry, Leica focuses on niche rangefinder production, Zeiss has stopped producing civilian photographic equipment independently for many years (there are many licenses and OEM), but focuses on glasses, medical equipment, astronomical equipment and other fields. Germany's civilian photography, including SLR technology, has been widened by Japan.

It's also interesting to watch a group of people copy the material, and Germany is not so easy to boast. Now when it comes to SLR, it is all DSLR, Germany except for LEICA, who still makes DSLR, no one has done it at all, and in the same case, N and C are much better than LEICA. It can be said that in addition to feelings, there is really no reason to choose, of course, in terms of optics, lenses, Germany still does not say, finished digital SLR, that is a joke.

Because most of the innovation is done by Japanese manufacturers.

In 1935, the Soviet Union built the world's first 135 single-lens reflex camera (which means "sport" in English).

In 1936, Germany built the first mass-produced 135 single-lens reflex camera, the Jhagee Exakta.

In 1949, Germany built the first pentaprism single-lens reflex camera, the Contax S.

In 1950, Germany built the first single-lens reflex camera with interchangeable viewing windows, the Exakta VX.

In 1954, Pentax Corporation of Japan released the world's first reflector instant automatic rebound single-lens reflex camera, ASAHIFLEX II

In 1958, Germany built the first Contaflex reflex camera with built-in light metering mirrors.

In 1960, Japan produced the first high-speed longitudinal metal shutter monoscope reflex camera Konica F with a maximum speed of 1 2000.

In 1960, Japan manufactured the first high-speed transverse focal plane shutter single-lens reflex camera Canon R2000 (Canon R2000), with a maximum speed of 1 2000).

In 1960, Japan manufactured the first behind-the-mirror (TTL) single-lens reflex camera, Pentax Spotmatic, which was commercialized in 1964.

In 1966, Minolta Corporation of Japan released the world's first full-aperture TTL split metering single-lens reflex camera SRT-101.

In 1971, Pentax Corporation of Japan released the world's first full-aperture pre-automatic single-lens reflex camera ES.

In 1971, Japan's Canon released the world's first full-aperture shutter automatic** single-lens reflex camera FTB.

In 1972, Canon released the F-1 Motor, which was the fastest movable mirror single-lens reflex camera at the time with a continuous shooting speed of 9 frames per second.

In 1977, Minolta launched the XD (or XD-7 XD-11), which was the world's first single-lens reflex camera with multiple auto** modes.

In 1981, Pentax Corporation of Japan announced the world's first autofocus single-lens reflex camera, the ME F[1].

In 1985, Minolta Corporation of Japan released the world's first LCD screen and autofocus all-electronic single-lens reflex camera 7000 (maxxum 7000 in the Americas[2]).

In 1987, Pentax Corporation of Japan unveiled the world's first AF SLR camera with a built-in electronic flash[3].

In 1992, Japan's Canon released the EOS5, the world's first single-lens reflex camera with eye control technology.

Who said that Japan is stronger than Germany in SLR technology, Japan is only stronger than Germany's sensor, but Germany is still powerful in optical system, such as Sony's lens, which is the technology of Carl Zeiss in Germany.

German SLR is better.

Sony's digital camera lenses are German Carl Zeiss lenses, and Panasonic digital cameras also use German Leica lenses. German things are good, but the best is high, and the Japanese ones are cost-effective, so Japanese brands will have a market. Other than that.

The lenses for both Canon and Nikon are Japanese.

Single Lens Reflex Camera (SLR Camera) is also known as a SLR camera. It refers to a camera that uses a single lens, through which the light hits the mirror, and the light is viewed through the reflex.

The so-called "single lens" means that the photographic light path and the framing light path share a lens, unlike the rangefinder camera or double reflex camera with independent lenses for the framing light path. "Reflective" means that a flat mirror in the camera separates the two optical paths: the mirror falls down during framing, reflecting the light from the lens to the pentaprism and then to the viewfinder window; When shooting, the mirror is quickly raised, and the light can hit the film or the image sensor CMOS or CCD.

Germany is good. Except** expensive thinks. Recommend Leica... German lenses, whether Leica or Zeiss, are the best.

Of course, Japan is good.

In the digital age, the German SLR feels that it is not used for people at all, nor is it used for the market, but is completely used to show off wealth.

Not to mention that there is not necessarily a qualitative difference between the effect of the German Leica SLR and the effect of the Japanese SLR, even if there is?

If there are only brands like Rolls-Royce in the car market, can the car industry still develop and survive? If an industry has problems with its own survival, then what's the point of talking about good and bad?
