What are the main types of cameras?

What are the classifications of cameras? What does a SLR camera mean?

The detailed classification of cameras is as follows:

1. Depending on the imaging medium of the camera.

It can be divided into film cameras, digital cameras and Polaroid cameras. Film camera mainly refers to the equipment that images through lens and records images with film.

Digital camera is a photographic equipment that uses semiconductor photoelectric coupling devices and digital storage to record images. It has the characteristics of convenient use, convenient photo transmission and convenient storage. Polaroid camera, also known as primary imaging camera, directly exposes images on special photographic paper, and can see photos in one minute, which is suitable for taking pictures.

2. According to the film and picture size used by the camera

It can be divided into 35mm camera (often called 135 camera), 120 camera,10 camera, 126 camera, medium camera, large camera, APS camera and miniature camera. 135 camera uses 35mm film, and its standard frame is 24mmX36mm. Generally, 36 or 24 shots can be taken per film.

3. According to the appearance and structure of the camera

It can be divided into viewfinder camera and SLR camera (SLR camera). In addition, there are folding cameras, double-lens reflex cameras, rangefinder cameras, conveyors, landlines and so on.

4. According to the shutter form of the camera

It can be divided into lens shutter camera (also known as center shutter camera), focal plane shutter camera and program shutter camera.

5. According to the function and technical characteristics of the camera.

It can be divided into auto-focus camera, manual exposure camera and automatic exposure camera. In addition, there are shutter priority, aperture priority, program control, double priority, electric film winding (automatic film winding and rewinding) camera, automatic focus (AF) camera, date back camera, built-in flash camera and so on.

Sometimes it can also be divided according to the use of cameras, such as professional cameras and consumer cameras (fool cameras), one-step imaging cameras and stereo cameras; Sometimes it can also be divided into zoom or bifocal cameras according to the characteristics of the lens. In fact, a modern camera often has many characteristics, so it should be defined comprehensively.

It can be roughly divided into five categories: SLR cameras, digital cameras, micro-cameras, film (card) cameras and sports cameras.

SLR camera refers to a camera that uses a single lens, through which light shines on the reflector and takes a view through reflection. The so-called "single lens" means that the photographic exposure light path and the framing light path share a lens, unlike the paraxial camera or the double-reflex camera, the framing light path has an independent lens.

The difference between micro-single and SLR, card machine and digital machine;

1, micro-single and SLR

The main difference between micro-single and SLR is that micro-single has no reflector, so it is relatively smaller and more portable. The advantages of SLR optical imaging are fast focusing and quick response, which is suitable for snapshot.

Micro-single lens is smaller in size, and its imaging is basically comparable to that of digital SLR, but the response of framing is slow, which may bring difficulties to sports shooting. The size of the other lens is also smaller, which is smaller than the SLR structure, so the imaging of the lens is not so good, but it is no problem to meet the needs of home.

2. Microfilms and cards

Micro-single can be understood as a card machine that can change lenses, but the function of micro-single is stronger than that of card machine, and the picture quality is better, but the requirements for operation are higher, which can be understood as a small version of SLR.

But in some operations, theoretical knowledge can almost communicate with SLR. If you have a certain photography foundation, or have a week-long photography, it is recommended to have a micro-list, but if you are just visiting here, you should stick to it and be smaller.

3, micro single and digital

The biggest difference is that the size of CCD is different. Digital cameras are usually called card machines, mainly because CCD sensors are small in size and high in pixels per inch, while micro-single sensors are usually more than four times the size of CCD of digital cameras, and the single pixel area is large, so the imaging quality is high.

Classification:

1, SLR camera

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.

2. Miniature single camera

Micro-camera has two meanings: micro-camera, compact, single-lens camera and replaceable single-lens camera. That is to say, this word means that this kind of camera is small in size and its imaging quality is similar to that of SLR. That is to say, micro-camera with SLR performance is called micro-camera.

3. Card camera

There is no clear concept of card camera in the industry. Only those small shapes, relatively thin bodies and ultra-thin and fashionable designs are the main standards to measure this kind of digital cameras.

4, telephoto camera

A telephoto digital camera refers to a model with a large optical zoom factor. The larger the optical zoom factor, the farther the scene is photographed. Representative models include Minolta Z series, Panasonic FX series, Fuji S series and Kodak DX series.

Advantages and disadvantages of digital cameras;

superiority

1. You can see the picture immediately after taking a picture, which provides the possibility of remaking the dissatisfied work immediately and reduces the occurrence of regrets.

Just pay for those photos you want to develop, and other unnecessary photos can be deleted.

3. Color reproduction and color range no longer depend on the quality of the film.

4, the sensitivity is no longer fixed by the film, and the photoelectric conversion chip can provide a variety of sensitivity choices.

5, the product structure is relatively simple, the appearance is more exquisite, and the product is more and more portable.

6. The digital camera is simple, clear and easy to use.

disadvantaged

1. Due to the conversion between imaging elements and image processing chips, the imaging quality is less layered than that of optical cameras.

2. Due to the different technologies of image processing chips from different manufacturers, the colors of the imaged photos are different from the real ones.

3. Due to the lack of core technology in China, the later use and maintenance costs are high.

What are the types of cameras?

The camera can shoot all kinds of beautiful pictures, so that people can keep these beautiful things. They are the equipment that tourists and photographers carry with them. Since the development of cameras, many different styles have been introduced. So what are the types of cameras? The following is an introduction about the types of cameras I brought to you. Welcome to reading.

What are the types of cameras? First, according to the core sensing materials used.

According to the core sensing materials used, it can be divided into film machine and digital camera. Film machines are on the verge of elimination. At present, only the top commercial films are practical, and the shooting quality is exquisite and tolerant, but the film material is expensive and inconvenient to develop. Digital Cameras Most cameras are like this now, which can be used many times. The photos are all digital and easy to use.

What are the types of cameras? Second, the division of framing methods.

Camera framing methods can be divided into double reflex, SLR and paraxial. At present, SLR is the main camera, and the other two cameras will have parallax, which is more obvious when the distance is closer.

What are the types of cameras? Three: according to the professional nature.

According to the professional nature, it can be divided into consumer-grade machines and professional cameras. Consumer machines mainly include fool machines and card machines. These cameras are relatively cheap, easy to use, poor in metering and focusing, and poor in imaging quality. Professional cameras are mainly SLR, with excellent image quality and accurate focus, but the price is relatively high.

Introduction of digital camera types

Digital cameras can be divided into medium format, SLR, single camera (Sony can be divided into micro single camera and single camera), paraxial camera, SLR-like camera and so on.

Medium format camera: This is an advanced professional camera, and the size of photosensitive element is larger than that of Quan Huafu. The price is more expensive. Mainly Hasselblad, Freescale, Pantex and other brands.

SLR cameras: From large to small, the frames in SLR cameras can be divided into Quan Huafu, APS-H, APS-C and 4/3 frames. Generally speaking, the larger the frame, the better the picture quality, but the corresponding cost will also increase.

Single-lens camera: A single-lens camera is a camera with variable lens, with a mirrorless system or a fixed mirrorless system. Sony is divided into micro single camera and single camera, and its formats are mainly APS-C format and 4/3 format, which belong to the category of consumer cameras.

Paraxial camera: Using optical framing system, there will be parallax between framing and actual shooting, and the imaging quality is good.

SLR-like camera: looks like SLR, mirrorless system, electronic viewfinder. The operation of this SLR is similar, but the lens cannot be changed.

At present, digital cameras are the main products in the market, including high, medium and low grade. Users can choose their own camera according to their actual needs.

What kind of camera do you have?

1, according to the core sensing material used: film machine (top commercial photography is still used at present, which is characterized by fine picture quality and high tolerance, but film is expensive to buy many times and is not convenient to develop); The other is digital camera (at present, most cameras belong to this category, which is characterized by multi-use, digitalization, convenience, tolerance and improved treatment)

2, framing mode: double reverse, SLR, paraxial. Most of them are SLR at present. The other two will have parallax, and the closer the distance, the more obvious it will be.

3. Professional nature: consumer machines (also known as fool machines and card machines, which are cheap and easy to use, but have poor manual performance, poor metering and focusing functions, and poor image quality), professional cameras (SLR has basically become synonymous with it, with good image quality and quick focus, but with high price and large investment in various bodies and lenses in the later stage).

Let me start with the classification of digital cameras.

1, divided by frame: large format-medium format-Quan Huafu -APS-H format -APS-C format -4/3 format-small sensor (mainly11.6-1/2.3 for card machines).

Theoretically, the larger the frame, the better the picture quality, but the cost will increase relatively.

The above frames are from big to small.

The first two are mainly commercial photography and super photographers.

Third, the best choice for professional photographers in current civil consumption.

The fourth one belongs to Canon, which is the frame for our own professional camera. It is rumored that this frame will be cancelled.

The fifth is the main frame of the current SLR, and most of the SLR cameras we see every day are this frame.

The sixth is the format used by the 4/3 camp. The main manufacturers are Panasonic, Olympus (these two are more important) and Fuji.

The seventh category is the framework currently used by card machines.

2. According to the model.

SLR such as Nikon D* series and Canon D series are all listed here. These are in APS-C format.

E series of Olympus. This is in 4/3 format.

Single grid/micro grid, including APS-C format (mainly Sony NEX series and Samsung NX series) and 4/3 format (mainly Panasonic GF series, Olympus EPL series and EP series), is very hot at present.

Not to mention the traditional telephoto machines such as Canon SX30, Nikon P500, Fuji HS22 and Panasonic FZ 100, among which Fuji has the most tidy product line.

It is characterized by comprehensive functions, strong manual operation and large zoom, but the picture quality is not good. In essence, it is an extension of the function of the card machine to meet the needs of some people who are short of money but want to practice their hands.

Card machine (portable telephoto lens is the most active one at present) has a small body and a larger zoom factor, but as I said before, the picture quality is not good.

The flagship card machine has good workmanship and operability.

That's about it, right?

No, just asking.

I hope it helps you.

What are the classifications of cameras?

A camera, referred to as a camera for short, is a device that uses the principle of optical imaging to form an image and records the image with a negative. Many devices that can record images have the characteristics of cameras. Let me introduce the classification of cameras to you.

1, camera classification: according to the way of framing.

(1) Single lens reflex cameras (SLR cameras) 120 and 135 all have SLR cameras.

Features: the lens is detachable, and the framing is ignored.

(2) A dual-lens reflex camera is usually a 56×56mm 120 camera.

Features: the lens is arranged up and down, the top is used for framing and focusing, and the bottom is used for photography.

(3) Paraxial camera

2. Classification of cameras: according to the degree of automation.

(1) Full-manipulator camera

This camera doesn't have any automatic function. Whether it is exposure, focusing or film rolling, it must be operated manually.

(2) Automatic exposure camera

In addition to the metering system, this camera can also automatically control the aperture and shutter mechanism according to the metering results to achieve correct exposure. According to the different automatic exposure methods, it can be divided into aperture priority, shutter priority and program. Journalists all use this kind of camera.

(3) autofocus camera

Also known as AF camera, it can automatically change the focus of the lens according to the shooting distance, so that the main scene can be imaged clearly. It can save the photographer's focus when shooting, which is not only beneficial to concentrate on shooting, but also beneficial to capture in an emergency. It is the mainstream camera of news photography, such as Nikon F 100, F6, F5, Canon EOS 1, EOS3, etc. When shooting, the main body is placed in the focus area of the viewfinder, and the shutter is half pressed. The camera lens is driven by the motor to expand and contract back and forth, and it is controlled at the corresponding position to automatically make the image clear. Some of these high-end cameras also have autofocus and lock functions.

(4) Digital camera

Digital camera is the combination of digital technology and camera principle. It uses an electronic image sensor to convert light into charge, and then converts analog signals into digital signals, which are compressed and stored on the memory card in the camera.

Types of digital cameras: consumer and professional (SLR). Application in news photography (it has become the mainstream at present).
