What's the difference between Zeiss glasses and ordinary glasses?

Zeiss is currently the top three lens manufacturers in the world.

Difference 1: membrane. Zeiss membrane is divided into lotus series and diamond Rubik's cube series. , with wear resistance, transparency and special use. This kind of thin film technology and manufacturing process can't be achieved by ordinary lenses.

Difference 2: Zeiss functional glasses, many functions are original by Zeiss, and then copied by ordinary lens manufacturers.

Which series of Zeiss glasses is better?

Zeiss lens is world-renowned for its high-tech content and excellent quality, and its brand image is impeccable. However, due to its high price, the consumer groups are limited to wealthy circles and successful people in the upper class.

Outstanding brand history

The German Zeiss Company, the world authority in the field of optics, was founded in 1846 by Mr. carl zeiss and Mr. Ernie Abbe. The quality of Zeiss products has been highly praised by professionals and the market for many years. Cutting-edge technology, telescopes, microscopes, professional camera lenses, astronomical telescopes, planetariums, ophthalmic instruments, high-precision computer surgery instruments, the Apollo spacecraft landing on the moon, there are more than 20 high-tech fields without Zeiss.

Einstein, the greatest scientist in the 20th century, wrote a letter to a friend at 1925, emphasizing that Zeiss lenses represent the highest quality and reliability, and that "... it is so difficult to grind the original accuracy to one ten thousandth, and only Zeiss can do it. Therefore, each gyroscope must be sent to Zeiss for stage grinding ... "

In Germany, Mercedes-Benz, Audi and other world-class car factories, in order to ensure that every part of the rigorously designed car body is accurate and achieve the perfect and tight assembly state of the car body, three-dimensional measuring instruments made by Zeiss are used to detect the car body, and only Zeiss can meet its requirements for perfect quality. The lens polished by Zeiss Company is a symbol of quality. All camera lenses that use Zeiss lenses are expensive. The high-end lenses and camera equipment of Hvasselblad (Suha), Contex (Kandy) and SONY (Sony) in Japan all use Zeiss lenses. Last year, Japan published a book on photography, which means that only Zeiss is the best! 1988 Germany * * * issued a 10 Deutsche Mark coin with the head of Mr. Zeiss as a pattern to commemorate the great achievements that Mr. carl zeiss brought to the optical field.

The precision grinding error is extremely low.

The accuracy and error of Zeiss lens are incredible. Take the smoothness of lens polishing as an example: if we enlarge the lens with a diameter of 70 mm into a lake with a diameter of 26 kilometers, the water ripples on the lake will not exceed 0. 1 m!

The surface of Zeiss lens is accurately divided into 50000 points, which represent the combination of 800 mathematical equations. The allowable error of each point is strictly controlled within 0.65438 0 micron. Such strict quality management ensures the perfect quality of Zeiss lenses, and each lens is a perfect work of art.

Strictly controlled dispersion coefficient (Abbe number)

Abbe number is the dispersion coefficient. Everyone knows that light can be decomposed into red, orange, yellow, green, cyan, blue and purple through a prism. The dispersion coefficient reflects the splitting ability of the lens. The dispersion phenomenon was first discovered by Mr. Ernes Abbe, one of the founders of Zeiss Company. He set a defined independent variable for the dispersion coefficient, so the dispersion coefficient is called "Abbe number".

For ophthalmic lenses, the lower the dispersion, the better. The larger the dispersion coefficient, the better. If the dispersion is strong, there will be prism effect, which will make people feel colorful and cause dizziness and brain swelling. Therefore, the dispersion coefficient has become one of the important indexes to measure the quality of lenses. Zeiss lenses pay special attention to the control of Abbe number, and the dispersion is much lower than other brands of lenses with the same refractive index, showing perfect vision.

Extremely high lens transmittance

The strict quality control of Zeiss lenses ensures the extremely high transmittance of the lenses. The light transmittance of Zeiss resin lens with reflective film is 99.4%, and the light transmittance of glass lens is incredible 99.8%. People can no longer feel whether they are wearing glasses or not. With such high precision, only aerospace science and technology have practical value. Only Zeiss, a leading figure in the field of optics, has such high standards and requirements and brings you extraordinary enjoyment.

Perfect multi-wavelength lotus coating technology

In order to ensure the best imaging quality of the lens, at the same time, make the service life of the lens longer and reflect the use value, Zeiss adopted the latest coating and material design, unique special technology and integrated nanotechnology, and launched the Lotus Film series lens. The revolutionary waterproof, wear-resistant and dirt-resistant film layer makes the contact angle between water droplets and the lens surface greater than 1 10 degrees. When water drops splash on the lens, they will slide down like hitting the lotus leaf, keeping the lens clean at all times.

The coated lenses all passed the five-layer fastness test:

Exposure to high temperature for 6 hours. ......

How about the quality of Zeiss glasses? Have you ever worn them?

German Zeiss is a well-known brand of glasses, binoculars and lenses in China and a household name in Europe. The first spectacle lens in the world was invented by their family, and I am a well-deserved world optical leader. I brought my own Zeiss Sharp, which is clearer and better than other lenses. However, German goods, like BMW and Mercedes-Benz, are always a little expensive and worth the money.

How to check that the lens is from Zeiss, Germany?

Carl zeiss carl zeiss lens origin difference AEG AEJ MMG MMJ

Transferred from leelinfeng's blog

But anyone with a fever will come into contact with it.

Friends of Zeiss lens will meet it, and the lens of the same specification has AEG MMG AEJ.

MMJ and other different models. Which one to choose is really a headache. AE mirror and MM mirror are easier to understand, AE mirror can only give priority to aperture, and MM is the so-called multi-.

Mode, in addition to aperture priority, you can also use speed priority and automatic program function. G stands for made in Germany and J stands for made in Japan. So, will G mirror and J mirror be different in specific imaging? Although the official claims that there is no difference between the two, among many enthusiasts, this statement is different. What's the difference between German and Japanese? I wonder if it can be summarized from the following aspects.

1 coating of lens

When you get the lens, the first thing you notice is the difference between the German version and the Japanese version, which is also the most discussed topic. Generally speaking, the coating of German version is mostly dark purple (there are also tiger glass, green, blue and other colors), but compared with Japanese version of the lens, especially wide-angle lens, green coating is more common. Different specifications of lenses show different coating colors, and lenses of the same specification but different batches still show different coating colors. It is hard to imagine that the formula of Zeiss T* coating changes so frequently, so I would rather believe that the difference of lens color comes from the difference of lens glass material. Another way of saying this is that although the coating formula is the same, the T* coating in German version is slightly thicker than that in Japanese version. It is very simple to make measurements. I believe there is no need to use expensive equipment such as AFM, AFM and SEM, and a simple surface shape tester will do. However, it seems that scratching two lenses for this is not worth the candle.

Legend has it that the lens starting with the serial number 58 used the same glass as Cantareil Cox. Lens lovers of Contaflex who play with the elderly must be very familiar with it. that

P85T* 1.4 is more expensive than contax's commemorative mirror P85/ 1.2, and its strength can be imagined (scarcity is also one of the reasons). Glass has a great influence on lenses. German-made lenses are particularly particular about this. Japanese lenses are usually designed first and then made. However, the actual optical index of glass deviates from the design value, so the influence of this deviation on imaging is inevitable. However, German-made lenses, especially those with Apo level, such as Hasselblad's 300/2.8, are flat.

55/ 1.2 and so on. Buy glass first, test the parameters, and then design the lens according to the parameters. Although this high-cost operation mode ensures the quality of the lens, it is inevitable that the price is high and the output is limited.

From the perspective of glass refining, Japan is wet and Germany is dry, so the water dissolved in the glass during the refining process is of course Japanese glass. Obviously, from the production environment, the glass made in Germany is superior in light efficiency. Furthermore, the problem of environmentally friendly glass. Early glass contains lanthanide transition metals such as lead and thallium, which is beneficial to imaging (for example, lead oxide can improve optical refractive index and dispersion, and arsenic oxide can clarify bubble function, etc.). I am in favor of protecting the environment and reducing pollution, but as a photographer, I have to feel embarrassed about losing a batch of optical glass with excellent performance. Recently, both Germany and Japan have adopted environmentally-friendly glass (such as Hasselblad CFI series lenses). Although many remarkable achievements have been made through new research and development, personally, the characteristics of non-environmental glass are still irreplaceable. Think about how confident and powerful Zeiss was when he created P 135/2 with only five lenses! The German version of Zeiss of the same specification is earlier than the Japanese version. If you want to have non-environmental glass lenses, it is inevitable to find a German head. In addition, the side of the early German lens was not treated by extinction, which was easy to cause stray light and was easily eaten in the backlight, thus reducing the contrast. On the other hand, the yellow mirror in Germany is also because of this. Sunglass has improved in this respect, and it is even better in anti-backlight.

3-hole structure

This is an old topic. G version of the lens is generally serrated. When the aperture is closed at 1-2, the light spot is serrated when there is a light source behind it, and the sawtooth disappears when the aperture is closed at 1-2 or above. but

The MMJ version is a standard octagonal structure with no fuzzy background. ......

Is there a difference between Zeiss lenses and ordinary glasses?

The lens of Zeiss is really high! /kloc-More than 0/00 years ago, the world's first axisymmetric lens with focus imaging function, and the anti-reflection coating technology of the lens were all invented by Zeiss, which can be said to be the inventors of modern German glasses!

Zeiss lenses have many advantages-

1, the grinding degree is the most accurate: 1925 Einstein wrote to praise Zeiss's grinding accuracy to his friends.

2. Optimal curvature combination: Zeiss lens is designed according to eye ergonomics, and the internal and external curvatures of the lens are calculated by computer to design the optimal curvature and achieve the best imaging quality.

3. Maximum imaging quality area: The good imaging quality area of Zeiss lens is 56mm, reaching the maximum imaging quality area.

4, the softest film color Zeiss lens has the softest reflective color, which is more beautiful and clear.

5. Founder of glasses industry standard-Abbe number: One of the founders of Zeiss is physicist Dr. Abbe, the inventor of Abbe number. Zeiss lens has high Abbe coefficient, low dispersion and very stable imaging quality.

6. Thickness of safety center: the thickness of Zeiss lens center is resin 1.2mm and glass 1.0mm, so as to ensure the safety of visual quality.

How about Zeiss glasses? What are the characteristics? Want a pair?

Zeiss' glasses? German brand on the tall platform, 100 years ago, the world's first axisymmetric lens focused on imaging, and the anti-reflection coating technology of the lens was invented by Zeiss. It can be said that Zeiss in Germany is the inventor of modern glasses! Zeiss has nothing to say about professional standards such as grinding degree, curvature combination, imaging quality area and Abbe number.

There are many kinds of Zeiss lenses, including digital lenses specially designed for users of digital products, those specially designed for office use and those specially designed for foreign drivers. There are ultra-high-order lenses customized according to your eye habits by using Zeiss patented freeform surface technology, and the price ranges from more than 500 to 1 10,000, depending on what you ask. There are too many styles! The key is to find out whether that store is authorized by Zeiss. You'd better buy it in a bigger store.

What about the German Zeiss lens?

As far as I know, the German Zeiss lens seems to be the best lens in the world at present.

If you want to match Zeiss lenses, it is recommended to choose a regular optical shop. Shenzhen has Hong Kong standard glasses, doctor glasses, Bao Dao glasses and Asian glasses. . Wait a minute.
