1 How to choose a digital camera?

Many consumers, because they don't understand digital cameras, unilaterally think that pixels are high. Not exactly. When choosing a digital camera, we should consider its digital and optical characteristics.

1, digital camera lens. A well-designed high-end camera lens consists of multiple groups of lenses, including aspherical lenses, which can significantly reduce color shift and minimize graphic distortion and distortion. Expensive fluorite or glass is used as a lens. In order to reduce weight and cost, the lenses of household and semi-professional cameras are made of resin.

2. Image value of CCD of digital camera. CCD is the heart of digital camera, and it is also one of the main factors that affect the manufacturing cost of digital camera. Therefore, it has become an important standard for digital camera classification. At present, the entry-level product is 130-265438+ million pixels, while commercial and semi-professional users prefer products with more than 3 million pixels.

3. Zoom of digital camera. Optical zoom 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.

4. Battery and power consumption of digital camera. Digital cameras have LCD screens and built-in flashlights, so the battery consumption is higher than that of traditional cameras. It's cheap to use the No.5 battery, and you can buy it anytime and anywhere, but it won't take long for the battery to die. Therefore, it is best to choose the model equipped with rechargeable lithium battery. At present, mainstream digital products have been designed as lithium batteries, and complete charging equipment is provided as accessories.

5. Additional functions. The more functions, the more fun and uses it means to use a digital camera. For example, many digital cameras have video output function, which can be connected to TV to browse photos; Some can set their own startup screen and shutter sound like mobile phones; Some can have short-term digital video recording function. The driver installation of digital camera should be very simple, and it should be able to download pictures quickly and preview them. For example, the software function attached to Canon digital camera is perfect, which can classify and manage pictures, and the settings when printing are more diverse, and pictures can also be simply modified.

Kejia camera service station is a professional maintenance station for Japanese Canon cameras, Olympus cameras and Pentax cameras. It can repair not only traditional cameras but also digital cameras. At the same time, there are various digital camera batteries, covers, memory cards and card readers for sale, which can meet your various needs of using digital cameras.

2. How to choose a digital camera: Pixels are not the most important.

Digital cameras have only entered the field of vision of ordinary consumers for two or three years, but their technology is developing as fast as other IT products, so that some people put forward Moore's Law of digital cameras: every 18 months, the technical level of digital cameras doubles, while the price is halved. In fact, this rule seems a bit conservative. I don't know 1999. The newly released 2-megapixel digital camera was replaced by 3-megapixel digital camera in early 2000.

How to find a good product that is "easy to use, sufficient and practical" in such a rapid technological innovation? Pixels are not the only thing that matters. Understanding our actual needs is the primary problem that our consumers should consider when buying digital cameras.

Early digital cameras were all below/kloc-0.0 million pixels. Since the second half of 1999, 2-megapixel products have gradually become the mainstream of the market. Pixel refers to the resolution of a digital camera, which is determined by the number of photosensitive elements on the photoelectric sensor in the camera, and one photosensitive element corresponds to one pixel. Therefore, the larger the pixel, the more photosensitive elements, and the greater the corresponding cost. The image quality of a digital camera is determined by pixels. The larger the pixel, the greater the resolution of the photo, the larger the print size and the larger the memory capacity without degrading the print quality.

At present, the development trend of digital cameras is that pixels, like the CPU frequency of a PC, have a growing momentum. Many consumers, like the original PC users, take the pursuit of high pixels as their ultimate goal.

In fact, from the perspective of market classification, for popular products, considering the factor of cost performance, the bigger the pixel, the better. After all, 800-/kloc-0.00 million pixel products can meet most applications of ordinary consumers. Therefore, while most manufacturers are pursuing high-end digital cameras with high pixels, the largest output at present is still the popular mega-pixel products. According to BCN's digital camera market survey, the market share of low-priced digital cameras was only 5.6% in mid-April, and reached16%-17% in early May:19. From June to June 26th, the market share of digital cameras below 10,000 yuan reached 24.5%.

Facts have proved that the same is true: Recently, Samsung Digital launched a digital camera-SDC-80, which is very popular among young netizens. Its "gorgeous shell and excellent cost performance" have made its sales performance climb all the way. Xu Hang of Samsung Electronics Digital Department said that at present, low-priced digital cameras are refreshing and attractive in the international market, which coincides with our goal of providing consumers with high-quality and low-priced products: first, as long as they are fun and easy to use, they would rather sacrifice unnecessary functions of the products; Secondly, although the definition of low-pixel digital camera is low, it is enough for individual users and e-mail transmission, and it is much more troublesome to process high-definition pictures; Thirdly, according to authoritative sources, digital camera products will develop in two aspects: professionalism and popularization, and popularization will be valued by more and more consumers.

3 "Tip: How to choose a digital camera?"

With the development of the digital age, more and more people face computers with graphics and images, and digital cameras, as a digital input device, have gradually begun to be favored by ordinary family users. Then, as an ordinary user, it is very important to choose a good digital camera to help him with his office work, document management, Internet entertainment and even professional production. The following are some points you should consider when choosing a digital camera.

functional principle

The resolution of the camera determines the ability to express details in the captured images. The higher the resolution, the higher the price of digital cameras. Is there a digital camera with high image resolution and excellent performance? Some smart manufacturers combine the characteristics of digital cameras with software to improve image resolution and image quality. Among them, the most famous software is PNOTO Genie, which is a unique artificial intelligence technology, which avoids the phenomenon of high contrast tone, missing corners and pixelation of images. After the image resolution is improved, the image effect is greatly improved compared with the original camera resolution. The image resolution achieved by using this technology is similar to that achieved by hardware. In contrast, this kind of digital camera is cheaper. Sanyo 400 is the leader and leader in adopting this technology.

economic principle

Most digital cameras have color LCD screens. Through the LCD screen, you can preview and delete any image at any time, which brings a lot of benefits and convenience, but it also brings inconvenience, because it is a rather power-consuming device. Generally, four batteries can only image about 15, and then there is no electricity (turn on the liquid crystal or use the liquid crystal to see the effect after shooting), so there is a revolutionary technology, that is, the application of lighting energy-saving LCD screen. By collecting external light source, the LCD of digital camera can display images, which greatly increases the service life of the battery and saves consumers' expenses. According to industry speculation, this technology will basically be used in digital cameras in the future, and the digital cameras that use this technology now include Sanyo 400.

Functional enrichment principle

Zoom: The wider the zoom range, the wider the camera, and zoom is directly proportional to the price of digital camera.

White balance (human eye function) function: Simply put, the human eye will adjust the color sensitivity according to the different climate or lighting conditions, so that white objects always appear white. The white balance correction function is to make the camera have the same function as the human eye, and automatically adjust the internal color balance by calculating the average value under different lighting conditions, so as to achieve the effect of truly reproducing white under all conditions.

Exposure compensation: A digital camera with exposure compensation can change the brightness of a photo.

Close-range distance: The closer the close-range distance is, the more clearly you can see tiny words or patterns.

To sum up, I believe it is easy to choose a suitable digital camera.

4 "How to choose digital cameras and accessories?"

1. first analyze your own needs, that is, what do you mainly want to shoot, people or scenery?

If it is wide-angle, it is better to be 28 mm. Consumer-grade dc seems to have only D7 and D7i for the time being, and other cameras have to add 1xxx to buy wide-angle lenses.

Sony707, Nikon 995, 2500 and New 4500 are the most famous people who like to take candid photos. Because it is a rotating lens, the candid photos are good. Fuji 30i, 40i and 50i all look like mp3 players, so probably no one will pay attention to taking pictures.

Close-ups like Olympus 700, 720 (with slightly stronger purple edges), Casio 2900, Canon pro90, Olympus 2 100 and Nikon 5700 are all telephoto, which means you can shoot distant targets.

2. Individual level differences

I can already shoot, but I used to play with a SLR. Generally, this kind of camera will not be satisfied with a low-grade digital camera unless I buy one as a toy. In this case, if you used to use Canon dc, some accessories can still be used. Whether Nikon is universal or not, I dare not talk nonsense, because I am not familiar with it.

I don't know how to shoot, but I want to learn photography. Just like me, I used a poor stupid machine at first, and sometimes a roll of film can only print 1x copies, which is expensive. With a digital camera, this problem is solved. I think such a person must buy a camera with aperture shutter priority.

I don't know how to shoot, and I don't want to learn photography. It is enough to buy a fully automatic camera without aperture shutter priority, which is enough to replace the optical automatic camera at home. Sure, buy a better one. There are many cameras of this grade, and they also produce the most new machines.

The concept of 3.3. Total cost of ownership:

How much are you going to spend on cameras and accessories? The cost of using a digital camera is lower than that of using film. A roll of ordinary film print photos is almost 1 yuan/sheet. This question is not discussed for the time being.

Digital cameras need batteries, some are special lithium batteries, which are more expensive, and some are No.5 batteries. The rechargeable No.5 batteries are much cheaper. Some netizens made their own batteries, which are very easy to use. Of course, they should also be risk-conscious.

There are also storage media, such as Panasonic's SD and Sony's MemoryStick, which are more expensive, while SM's maximum capacity can only reach 128M, cf I &；; II has the largest 1G, and IBM's microdisk, and now it has1g.

There is also a UV mirror to protect the lens. Try not to touch the lens, so use a UV mirror. Generally speaking, domestic products such as nature and seagulls are barely enough. Hoya and Kengo can be considered for higher requirements, and German B+W can be considered for higher requirements.

Some cameras have telescopic lenses, so you may need to use an adapter ring. Then buy a rubber hair dryer and brush to blow away the floating dust. Never blow with your mouth, it's easy to get moldy.

Tripods or monopods are also important. Of course, generally we don't need such a high-end tripod, but generally speaking, the heavier one is better than the lighter one, and the fewer joints, the better. Workmanship is very important, which is related to stability. Generally speaking, the low-grade Mo Lifeng is OK (I didn't get a kickback), but the requirements are high, but the money is not too much. You can consider Mantu in Italy and Admiralty in Japan. For those who want to burn friends regardless of quality, you can buy Gitzo in France. In the past, people used to build gun supports, so building tripods is not just for fun, it is definitely not moving.

The first choice of cost performance! Take a comprehensive inventory of the recent 2500 yuan digital camera market (1)

This paper will make a detailed and in-depth discussion on the seller's market and models of domestic digital cameras at present, which is about 2500 yuan, and provide reference for everyone to buy machines in summer vacation. Due to regional differences, the prices of related models are for reference only.

The domestic practical digital camera market has always been the main gathering place for digital camera manufacturers. Sony P series, W series, Canon IXUS series, A series, Fuji F series, E series, Nikon Coolpix series, Kodak DX series, LS series, Olympus μ series and Panasonic FX series all gather here, and the fierce competition can be imagined. In this market field, the digital camera market of about 2,500 yuan is a battleground for all military strategists!

Why is the digital camera market with a price of 2500 yuan a battleground for military strategists? First of all, judging from the current level of social development in China, life in many places has reached or even exceeded the well-off level, and the psychological price of high-end consumer goods is mostly concentrated in 2000 yuan to 3000 yuan; In addition, judging from the current development level of the digital camera market, the model with the price of 2500 yuan is not only more comprehensive in function, but also full of flowers in design, and the trend of fashion and personalization is extremely obvious, which undoubtedly attracts the attention of many consumers. In fact, from the current development of digital camera technology and market situation, the consumption of digital cameras at the price of 2500 yuan is still relatively rational. Too low, the appearance function is greatly reduced; It's too high. The fancy configuration is too high.

So, what kind of digital camera can you buy with 2500 yuan in your arms? As far as the current digital camera market is concerned, this price concentrates on three models with different time to market. Due to market and technical factors, the functional design or market conditions of these four models are slightly different. And according to the classification of time to market, we can also roughly see the future "market fate" of these models. These three types of digital cameras are: the latest model, the upcoming model and the upcoming model.

For choosing a suitable digital camera, our view is: there is no best, only the most suitable! I believe that in the hearts of many consumers, this shopping concept will always accompany you. Therefore, the author collected more than 20 kinds of digital cameras with a price of about 2,500 yuan for everyone to choose from. In addition to introducing their basic functions, I also added its recent market situation and comparison with similar models, hoping to provide some reference models for consumers who are about to buy.

Newcomers have great potential for laughter, and the new shopping guide is listed.

Since May Day, there have been many new figures in the digital camera market, many of which are practical household digital cameras with a price of 2,500 yuan. Most of these models adopt innovative technologies or hardware configurations, such as Pentax underwater photography, Kodak digital red-eye prevention, Samsung safety flash mode, 50MB large-capacity built-in storage, etc., which are very practical. Moreover, these latest models have great potential for price decline, which deserves our attention.

1. New concept of Pentax underwater photography

Pentax, a traditional optical manufacturer, has not made great achievements in the digital camera market, but it has frequently used troops recently, and its various card-type digital cameras have recently been listed one after another. The most noteworthy is the latest underwater photography model OptioWP, which is light in shape and only 22mm thick. It is a fashionable card with exquisite workmanship. The most surprising thing is that it has 8 waterproof functions and can shoot normally for 30 minutes at a depth of 1.5 meters underwater. In terms of hardware configuration, it adopts a 5-megapixel CCD, a 3x optical zoom lens and a 2.0-inch LCD screen, which is a standard home computer configuration.

The starting price of this model is as high as 3200 yuan, which has no obvious advantage over other cards in terms of price and performance. Surprisingly, this model went on sale in fall in price soon, and now the price is only 2699 yuan. Compared with other 5 megapixel cards, its price advantage is very obvious, and it also has the special function of underwater photography. For friends who often shoot in swimming in hot summer, it is wise to buy OptioWP.

Although OptioWP has just been listed, the user's evaluation of this model is still quite high. I believe this has a lot to do with its underwater photography and thin fuselage design.

Pentax S5Z and S55 were also listed in the same period. The former costs more than 3000 yuan, so I won't describe it here, but the latter deserves your attention. Pentax S55 is a high-end digital camera for home use, which is both practical and fashionable. It uses a 5-megapixel CCD, a 3x optical zoom SMC lens and a 2.5-inch LCD screen. Compared with the above-mentioned OptioWP, S5Z and S55, this model has fewer functions and a relatively large thickness.

However, after more than half a month on the market, the price of this model dropped sharply in 200 yuan, and now the quotation is only about 2280 yuan. Among the 5 megapixel large-screen digital cameras, S55 has a high cost performance! Pentax S55 is a good choice for consumers with a tight budget of 2500 yuan. Moreover, it uses SD card and AA battery, so the later purchase cost is lower and the battery is more universal. The disadvantage of this model is that it has few functions, and the highest resolution of animation shooting is only 320x240.

How to choose a digital camera

Digital camera is an electronic product, which can shoot and convert the shot images into digital signals through CCD (Charge Coupled Device) and internal processing, and store them in the camera memory or external memory in the form of digital image files.

The advantages of digital camera are: (1) no need for film and printing of traditional camera; (2) fast imaging speed, that is, it can be displayed immediately after shooting, and dissatisfied photos can be deleted and retaken at any time; (3) Using image processing software, you can edit pictures at will and get special effects; (4) Instant transmission of images through multimedia technology and Internet.

Pay attention to the following points when buying digital cameras:

First, buy from reputable merchants and keep the invoices.

Second, choose a camera that is cost-effective and suitable for your needs. When digital cameras bought by ordinary consumers are mostly used in daily life and travel, 2-3 million pixel digital cameras are enough to meet the needs. Therefore, there is no need to deliberately pursue a digital camera with the most functions and the highest pixels. This kind of camera is more expensive. The higher the pixels, the fewer photos you take.

Third, choose and buy batteries, chargers and memory cards that are allowed to be used in the product manual.

When buying a digital camera, you should consider whether it matches a personal computer, including the processing power of CPU, the memory size and the quality of the monitor. The quality of image processing will also affect the final imaging quality.

The use and maintenance of digital cameras;

First, after buying a digital camera, first read the product manual carefully, especially pay attention to the "warning" clause.

Second, it is very power-consuming to use LCD to observe images when shooting. It is recommended to turn off LCD immediately after taking pictures. Avoid heavy pressure during storage.

Third, digital cameras should be stored in a dry environment. If you don't use it for a long time, you should take out the battery.

4. CCD chip of digital camera is very sensitive to strong magnetic field and electric field, so it should be paid attention to when using and storing. Do not put it near TV sets, stereos, induction cookers and other equipment.

First, choose the machine that suits you.

There are only three kinds of people who buy consumer digital cameras: 1, here is a tour. This demand is usually recorded with a video camera.

Recording life, the performance of the camera, imaging quality requirements are not very high, generally buy some beautiful appearance, small and light, more expensive.

Cheap camera. For example: 99+ 1 series, Canon V series, Sony P series, Olympus U series, Nikon 2 series, Fuji a203, f40 1 and other machines are more suitable. If the budget is not much, you can consider domestic machines below 1000 yuan;

2. People who record their own lives and have some interest in photography. The needs of these users, in addition to meeting the above conditions, also need camera support D.
