What are the mainstream brands of digital cameras? What configuration do you mainly look at when buying? What are the better models?

We can't simply say which brand is better, only which brand is better. Now digital cameras are still the world of Japanese goods. First-line brands include Canon, Sony, Fuji, Kodak, Nikon, Olympus, Pentax, Ricoh and so on. Second-tier brands include BenQ, Innovation, Epson, Kyocera, Panasonic, Samsung, Toshiba, Lenovo and Hewlett-Packard.

They are all good brands. There are also corresponding models. Don't just look at the brand, mainly look at the functions you need.

The first big misunderstanding: the higher the pixel, the better.

This is a question I often ask many netizens, and when I buy a digital camera, I also ask, "Do you think a 6-megapixel machine is much better than a 3-megapixel one?" "How about an 8-megapixel digital camera?" Wait a minute. It must be pointed out that this purchase misunderstanding is:

Buying on demand is the right way. With the principle of pursuing high pixels, it is not necessarily a good digital camera to buy.

Some digital camera advertisements claim that the resolution of this product is as high as 6 million pixels, but the price is relatively low, which is undoubtedly very attractive to ordinary consumers. A careful study of the specifications of this camera shows that the so-called resolution of 6 million pixels is only obtained by hardware interpolation, while the actual total pixels are only 3.3 million, and the effective output pixels without hardware interpolation are only about 3 million. This is most obvious in Fuji digital cameras and some domestic digital cameras. Fuji is ok, and the interpolated photos are acceptable. However, in order to cater to the tastes of some friends who don't understand digital cameras and only pursue high pixels, interpolation is also engaged. Because there is no core technology, the effect of interpolation is simply unacceptable.

At present, there are not many consumers in the market who can really distinguish between interpolated pixels, total pixels and effective pixels. Of course, consumers who often deal with digital cameras should be excluded. This mainly refers to consumers who want to buy digital cameras without in-depth research. Some digital camera manufacturers just take advantage of this weakness of consumers, touting how high the resolution of a camera is, and then inducing consumers to buy it.

The following are the correct buying principles:

Choose the largest non-interpolation pixel of your digital camera according to your needs!

From the practical application of consumers, most users take photos with digital cameras and then print them digitally. Now commonly used 2 million to 5 million pixels can meet daily needs. Among them, more than 2 million pixels is the most basic requirement for developing photos. 2 million pixels can reach the resolution of 1600× 1200 (this is the maximum resolution, and it is recommended to use 1280×960). According to the general standard of 300dpi, 265438+ 10,000 pixels can perfectly output 5-inch photos. At present, the 8 million market is very hot. According to this algorithm, photos larger than 16 inch can be output. But to be fair, can you use it? How much does it cost to develop a 14 inch photo! ? In addition, if it is displayed on the computer, the display of 19 inch will be displayed as 2048* 1536. You should also reduce the size of the photo. Don't say that you bought an 8-megapixel digital camera just to reduce the 8-megapixel photo to 3 million pixels. If so, 5 million pixels is enough.

The same price, but the pixel difference is 654.38+0 million. What do you choose?

By the first half of 2004, the effective pixels of popular models on the market were 3 million and 4 million respectively. Whether to pay the price difference for this 6.5438+0 million pixel is a matter of opinion, but considering that 4 million pixels is the mainstream direction of consumer digital cameras, the higher the shooting resolution, the greater the flexibility of shooting and saving images, so I tend to choose 4 million products. High-end models are usually products with 5 million to 8 million pixels, which are suitable for photographers. As for the SuperCCD used by Fuji, consumers should pay attention to the fact that its actual shooting effect can't have the same picture quality as the maximum output pixel (the output quality of 6 million is close to the 4 million pixel effect of the traditional CCD, so don't expect the interpolation effect to be compared with the real 6 million pixel digital camera! )。

The second biggest misunderstanding: there is no difference between CCD and CMOS photosensitive devices.

The price and imaging quality of CCD and CMOS photosensitive devices are very different.

At present, there are two kinds of photosensitive elements in digital cameras, one is CMOS, which has low manufacturing cost but poor imaging effect, and the other is CCD, which is more expensive than CMOS, but has better imaging effect at the same pixel value. (Consumer digital cameras do not discuss high-end CMOS photosensitive devices)

In addition, there are two kinds of CCD on the market at present. One is RGB primary color CCD, and the other is CYMG complementary color CCD. Both have their own advantages. If you only use the screen to look at photos, then the digital camera with primary color CCD should be better, because the general screen is represented by RGB mode. If users often need to output files as photos or engage in print output, it is more appropriate to use complementary color CCD. At present, most primary color CCDs use Sony Super HAD CCD and Fuji's exclusive Super CCD. Among them, Fuji's super CCD arranges the photosensitive elements on the CCD at an angle of 45, so it feels more on the pixels, but the actual pixels are not. Therefore, when buying Fuji digital cameras, we should pay attention to the pixels of the actual CCD, and don't be confused by the numbers.

For consumer digital cameras, I suggest consumers buy and use CCD photosensitive devices. The advantages of CCD in this field are very obvious.

At present, most digital cameras sold in the market use CCD produced by Sony, such as Sony, Canon and Olympus. Panasonic uses its own CCD. Most of Fuji's products also use self-produced super CCD. As far as home models are concerned, the individual differences of CCD are almost subtle, so there is no need to force them. Among these three parameters, consumers should mainly pay attention to the effective pixels of CCD.

The third misunderstanding: recognize the zoom function in the camera.

Digital cameras on the market now have two functions: optical zoom and digital zoom. The focal length reflects the distance of the scene that can be photographed. The zoom formula of digital camera is: zoom = optical zoom × digital zoom. Optical zoom is based on optical lens structure. The zoom mode is similar to that of a 35mm camera, that is, the scene to be shot is enlarged and reduced by the movement of the camera lens. The larger the optical zoom factor, the farther the scene can be shot (without losing the image quality). 3 million pixel digital camera is mainly based on 3 times optical zoom, and some are 2 times or 4 times. Digital zoom is to enlarge a part of the pixels on the original CCD sensor to the whole picture, so the amplification effect is not very "real". Some cameras are marked with high zoom, so buyers still need to know about optical zoom and digital zoom. Digital zoom has no practical significance, so it doesn't have to be too demanding. For example, Sony's F7 17 is 5x optical zoom * 2x digital zoom * * The total zoom is10x. But F7 17 only has 5 times optical zoom, and everything else is magnified by * processing chips!

With a digital camera with optical zoom function, we can shoot a magnified scene in the distance by adjusting the focal length, and we can have very clear photos. For today's digital cameras, CCD with the same resolution, if we compare zoom cameras with fixed focus (generally only digital zoom) cameras, they are also very different in price. For digital cameras with high pixels, it is generally necessary to have a zoom function of more than 3 times. If you often shoot some distant scenery or animals, you can also choose a digital camera with 6 times optical zoom function, so that the pictures you shoot will be more perfect.

Limited by the size of CCD, digital cameras usually use optical zoom lenses within 10 times, and some special products even use lenses with optical zoom ability around 12 times (at present, only Panasonic FZ 10 has optical zoom of 12 times), and the image quality will not be obviously affected after zooming.

It should be pointed out that many times manufacturers advertise that they have the zoom capabilities of "10x" and "14x" when selling, which is the so-called multiplication of optical zoom and digital zoom. Digital zoom has a great influence on the image quality, so we only need to take the optical zoom ability of the lens as the main reference index when purchasing.

At present, various brands of digital cameras also take the lens as their selling point, such as Sony's "Zeiss standard" lens, Panasonic's Leica lens, Canon's own Canon original lens, Nikon's own nikkor lens, Fuji's own Fuji Dragon lens and so on. The lens gap used by popular digital cameras is not obvious, but when purchasing quasi-professional digital cameras at home, consumers can choose according to their own preferences.

The fourth misunderstanding: blindly pursuing the photo function of digital cameras.

Nowadays, digital products are more and more advanced, and digital cameras have the function of taking pictures. Many consumers also like to buy products that can take pictures when they buy digital cameras. They want to use one camera for two purposes, both taking pictures and shooting. This idea has been adopted by manufacturers, and now most digital cameras have camera functions to cater to consumers' tastes.

One machine can be used for two purposes, which can be said to be a development trend of digital camera products at present. But the current level of technology is not enough to achieve the perfect combination of two cameras. Many products only meet the requirements in the number of CCD pixels. Different types of digital cameras have different imaging qualities, good and bad, but no matter how good they are, they are not as good as real digital cameras, so their shooting effects are not as good as real digital cameras. Consumers must understand that the images taken by digital cameras are all in MPEG4-4 format, which are all composed of * frames. At present, the best digital camera can only achieve 30 frames per second, but the image can only achieve 640*480, which is nothing compared with digital cameras.

So ordinary consumers should not think too much about using digital cameras as digital cameras. Because even manufacturers will not give up one of the markets and combine them for sale. The same is true for products such as E-shot, whose camera function is also in MPEG4-4 format, which is not a real movie format.

The fifth misunderstanding: blindly believe in brand effect

When buying a digital camera, many people will consider what brand of machine is good, and then find this brand of products to buy, but forget to investigate where it is good and what is the difference with other brands of the same grade. In the end, it may end up as "brand name is not practical". It is often heard that "buying Sony has face and it is fashionable to take it out". In fact, the brand reputation of digital cameras is very important, but for ordinary consumers, it is necessary to have a comprehensive understanding of the products of various manufacturers, read more materials and test the machines on the spot, so as to know yourself and know yourself. "Application is the best"! Buying a digital camera is not just to save face.

At present, there are many manufacturers of digital cameras in the domestic market, such as Sony, Canon, Olympus, Nikon, Kodak, Ke Mei, Fuji, Panasonic and Samsung. Its products are of good quality and each has its own advantages in function. Each manufacturer's products have their own characteristics. Choosing the right model according to your own needs can bring endless fun to home, travel and work, but it is unrealistic to blindly pursue brand effect. A good brand doesn't mean that all its models are good, right?

It is the most important thing to choose a digital camera that suits your appetite according to your own needs. For example, if you need many automatic functions, then it is possible that Nikon's machine is suitable for you and Canon's model is suitable for you. MM Choosing a digital camera may require a compact appearance, etc. All this should proceed from reality. Blindly looking at brands is very harmful.

The sixth misunderstanding: blind pursuit of technical parameters

Some young consumers are interested in new things and are very enthusiastic about new technologies. There are often arguments about the parameters of some digital cameras in forums. In fact, some parameters are very important to consumers, such as the size of CCD, optical zoom factor and so on. But some parameters are of little significance to ordinary consumers, such as the maximum shooting time, what kind of CCD to use, what kind of lens to use and what kind of lens motor to use. These values have no practical significance for mainstream consumer digital cameras. Unlike products that use SLR, a little progress in technology is a sign.

As a family digital camera enthusiast, you must remember that these technical parameters are only for reference when purchasing. Don't spend too much energy to pursue such and such parameters. It is better to inspect the market, understand the market and avoid being calculated by JS. Because the performance parameters of general household digital cameras are not very different, these small technical differences can be ignored in the final finished product, and the impact on the image can not be distinguished by the naked eye, so since you are for general use, don't "worry" about some parameters and argue endlessly:) Only when you buy a camera do you find that these functions are useless after several uses, on the contrary, you have to spend money to buy them.

The seventh misunderstanding: the forgotten corner-the types and endurance of batteries

When buying a digital camera, you should also know the type of battery used. Generally speaking, digital cameras using special lithium batteries and nickel-hydrogen batteries can not only save a lot of money for users, but also greatly extend the shooting time. Generally, batteries are not rechargeable, and consumers have to keep buying them to ensure normal use. Over time, this expenditure will definitely not be a small sum.

At present, there are almost two kinds of digital cameras on the market: tweezers hydrogen rechargeable batteries and smart lithium batteries. The advantages of tweezers hydrogen rechargeable battery are relatively low price, long service time and relaxed requirements for the use environment. If the battery is dead, it can be replaced with No.5 alkaline battery, which is economical and practical. The disadvantage is that the memory effect of the battery is larger than that of the smart lithium battery, which is not environmentally friendly and takes a long time to charge. The advantages of intelligent lithium battery are short charging time, lighter weight than tweezers hydrogen rechargeable battery, environmental protection, and almost negligible memory effect. The disadvantage of this kind of battery is its high price and poor compatibility.

Consumers choose the type according to their own preferences when purchasing. As far as the current situation is concerned, it is recommended that the hydrogen rechargeable battery for household tweezers has low overall cost and good compatibility. For consumers who need lightweight digital cameras, lithium batteries are a good choice.

Myth 8: Only "Zeiss" and "Lycra" are "professional" shots.

In order to leave an inscrutable impression on consumers, some manufacturers often claim that their products use professional lenses. Consumers who are not familiar with cameras, such as Zeiss, Nicole, Leica and Schneider, will inevitably believe it and be led by it until they are fooled.

In fact, this phenomenon is not uncommon. Consumers who don't know much about digital cameras but want to realize their dreams as soon as possible are often common "victims". We can't say that "Zeiss" and "Leica" are not good, but "Zeiss" and "Leica" are not all good shots, are they?

Generally speaking, the most famous optical lens manufacturer in the digital imaging industry is Carl? 6? 1 Zeiss, Nicole, Lycra, Schneider. Zeiss and Leica are generally used in camera and space imaging in professional fields, while Nicole and Schneider are mostly used in professional digital and SLR fields. The lenses used will be marked with eye-catching marks and marked in detail in the instructions, which can be easily found by consumers when they inquire online.

For example, Sony and Panasonic generally use "Zeiss" and "Leica" lenses. In fact, we should not be overly superstitious. Because these lenses are also authorized by Zeiss and Lycra, they may not really come from the original factory.
