Why can Yongnuo produce automatic lenses for Japanese cameras?

Let's take a look at the six shots of Yongnuo first.

1, Yongnuo domestic ultra wide-angle fixed-focus lens YN 14mm F2.8 (unit price 2899 yuan)

2. Yongnuo domestic wide-angle fixed-focus lens YN35mm F2 (unit price 530 yuan)

3. Yongnuo domestic large aperture lens YN40mF2.8n (unit price 490 yuan)

4. Yongnuo domestic large aperture AF lens YN50MM F 1.8 (unit price 280 yuan).

5. Yongnuo domestic telephoto lens YN85mm F 1.8 (unit price 998 yuan)

6. Yongnuo domestic long-distance fixed-focus lens YN100mF2 (unit price 9 10 yuan).

Therefore, it can be seen from the appearance that there is basically no big difference between Yongnuo and Canon. What is certain is that it borrowed Japanese technology, or it may be that Japanese patented technology has expired and Yongnuo can borrow it directly.

However, Yongnuo claims to be its own technology, which can be seen from the interview with Yongnuo photographic equipment marketing personnel on 20 17 (the following is an interview selection):

The lenses of 1 and Yongnuo have been on sale since 20 15. The first lens is a 50mm F 1.8 canon lens. From 20 15 to the end of 20 17, 35mm F2, 100mm2, 85mm F 1.8, 40mm2.8 and 14mm F2.8 were released continuously, which is the only automatic lens manufacturer in China. Yongnuo has also set the goal of making digital cameras in the future.

2. By the end of 20 17, among the six lenses of Yongnuo, 50/F 1.8, 35/F2 and 100/F2 were mounted by Canon and Nikon. So at present, 85/F 1.8 and 14/F2.

Yongnuo claims to have obtained a number of patented technologies in the research and development process. Encountered patent technical barriers from Japanese manufacturers. Yongnuo said that the original formulation was 50/F 1.4, which was eventually rejected due to Japanese patents. When Yongnuo took out the lens of 50/F 1.8 at an exhibition in Japan, it was once despised by the Japanese at the counter, thinking that they had stolen their technology. But Yongnuo believes that it is completely developed by strength and technology.

The lens of 4.50/F 1.8 was rejected by Japanese manufacturers when applying for a patent in China. Later, when reviewing, Yongnuo submitted its own report, and as a result, the patent was retained. Then from 2065438 to February 2007, Yongnuo went to Japan to participate in the exhibition, and Japanese manufacturers didn't go to Yongnuo counter to make trouble again, so Yongnuo thought that Japan could not be stopped by strength and technology.

We believe that many years ago, I learned German technology step by step to achieve today's optical achievements. If Yongnuo can stand on the patent, that is an advantage. Don't rush to criticize, I hope China will make greater progress in camera and optics.

If there is anything wrong with the answer to this question, please criticize and correct me. Welcome to discuss.

1 Yongnuo is a pure China brand.

Only Japanese manufacturers are allowed to shoot automatically, but only complete technical data are provided to domestic Japanese sub-factories, which is absolutely confidential. Yongnuo obtains data through reverse engineering, so Japanese factories can't say anything, because the technical data of the other side is not a patent, but a technical know-how, which should not be protected by law and should be reverse engineered!

Looking forward to the future, Yongnuo will join hands with DJI, Huawei and Xiaomi to make a single-camera SLR in China, breaking the camera market monopolized by Japanese companies by hook or by crook!

Yongnuo is a manufacturer of photographic products in China, which started with flash.

The company won the honor of national high-tech enterprise and has hundreds of product patents. The company has three factories and more than a dozen direct stores. Products are exported to Europe, America, Southeast Asia and other countries.

10 years ago, because of its good quality, Yongnuo's flash began to emerge, and it was known as the "domestic magic lamp", with high index, good color temperature, especially low price and good quality, and began to be loved by photographers.

Spend a fraction of the price of the original factory and bring a set of photographic light sources to add a lot of color to your work!

Especially later, Yongnuo's flash began to introduce automatic models compatible with Canon Nikon, supporting automatic exposure, autofocus, wireless fir, high-speed synchronization ... All functions of the original factory were realized!

This also laid a reputation and technical foundation for the later use of Nuo to enter the lens market.

Through the reverse engineering of flash, they probably mastered some technical details of lenses with similar technology, thus laying the foundation for domestic automatic lenses, but at present it seems to be limited to fixed-focus lenses, because the data of zoom lenses have not been reversed. Or does the zoom lens have the patent barrier of Japanese companies? It is not known for the time being.

But I believe that in the near future, Yongnuo will be able to overcome this difficulty and become an important lens vice factory, bringing more interesting and inexpensive lens products to China photographers.

I'm against the idea. Japanese introduced the China script and the four great inventions of the Chinese nation. The invention of the camera is not Japanese, and the automatic lens is not exclusively produced in Japan. Yongnuo uses China's optical technology to produce products, without fear of others gossiping. Just like the high-speed rail, China's Fuxing has left the Shinkansen far behind, right? .

Auto-focus technology has been developed and the software and hardware have been mastered. Another company in Shenzhen also has autofocus technology and developed autofocus lenses. There is also an automatic switching ring technology company that has mastered the software. Like the Japanese vice factory lens Longteng and Island.

The micro camera is also Xiaomi's, but it's not very good.

There are no technical obstacles to micro-cameras, the key is how the market is.

Optically, these two houses are not as high as the old frog and the domestic manual head.

Mainly fixed focus and zoom. Now only the old frog has one.

It can be played and reserved, but it is not suitable for production. Most people also play.

Any patent has a protection period. Once the patent expires, it is no longer protected by the patent and can be used by others. This has been confirmed in patent protection.

Canon SLR interface patent protection expires first. At that time, Yongnuo hit 50 F 1.8, which was only a time difference. In terms of lens quality, purple edge control is not as good as the original factory, and other performances are slightly better than the original factory.

Canon could only stare blankly, and finally quickly produced the third generation 50F 1.8 iron-butt spittoon to stabilize the market.

Because by reverse cracking the focusing system, especially Sony's, Sony opened the bayonet agreement itself. Although it is not authorized to Yongnuo, Sony is also willing. Sony is a high-priced lens, and people who will buy Sony G-head are not worried about this one or two thousand yuan lens to grab business. On the contrary, it can make up for the vacancy, and the rich lens group can attract people of all levels to buy.
