What do SLR digital cameras and LOMO cameras mean?

Photography, digital camera, camera lens, DSLR.

DSLR is a digital SLR camera, and its photosensitive device is CCD or CMOS.

DSLR digital camera refers to a single-lens reflex digital camera, that is, digital, single-lens, lens and reflex. Representative models in the market are common in Nikon, Canon, Pentax, Fuji and so on. This kind of camera is usually big and heavy.

For digital cameras, the photosensitive device of digital SLR is larger than that of ordinary digital cameras, so it will have better performance in color and brightness.

When shooting, the photographer sees the scene captured through the lens, so what the SLR camera sees is basically the same as what it gets.

Please refer to the "SLR" entry.

Appendix:

DSLR is called digital SLR in English, so is digital SLR camera. Many people only know DC (digital camera), but they don't know-DSLR, an important branch of DC.

In normal times, there will always be people who resist DSLR. These people can be divided into three types: one is people who have never heard of DSLR; One kind is people who have heard of it but have not experienced it personally; One is someone who knows the benefits of DSLR, but thinks it is a "high-end product" that is too professional. This part of people will inevitably look at DSLR with a sour grape mentality, put out a lot of weaknesses of DSLR to convince themselves and others, and try to convince themselves and others that a small camera is better.

In the past, DSLR was indeed a symbol of "professionalism" and "luxury", with a small user base. However, in recent years, with the continuous price reduction of DSLR brands, the entry-level DSLR has already stepped down from the altar, becoming smaller and smaller, becoming more and more popular, and popularization is an inevitable trend.

This paper aims to help people recognize the true face of DSLR, change people's opposite understanding of DSLR's "non-race" in the past, and clarify consumers' worries and worries about this kind of camera.

Not all DSLR are high-end products.

2006 was the year when the DSLR war broke out in an all-round way. In this year, Sony, Samsung and Panasonic entered the DSLR market collectively, while traditional manufacturers such as Olympus, Nikon and Pentax also came up with their latest low-priced products to deal with it, which intensified product competition on the one hand and greatly enriched consumers' choices on the other hand, further reducing the price of entry-level DSLR to freezing point. Although there are tens of thousands of high-end DSLR products, at present, entry-level DSLR sets with lenses below 6000 yuan and single bodies below 5000 yuan abound, and this price is no longer a high-end product.

This price has almost reached the defense line of high-end consumer digital cameras. It can be said that the price difference between DSLR and high-end consumer cameras is not obvious, which will directly shake the choice of some consumers who originally planned to buy consumer cameras. Although DSLR is slightly larger than high-end consumer cameras, the control and imaging quality of DSLR have made a qualitative leap. In addition, different lenses can be replaced as needed, which constitutes the absolute temptation of DSLR. Consumers choose the most consumer-grade cameras, 2000 ~ 3000 yuan. Although its imaging quality is extraordinary, it is different from DSLR.

Five fatal temptations of DSLR

1. Excellent imaging quality is the first reason why many consumers favor DSLR.

Because the photoreceptor area of DSLR is much larger than that of consumer cameras, and the pixels per inch are relatively greatly reduced, the performance of DSLR far exceeds that of consumer cameras in terms of latitude, resolution and high sensitivity. The size of the photoreceptor is also the last factor that affects the sales of consumer cameras. Manufacturers often use other indicators such as high pixels to distract users. In fact, the size of the photoreceptor is far more important than the number of pixels. The maximum size of the photoreceptor of consumer cameras is only11.7 inches, while the photoreceptor area of SLR is mostly APS-C (23.7mm× 15.6mm) to full size (36mm×24mm), which is the same as that of 135 negative.

2. The shutter of 2.DSLR is a pure mechanical shutter or an electronically controlled mechanical shutter. The shutter has a very short time lag, and it can be imaged after pressing the shutter, which is a sharp weapon for capturing pictures.

The start-up speed of DSLR is only a few hundred milliseconds, and the continuous shooting speed is also very fast. Consumer cameras, on the other hand, are pure electronic shutters, which has a serious shutter lag problem. This weakness can be called the weakness of consumer cameras, so you can shoot still life, but it is not suitable for capturing moving objects-the image you get is often not the action when you press the shutter.

3. The SLR camera looks bright through the lens, and the picture you see is what you will shoot. Transparent light makes it easier to observe when focusing.

Consumer cameras take pictures through photoreceptors and LCD, so there will be some errors in the observation of brightness and color, which is not easy to detect, and it is even more difficult to see the picture clearly in the dark. Even if there is an optical viewfinder on a consumer camera, its optical path does not pass through the lens, so there is parallax.

The lens of 4.4. The DSLR can be changed according to the shooting theme. The lens of consumer cameras cannot be replaced, and the lens quality is much worse than that of DSLR.

5.DSLR has many manual functions.

DSLR can easily zoom manually and set shooting parameters manually. , and you can take some special shots (such as shooting fireworks with door B). But many consumer cameras are automatic (especially card machines). Most cameras have no manual zoom ring, so they can only zoom automatically by motor. Because the speed of zooming is slow, many shooting opportunities will be lost. Many people think that automation is better than manual operation, which is really a misunderstanding. Cameras with automatic function but no manual function are often low-end cameras, because the accuracy and speed of automation are far less than that of manual operation.

Do you really need DSLR?

If you just use a camera to shoot scenery, "come here for a tour" and record family entertainment, there is really no need to buy a SLR. Although DSLR is good, it is not suitable for everyone because of its price and weight. In addition, even if you have a DSLR, it doesn't mean that you can take good photos from now on. Because DSLR is more powerful, you need to learn more about photography to apply it well. If you use automatic transmission all the year round, the advantages of DSLR will be greatly reduced.

In addition, if you belong to the following situations, then you really need a DSLR.

1. If you have high requirements for image quality, please choose DSLR.

In contrast, consumer cameras will let you down. The simplest example is that the shallow depth of field effect (blurred background) of DSLR is beyond the reach of consumer cameras.

2. If you often take portraits, please choose DSLR.

Although the images taken by consumer cameras are very clear, we must correct the understanding that a good photo is clear and blurred in Jiao Wai, but not all of it.

3. If you have special requirements for snapshots and need faster response, please choose DSLR.

If you use a consumer camera to capture a moving scene, it will be difficult for you to capture the moment you want because of the lag of the shutter, and all you capture is the action you don't need. This result will directly lead you to lose confidence in "snapshot" photography and only shoot still things.

There is another point that friends who want to contact SLR should know.

Three nouns that DSLR novices are most concerned about.

1. Coke section

People often ask how many times the lens of a DSLR camera is. Please note that this is an extremely amateur question. When the digital camera was just born, because the focal length of the lens was pitifully small, in order to distinguish it from the focal length of the traditional 135 lens, we only talked about the zoom multiple and didn't talk about the actual focal length, which would make people forget that the focal length was small and the photosensitive area was small, which was actually a distraction. But DSLR uses the lens of 135 camera, which is usually based on the actual focal length, such as 17-85mm, which means that the zoom range of this lens is17 mm ~ 85 mm. If you insist on asking how many times the lens is, then this lens is 5 times zoom. The reason why this conversion is unscientific is that since the DSLR can replace the lens, if it is replaced with a lens of 70-200, the zoom factor is less than 3 times, but the base starts from 70mm, which is actually farther than the previous lens with 5 times zoom. Even for consumer cameras, the final result brought by optical zoom magnification is related to the starting base, and not all the fields of view with the same magnification are the same, so the magnification of consumer cameras is also a vague concept.

2. Original lens and sub-factory lens

Camera manufacturers such as Canon, Nikon and Pentax, which produce DSLR fuselage, are called original lenses in order to correspond to the lenses produced by their DSLR systems. And some professional lens manufacturers provide lenses with different camera interfaces, so that consumers have more choices, such as lenses with interfaces such as Canon, Nikon and Pentax produced by manufacturers such as sigma, tamron and tokina, commonly known as sub-factory lenses. Of course, it seems inappropriate to refer to these professional lens manufacturers as sub-factories, because many lenses produced by these professional lens manufacturers have the same quality as the original lenses, but the prices are much less than the original lenses, making them the first choice for many photographers who are not well off.

3. The focal length conversion rate

At present, the photoreceptor size of mainstream DSLR is much larger than that of consumer cameras, but it still can't meet the specifications of 135 film (unless it is a full-frame camera). Therefore, the imaging range of the lens with 135 camera will be different from that of 135 camera, and it is usually multiplied by 1.5 times (Nikon product) or 1.5 times. For example, Nikon DSLR is equipped with a 50mm lens, and its viewing angle is equivalent to the viewing angle when the focal length is 50 mm×1.5 = 75 mm. However, the optical characteristics of a certain focal length will not change because of the same viewing angle. Even the "equivalent to ××mm~××mm of 135 camera" declared by consumer cameras in the publicity only means that the viewing angle is equivalent, and the optical effect cannot be "equivalent".

LOMO

Lomo is an abbreviation. In 1950s, there was a factory in St. Petersburg, Soviet Union, which specialized in producing military optical lenses. It is called Leningrad Optical Instrument Factory, which is the largest optical instrument factory in Russia. LOMO LC-A is a 35mm automatic exposure paraxial camera developed and produced by this factory in the former Soviet Union. Now Lomo has a new meaning. Lomo is to make our life magical and open, and to make our life open and magical. Lomo= Rama, Le Mo, naked cat ... Le Mo! Although there are many translated versions, in Hongkong and Taiwan Province Province, Lomo fans have given it a proper Chinese name-Le Mo-which makes us touch life happily!

LOMO past life

[Edit this paragraph]

LOMO camera was born in Leningrad optical-mechanical joint venture in 1950s. It is a small simple camera used by the spy department of the former Soviet Union. Because of its special application field, it can shoot day and night without blinking. Portable low-tech 35 mm automatic exposure paraxial camera. Originally it was a Minox imitating Lycra. At that time, this camera was not very popular. There was only a simple B door without aperture, and the imaging quality was not high, and the dark angle of the photo was relatively large.

Because the camera is particularly sensitive to red, blue and yellow, the photos developed with positive films are extremely bright in color.

Regarding the formation of LOMO art, we should first mention Lomo LC-A, which is the origin of Lomography. Lomo camera was originally a product of the former Soviet Union. 1manufactured by Leningrad Institute of Optics and Mechanics in the early 1980s. It is a "Yangchun fool camera" made for the needs of the public.

Lomography is gradually emerging.

The Lomography Society makes the Lomo camera appear the myth of regeneration, but at the same time, it must be ensured that it can develop in the long run. Lomographic began to rise in St. Petersburg in 1982. Requiring Lomo manufacturers to mass-produce spy cameras not only benefits the people, but also brings honor to the Soviet Union.

The Lomographic craze began in St. Petersburg in 1982. On a sunny morning, General Korniczky put a small Japanese camera (Cocina CX-2) on the table. His close comrade-in-arms panfilov (director of Lomo Soviet Optical Factory) carefully looked at the camera and found that the lens was clear, the sensitivity was extremely high and the appearance was solid. Two people noticed its characteristics and potential, and immediately studied how to improve the design. I hope to produce a full-featured all-weather camera, with the purpose of providing fun for the people of the whole Soviet Union and recording the socialist life and the glory of the motherland. Finally, Lomo LC-A was born, and millions of cameras sold out quickly. People from the Soviet Union, Vietnam, Cuba and East Germany began to participate in the 1980s.

LC-A is a compact automatic camera, which provides daily photography tools for the public. But there is great value hidden behind simplicity: Minitar 1 lens designed by Professor Radionor produces bright colors under wide-angle lens. Generally, it only appears in the automatic sensing function of expensive professional cameras, which makes Lomo can be used in any environment and can create outstanding line effects at night. A hollow life, a hard and clean metal structure, and an intoxicating Soviet atmosphere.

The appearance of Lomo LC-A

Now people in the Soviet Union, Vietnam, Cuba and East Germany are still living under capitalism. At the same time, two Austrian Vienna art students, WolfgangStranzinger and MatthiasFiegl, went to Prague for a holiday in the early summer of 199 1 and tasted Czech democracy for the first time in a scorching atmosphere. Due to the popularity of high-tech electronic cameras in Asia at that time, LC-A has been discontinued, and the rest can only be found in old camera shops. Two Vienna students were so excited that they bought an old Lomo camera-LC-A in a second-hand shop.

On the bright streets of Prague, they took a snapshot: from the top of the head, from the back, from the bottom ... The whole trip ended with beer, vodka and LC-A. After returning to Vienna, they took the film to the supermarket for development, and they were very shocked after seeing the photos! The bright, happy and hazy effect has injected a new feeling into Czech face, and the image effect has never been so enjoyable!

1992, the official organization of LOMO: lomo graphic society was established in Vienna. The purpose is to release information about Lomography to the whole world.

LOMOgraphy is not only a platform for communication among LOMO enthusiasts, but also an organization that distributes and sells Lomo cameras online. This is what everyone calls "LOMO official".

Lomo has gradually become the new favorite of fashion, and the secret of Lomo's happiness has spread rapidly among young people in Europe, becoming the new favorite of underground art and cultural circles.

Unfortunately, after privatization, Leningrad Optical and Mechanical Bureau, which produces Lomo cameras in the Soviet Union, will abolish the loss-making camera department and schedule 1996 to stop work and close the factory. Hearing this, the two men quickly asked the factory that had been closed for a long time to reopen and then produce Lomo automatic cameras.

1996, the two men persuaded Putin, then the mayor of St. Petersburg and the general manager of Leningrad Optical Instruments Union, to continue to produce the "super fool camera", which is not only beneficial to their national economy, but also important for promoting art and culture.

The Lomo revolution has begun. This factory produces 2000 Lomo cameras a month, but the price has risen from $30 for 1995 to about $200. (This is one of the reasons why there are different versions of LCA, but in April 2005, LCA was completely discontinued! )

After the student and his friends posted photos of the banquet or daily scenes and objects taken with LOMO on the kitchen wall, they started the "LOMOWALL" exchange activity.

1997, the first LOMO world congress was held in Madrid, Spain, and 15000 photos were displayed side by side in mosaic style. The whole exhibition wall is108m long. Become the new favorite of underground art and culture.

Today, if you still think that "fool photography" means backwardness, then you are far behind the times, because this "LOMO casual photography style" is very popular in Europe and Japan! Shoot whatever you want, shoot continuously, ignore the orthodox photography rules, and only pay attention to personal randomness and authenticity. Maybe you don't think this is an artistic act, but an emotional vent in adolescence. But, you are wrong! This is art, a new photography art!

These promoted and secretly spread Lomo cameras and the people who took impromptu photos with them are "Lomoer". Countless Lomo people all over the world, from Cuba to Japan and Vietnam, are saying, "LOMO is not only a creative photography, but also a way of existence." Lomo's creative philosophy is: "move quickly, don't think too much, open your eyes to the surrounding environment, absorb more and enjoy communication." Lomo, which is composed of creativity and motivation, is open to everyone who is curious and loves to press the shutter. Through Lomo, art gradually permeates our daily life.
