What are the functions of camera body?

1, according to the core photosensitive material used: film machine (top commercial photography is still used at present, which is characterized by fine image 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.

Classification of SLR cameras

SLR cameras can be mainly divided into the following three categories.

1, entry-level digital SLR camera

As the name implies, this camera is mainly aimed at entry-level users. This kind of camera is light, easy to carry and cheap. In addition, its performance not only retains the basic functions of digital SLR cameras, but also provides users with a variety of scene shooting modes, which can help beginners learn and improve their shooting skills step by step on the basis of ensuring smooth shooting.

2. Quasi-professional digital SLR camera

As far as the camera body is concerned, more metal elements are incorporated, and the camera body has better stability and reliability. In particular, they have more reliable dust-proof, frost-proof and splash-proof performance, which enables this camera to cope with more extreme weather conditions and environments.

3. Professional digital SLR camera

Compared with other digital SLR cameras, this camera is equipped with many top technologies in the field of digital SLR cameras, and it is the king in the field of digital SLR cameras in terms of focusing performance, metering performance and other aspects.

Matters needing attention in purchasing SLR cameras

1, image sensor area

The area of the image sensor is the main factor that directly determines the imaging quality. Whether it is CCD or CMOS, the larger the area, the better.

2. Pixel size

At present, mainstream SLR digital cameras should generally be more than 6.5438+million pixels, but the bigger the pixel, the better. In the case of the same image sensor area, the larger the pixel, the worse the imaging quality.

Step 3: lens

There are two ways to sell SLR digital cameras: one is to sell the body separately, and users need to match their own lenses; The other is a set machine, which is equipped with a lens in addition to the fuselage. However, the matching lens grade is not too high, which is a relatively cheap product, but the kit is cheaper and more affordable than buying the same body and lens separately, which is suitable for users with insufficient funds.

What kind of cameras do you have?

There are both digital cameras and film cameras, but film cameras are rarely used now. Digital cameras mainly have the following types:

1, card camera: portable and low in price, basically meeting daily needs;

2, SLR camera: excellent imaging, lens replacement, professional first choice;

3, telephoto camera: with multiple optical zoom and certain manual function, suitable for creative use;

4, micro single camera: interchangeable lens, SLR quality card is light.

Digital camera body type: card, consumer/home/telephoto, SLR, paraxial. 1. Card digital cameras refer to those digital cameras with slim body and ultra-thin fashion design. Disadvantages: the manual function is weak, the large LCD screen consumes a lot of power and the lens performance is poor. 2. Consumer digital cameras, which are often called "fool cameras", can't change lenses. CCD has small area, good at low sensitivity and high sensitivity time difference. Its image has been processed according to people's appreciation habits in the process of preservation, so some details are lost, which is not conducive to reprocessing, but it can meet the needs of ordinary families. Household cameras are aimed at ordinary household users, who use cameras mainly to record their daily lives and are generally sensitive to price requirements. In addition, they are required to be as simple and easy to use as possible, and the requirements for the appearance and image quality of the camera are not very high, which is the main feature of household cameras. 3. The telephoto digital camera is also a consumer camera. Its main feature is that it has a long zoom distance and can shoot a farther scene. However, due to the poor quality of the lens and the small photosensitive element, the quality of its telephoto end is often not good enough. However, due to its rich manual kinetic energy and certain autonomy, it is mainly suitable for some beginners to master photography knowledge. 4. SLR digital camera, also known as single-lens reflex digital camera, has a viewfinder in the middle, and the incident light of the lens can be reflected by a pentaprism, which can achieve a "what you see is what you get" close to the real effect, and the lens can be changed. At present, SLR digital cameras are located in the high-end products of digital cameras, so the area of photosensitive elements (CCD or CMOS) related to the photographic quality of digital cameras is much larger than that of ordinary digital cameras, which makes the photosensitive area of each pixel of SLR digital cameras much larger than that of ordinary digital cameras, so each pixel can show more detailed brightness and color range, which makes the photographic quality of SLR digital cameras significantly higher than that of ordinary digital cameras. Compared with consumer digital cameras, they are "unsightly" and generally need post-processing, which is suitable for professional creators. Most consumer digital SLR's are made of engineering plastics, and their service life can't be compared with professional SLR's, and the shutter times of consumer digital SLR's are mostly short.

Professional equipment mostly has the following commonalities:

1 It can still work stably in extremely harsh shooting environment;

2) Functional design is closer to people's operating habits;

3) Quick and accurate response;

4. High quality color reproduction. 5. The paraxial digital camera is observed from one side of the camera. Generally, there is a manual wrench on the right side of the camera, which is connected with the winding shaft. The paraxial lens with replaceable lens is a lens with different aperture and focal length according to its own bayonet. Paraxial digital cameras are not what you see is what you get. But paraxial cameras also have many advantages. First, the paraxial camera doesn't have a reflector cabin like a SLR camera, that is, its lens can be close to the film or photosensitive device, which is very beneficial to imaging. Therefore, it is generally believed that the wide-angle lens of the paraxial camera is better than that of the SLR camera (but the telephoto lens, in turn, is difficult to focus because of the different paraxial cameras). When shooting without a mirror, the vibration of the machine is small. Compared with SLR paraxial camera, paraxial camera can shoot a clear picture at a lower shutter speed. Paraxial cameras can be made very small. Compared with SLR, paraxial camera can make people relax when shooting. SLR is aggressive, so paraxial camera is more suitable for humanistic photography. Relatively speaking, it is simpler and more reliable than a SLR camera.

What kind of digital cameras do you have?

Lead: At that time, digital camera was still a very small project for Kodak. Because of the decision to adopt digital mode, there are not many mobile machines in the camera. Cezanne and two technical engineers completed the project. What kind of digital cameras do you have? Welcome everyone to refer to it!

What kind of digital cameras do you have?

Digital cameras mainly have the following types:

Digital SLR: Like film SLR, single-lens imaging is professional, with high pixels, rich manual functions and high imaging quality (representative: Canon 20D).

Digital telephoto: usually the optical zoom is 8 ~ 12 times, and the manual function is rich. Compared with the higher cost of digital SLR lens, digital telephoto is more convenient and affordable. Telephoto is suitable for taking portraits and places where you need to look far (representative: Panasonic Z30).

Telephoto camera: it has multiple optical zoom and certain manual function, which is suitable for creative use;

Micro single camera: interchangeable lens, light SLR quality card.

Fashion camera: stylish and light (card machine), easy to carry, clumsy to operate and expensive (representative: Sony T9).

Entry-level camera: low price, rich functions and easy to carry. Optical zoom is generally 3 ~ 5 times, and some are wide-angle (such as Ricoh CaplioR3), with pixels between 3 million and 7 million. They can be operated by a fool or manually, which is suitable for different needs of users. In short, the price is cheap and the quantity is sufficient (for Canon A6 10).

Card camera: portable and low in price, basically meeting daily needs;

SLR camera: excellent imaging, interchangeable lens, professional first choice;

What are the meanings and functions of various parameters of digital cameras?

Digital cameras have many parameters. Let's take Canon G7X as an example to explain it in detail.

SD card; SDHC card; SDXC card _ _

This is easy to understand, that is, the supported memory card types.

There is no _ _ in the fuselage memory.

That is to say, do you have memory space? No, that means you must install a memory card to take pictures.

Other interface USB2.0 high speed, HDMI output _ _ _

These are some interfaces that come with the camera. It should be noted that USB2.0 interface is not a common interface, and cables should be saved. HDMI is an output interface, which can output video and audio.

NFC

This main function is used for wireless transmission. At present, the main function is wireless transmission to mobile phones.

WiFi connection

This is easy to understand. Everyone uses it every day. You can directly connect to the wireless network and upload it to places like friends circle and network disk, which is more convenient to use.

Fuselage flash

Used to fill the light for taking photos and increase the brightness of photos in the case of insufficient light. Generally, it is not recommended, and the effect of direct use will not be too good.

Battery-type rechargeable lithium ion battery

Most digital cameras use lithium-ion batteries. Remember to take out the battery when not in use, which will be safer.

The battery life is about 500 or less.

In other words, how many photos can I take on a single charge? Generally, the number of the manufacturer's target can't be photographed. Take 500 pictures, and actually take 400 pictures.

Sensor CMOS

A kind of sensor, the sensor on the general mobile phone is also CMOS.

Optical zoom factor 4-5 times

The zoom mode realized by the lens can be understood as zooming in and out of the scene.

Effective pixels above 1600

This is easy to understand, that is to say, the size of the photo taken.

Sensor size 1 inch

This is the size of the sensor. Theoretically, the larger the sensor size, the better the photo quality.

ISO automatic sensitivity, ISO 125-ISO 12800.

Sensitivity can be understood as the amount of light entering. Simply put, it is the size of the window. The bigger the window, the better the lighting, but not the greater the sensitivity. If the sensitivity is too high, the photo will be overexposed and appear white, which needs to be decided according to the shooting scene and shutter speed.
