Buy a digital camera, experts come in.

Personal recommendation: Sony, its ccd technology is made by itself, and it also has the function of memory stick.

Sony is a very special brand in digital photography. T series is an ultra-thin portable card model with periscope lens, and this series is most popular with MM, H is telephoto series, W is high-end practical consumer household model, and R series is Sony professional high-end digital camera series; P series is a low-end household model; S series is a low-end practical model with low price; U series is an ultra-small fashion model; F series is a high-end model with a rotatable lens. F7 17 in the F series was once famous and became a classic model.

Advantages and disadvantages

Sony's achilles heel is its weak optical foundation and lack of its own lens. Most of its models use the OEM lens of German Carl Chase, which has become the main material for people in the industry to laugh at Sony. But Sony also has its own advantages, strong electronic technology, providing CCD sensors for many camera manufacturers; In addition, Sony focuses on the consumer camera market, and its products are rich and fashionable, which are deeply loved by fashionable young people.

Advantages: beautiful appearance, good fashion advertising and good brand of Sony consumer electronics products. Disadvantages: high price, expensive accessories and maintenance, monopoly (using special memory chips), not as good as Canon.

Pay attention to when buying digital cameras:

Key points of digital camera purchase

With the progress of society and the accelerated pace of life, people are thinking about enjoying life while creating wealth. Everyone wants to keep their beautiful moments. Digital camera is no longer the choice of a few "optimizers", it has entered the civilian consumers. We can pay attention to the following aspects when choosing a digital camera.

Key points of purchasing main components of digital camera

Charge coupled device

As a key component of digital camera imaging, it affects the quality of photos taken and the manufacturing cost of the camera, so the value of CCD becomes an important standard to determine the grade of digital camera. The quality of photos is largely determined by CCD pixels. The more CCD pixels, the more accurate the captured image, so generally speaking, the higher the pixels, the better the imaging quality. At present, the CCD pixels of digital cameras are generally in the tens of thousands, such as 5 million pixels and 7 million pixels, 8 million, 6.5438+million and of course higher. Generally speaking, the higher the pixel, the higher the cost. At present, the mainstream is 7,008,000,000 pixels, but for ordinary families, 5,000,000 pixels is enough. It is wise to choose according to your own needs.

camera lens

The lens can be said to be the eye of the camera, and it is the only path for external light to enter the camera for imaging, so the quality of the lens also affects the quality of imaging, which must be paid attention to when purchasing a camera. Three key points that determine the quality of a lens: transparency, distortion of light and zoom ability. The first two are difficult for ordinary people to judge, but I believe many people have heard of zoom ability, which is very important for you to shoot distant objects. The better the zoom ability, the farther you can shoot the object. The zoom ability mentioned here refers to optical zoom without losing image clarity. At present, the zoom is usually 3 times, and the high zoom is 12 times or even higher.

Digital camera battery

The battery durability of digital cameras can not be ignored. Among cameras, LCD screen and flash are the most power-consuming, and the batteries used in digital cameras are mainly lithium batteries and general dry batteries.

Lithium batteries are characterized by small size, portability, high cost and low versatility, while dry batteries are characterized by low cost, high versatility and large volume. When you can buy a low-power camera, you should prepare a spare battery when you go out to take pictures.

The capacity and performance of AA rechargeable battery have been greatly improved. After 2003, AA Ni-MH batteries with more than 2000 mA came out continuously, and high-performance batteries with fast charge of 1 hour and fast charge of half an hour appeared. The performance is directly comparable to that of lithium battery, and the use cost is low. However, lithium batteries often cost several hundred yuan, so AA batteries are relatively more cost-effective.

hum

The optical zoom of digital camera is a real zoom, which will not affect the imaging quality of photos; Digital zoom is electronic zoom, which is a local enlargement at the expense of photo clarity. The larger the optical zoom factor, the farther the shooting distance can be. Digital zoom is equivalent to cutting photos on a computer. Some people say that optical zoom × digital zoom can get dozens of times zoom. For example, the nominal 50x zoom is actually the result of 10x optical zoom× 5x digital zoom.

Storage format

Many different data storage device formats are used in the consumer digital camera market:

CF card (compact flash memory)

SM card (smart media)

MMC card (multimedia card)

SD card (secure digital card)

memory stick

Xd picture card

Key points of whole machine procurement

Price–performance ratio

The most important thing is cost performance. Different types of cameras have different styles and characteristics. We need to consider what kind of camera to buy as a whole.

Home users only need to shoot with good quality, simple function and low price.

Ordinary families don't have to spend too much on digital cameras. The price of 2000 -3000 yuan is psychologically affordable. It is good that the function is simple and the operation is convenient.

Ease of use is also important Many domestic digital cameras have been humanized in key design, menu system and white balance adjustment. The functional design is intuitive and the operation is quite simple. Even some manual options are quite simple. You can understand them by reading the manual.

If you still feel trouble, you can use the preset scenes such as portrait, automatic P file and night in the menu. These scenes have all the functions needed to shoot a specific environment, and users can finish shooting by pressing the shoot button.

after service

After-sales service is an essential part of buying any product. Digital cameras are expensive, and good after-sales service is psychological guarantee. Well-known brands not only have first-class products, but also first-class services, so try to buy products from well-known brands, ask about the regulations of after-sales service, and keep the warranty card well to avoid unnecessary troubles that may occur in the future.

Be sure to get the invoice.

Not invoicing can save some expenses (about 5% of the total price), and businesses also avoid taxes. On the surface, both are beneficial. Actually, it is not. No invoice will affect the warranty and consumers will suffer.

For example, Canon clearly stipulates: "Please show the warranty card and purchase invoice when requesting maintenance. Canon's authorized maintenance organization has the right to refuse the warranty without showing a valid warranty card and purchase invoice. According to the understanding of Canon Treaty, the warranty card and purchase invoice can be presented at the same time before maintenance can be given. Moreover, the cost of core components far exceeds the 5% cost savings.

For example, suppose that the total price of the camera is 3,000 yuan, which is cheaper without invoicing 150 yuan, and the replacement of CCD is less than several hundred.

Misunderstanding of digital camera purchase

The higher the pixel, the better.

The pixels of digital cameras range from 5 million to10 million, and some high-end cameras even exceed10 million pixels. Consumers are very concerned about the pixels of digital cameras when buying cameras. I think the higher the pixel, the better, but it's not. Pixel can't be the only criterion for choosing a digital camera. How big is the pixel? Enough is good!

Nice lens and camera.

The function and quality of the lens greatly affect the imaging quality of the camera. When purchasing a digital camera, we should pay attention to the brand of the lens, the size of the focal length and the zoom ability. A good digital camera lens is composed of multiple groups of lenses, and the lens material is optical glass or other special materials. High-quality lenses include ground aspheric lenses and low dispersion lenses. Aspheric lens is used to suppress the distortion of the shot picture, while ed lens is used to reduce the dispersion.

Is the bigger the zoom, the better?

Zoom multiple is the focus of consumers' general concern. Is it better to zoom as much as possible? It is impossible to know the shooting situation of a digital camera simply by looking at the size.

A larger zoom factor can make a digital camera more flexible, but it is not easy to know the shooting situation of a digital camera just by looking at the size. First of all, pay special attention to the range of optical zoom. The smaller the minimum focal length of the camera, the larger the wide-angle shooting range, which is beneficial to shooting large scenes, while the larger the maximum focal length, the stronger the telephoto ability. Let's take a lens with 3 times optical zoom as an example. Its focal length ranges are 28mm~85mm and 35 mm ~105 mm. When traveling, the lens with 35 mm ~15 mm is weak when dealing with large scenes, while the lens with 28 mm ~ 85 mm is more valuable.

Digital cameras also provide digital zoom function.

Compared with traditional cameras, digital cameras also provide digital zoom function, which is very different from optical zoom. Digital zoom is to enlarge the shot photos, interpolate by calculation, and fill in the blank scientifically, so as to achieve the visual zoom effect. It should be noted that the more interpolation components, the more details of the sacrificed picture, and the lower the definition. There is no practical significance for taking pictures themselves.

Other influencing factors

CCD size CCD size actually refers to the area of the photoreceptor. The larger the CCD/CMOS area, the more photons are captured, the better the photosensitive performance and the lower the signal-to-noise ratio. In other words, the imaging of11.8 inch camera is better than that of 1/2.5 inch camera. At present, most models on the market are 1/2.5 inches, but a few models are11.8 inches, which is definitely worth recommending.

Focusing speed is related to the success of snapshot, which is more important when the light is not ideal.

Scene mode Some low-end digital cameras don't have manual gears, so scene mode is essential. It can ensure the shooting quality of novices in different scenes, for example, taking pictures at night requires night scene mode.

White balance mode The richer the white balance mode is, the more accurate the color reproduction will be in various environments, such as cloudy days and sunny days.

ISO in low light is to improve ISO to take bright photos, but the higher the setting, the more obvious the noise will be. The mainstream ISO in the market is 100~800, but some cameras provide a higher ISO setting of 1600, which is of little practical value.

Macro-The closer the macro shooting distance is, the smaller the pattern can be seen, which is suitable for users who like shooting details.

What problems should I pay attention to when buying an online shop?

Choose a store]

Choose a good shop, choose a professional camera shop and brand shop;

See if the goods he sells continue to deal in similar goods.

See if the owner agrees to meet in the same city and agree to pay Alipay in different places. If the shopkeeper can only mail order, can't meet each other and can't use Alipay, he should give up without hesitation, even if there is an attractive price.

Try to choose a store with a higher reputation, preferably one with a reputation higher than that of diamonds, and look at its transaction records. If its reputation is accumulated by selling cards, online games and other virtual products with lower prices, it will be carefully considered.

Selection step

Choosing a digital camera must follow the following steps: Decide your own budget-> Choose camera parameters according to your own budget-> Select the models of several brands according to the parameters-> After delineating the intended model, go to the big digital website to see the evaluation-> Decide on a certain model-> Communicate directly with the owner to discuss details such as price configuration warranty-> When purchasing, it is more important to pay attention to the product quality and after-sales service while comparing the prices.

Buy a digital camera within your power.

Before buying a digital camera, you should take your own economic strength as the premise and do what you can. Unless you are a professional photographer, you just need to buy a camera that can meet the needs of your home. 1500-3000 cameras can meet your daily shooting needs. In addition, we should also consider the development of technology, the length of the elimination period and other factors, and choose the right model according to the current shooting level. Budget is still its core role and should be considered first.

Communicate with the owner

Some buyers think that talking about details is bargaining, but it is not. It's not your goal to chop 50 yuan for 2000 yuan, but your ultimate goal is to buy goods with cheap price, excellent quality and after-sales guarantee. Therefore, the final communication with the owner should be to carefully ask whether the picture is consistent with the real thing, whether the real thing is consistent with the description, what accessories to visit, how to ensure after-sales, how to repair after the warranty period and so on. These important questions have been satisfactorily answered and promised, and you can ask for price reduction or gift as appropriate. Because there are few machines that renovate digital cameras, they rarely replace the internal parts of brand-new machines, but some businesses may replace accessories, especially batteries, in order to make huge profits. An original digital camera battery costs about 300 yuan, while a domestic high imitation battery costs only tens of yuan, which is one of the reasons why their price tag is lower than that of other manufacturers. You need to ask before buying.

Transaction purchase

When you decide to buy and shoot a digital camera after comparing the price, product quality and service, both buyers should contact quickly to reach a deal. As a seller, it is obliged to describe the goods truthfully and provide the promised after-sales service; As a buyer, we should also pay in full and on time, which is the support for honest shopkeepers.

What problems should be paid attention to when purchasing retail websites?

Determine the main purpose of the camera and the type, style and price of the camera.

Don't rush for success, buy it immediately, and make a comprehensive comparative analysis of multiple websites to get benefits.

If you don't know much about digital cameras, you can also go to the relevant digital camera forum to participate in the discussion and listen to the opinions of netizens.

When all doubts are eliminated, you can place an order with confidence.

Please note the following points when placing an order:

Confirm that the harvest address and contact information are correct.

It is recommended to choose cash on delivery, and you can choose not to guarantee that the product is inconsistent with the website introduction when receiving the goods.

After-sales service, warranty card confirmation, remember to invoice.

Waiting for a receipt

Problems that should be paid attention to when buying in promotional activities

Don't change the original purchase plan easily.

After entering the store, the overwhelming promotional posters, under the strong persuasion of promotional MM, must stick to it and try to inspect the target camera according to the original purchase plan. Because the target camera must have been carefully investigated and selected, you are familiar with its advantages and disadvantages. If you temporarily change your purchase plan in the store, you will probably only see the advantages of some cameras and hardly notice their disadvantages. So the initial choice seems to be more reliable than the temporary purchase decision made in the store.

Don't be blindfolded by gifts.

Whether it is manufacturers or businesses, various gifts will be launched during the National Day to stimulate sales. At this time, please don't be blinded by these gifts.

For those gifts that are not helpful for shooting, such as water cups, toys, commemorative watches, satchels, etc. It really doesn't mean much. Why because they spend more money?

Some gifts were originally provided by manufacturers for free, and it would be even more unkind if merchants used this to raise the price of cameras. For example, many Samsung cameras have two original lithium batteries when they leave the factory, but some merchants sell them at high prices or deduct one of them at low prices. Please be on high alert.

Pay attention to verify the true value of the camera itself.

Even in the face of those expensive gifts, such as memory cards, batteries, camera bags, LCD protective films, card readers and so on. , but also pay attention to weigh the real value of the gift, and then get the actual stand-alone price of the camera, don't waste money because of bundling. Generally speaking, the market price of gifts is roughly as follows.

SD card (60x speed): 1G(40 yuan), 2G(70 yuan), 4G( 120 yuan).

Memory module: 5 12M (100 yuan), 1G( 150 yuan), 2G(200 yuan).

XD cards: 5 12M (120 yuan), 1G( 180 yuan), 2G(250 yuan).

Lithium battery: the original battery is about 200 yuan, and the non-original battery is about 100 yuan.

AA rechargeable battery: 4 packs of 2300mA charging sets are around 60 yuan, and 4 packs of 2300mA fast charging sets are around 90 yuan.

Liquid crystal protective film: about 10 yuan.

Camera bag: Card camera bag is about 20 yuan, and slightly larger camera bag is about 30 yuan.

Card reader:1around 0 yuan.

Don't be misled by the information of "out of stock"

"This camera sells well and the supply has been insufficient. If you don't buy it now, you may not be able to buy it later. " If you hear such persuasion, there is absolutely no need to be flustered. As long as it is not a very popular camera, the problem of shortage will basically not exist.
