1. Price
The reason why the price is put in the first place is because everyone basically has a psychological limit price when purchasing a machine. Here, I want to remind everyone that we must avoid only pursuing high prices when setting prices.
High price will definitely improve performance, just pay attention to whether some performance is suitable for you, and some just improve the quality of photo shooting. For example, Sony's TRV 16E is different from 750 yuan's TRV 18E, but the main difference is that the latter is superior to the former in static shooting ability. Generally speaking, there is no need to buy the latter, which can completely save your money and will not affect the performance you require.
2. Charge coupled devices
CCD is one of the most important indicators to determine a digital camera. When choosing CCD, we should consider the following aspects:
Pixel of 1.CCD: basically determines the grade of digital camera. At present, the middle and low grades are generally around 800,000 to 6.5438+0 million pixels, and the middle and high grades are generally above 6.5438+0.2 million to 2 million pixels. Pixel size directly determines the clarity, color and smoothness of the captured image.
Second, the number of CCD. 3CCD is much better than a single CCD camera, because the single CCD is restored with a single color, and 3CCD is restored with each color, so that the three blocks are responsible for red, green and blue respectively, which will not cause color cast of adjacent pixels like single chip centralized restoration. Moreover, the performance of 3CCD in anti-shake function and minimum illumination is better than that of a single CCD camera, so of course, choose an affordable 3CCD.
Third, the area. Don't underestimate the area of CCD. Other indicators are the same. The image quality of small area CCD is relatively blurred, and the color reproduction richness is also poor. The area used for shaking is also much smaller, and the anti-shake function is of course relatively weak.
camera lens
Like a digital camera, the lens is also an important factor to determine the imaging quality. First of all, look at the zoom ratio, which refers to optical zoom. The greater the optical zoom ratio, the greater the degree to which we can choose the scene size, which will bring great convenience to our composition when shooting, which is the same as the zoom lens of a camera.
Second, it depends on the aperture of the lens. If the aperture is small, even large pixels can't be photographed well in the dark. In other words, it will become a bottleneck of digital camera imaging.
4. Shape and volume
These two indicators are very important for home cameras. Users must focus on these two aspects if they want to play dazzling and convenient.
The machines used by our buyers are generally recreational, so we should consider the appearance. The other is size. Household cameras are generally carried with you when you go out, so it is very necessary to be small and exquisite, which can be carried easily and make room for your other supplies. Most importantly, you can take any posture, and you don't have to limit the shooting angle because of people's standing posture.
5. Operation menu
Ordinary users may never play with numbers, so the simplicity of the operation menu has become a necessary condition for choosing a machine. At present, the operation menu of most digital cameras is very simple, but if there is really no foundation, there are two kinds of menus to choose from, Chinese menu and touch menu. Needless to say, the touch menu can be operated by pointing to the LCD screen, which is very convenient and suitable for digital beginners.
6. Still image shooting ability
Some digital cameras can also be used as digital cameras when your requirements are not very high, but one thing must be paid attention to when purchasing. Although some machines can also take pictures, the images are not recorded on the memory card, but on the DV tape. You can't expect the quality of this camera's photo function. If you have the idea of using the camera function, it is strongly recommended not to buy such products.
7. LCD viewfinder
There is nothing profound about the LCD viewfinder, mainly that the brightness should be high enough, the pixels should be large enough, and the larger the area, the better. 2.5 inches and 3.5 inches are popular now, as long as you pay a little attention when buying.
8. Accessories
Don't underestimate the accessories, it also plays a key role in the normal operation of your love machine. Be sure to pay attention to the battery standby time. Generally, the shooting time of the battery is relatively short. If you have a better battery, you can open the viewfinder when using it and take as many pictures as you want. That would be great. There is also a memory card, as well as various wires (matching with various models of machines), and some machines may have other accessories. Pay attention to check whether all the equipment on the cargo list has been delivered.
Of course, don't forget to pay attention to the prices of spare batteries, backpacks, DV tapes and other accessories. Although it is not a big item, it adds up to a lot, which will have a certain impact on your future shooting process.
9. Guarantee
Although generally speaking, the failure rate of digital products is very low, just like the TV set at home, it is still intact for three years, five years or even ten or eight years. However, nip in the bud is of great benefit to our use, so I suggest that you must pay attention when buying: First, buy a better manufacturer brand and try to have a maintenance station in the local area, which may be of great benefit to your use. Second, be careful not to buy parallel imports.
Selection misunderstanding:
Like many digital products, due to the influence of media publicity, consumers often have certain misunderstandings when buying, and pursue some functions that are not the most important critically, while ignoring the really important factors. Don't fall into such a misunderstanding:
1. Don't just recognize the brand.
When buying a digital video 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 from other brands of the same grade. In the end, it may end up in a situation that "famous brands are not practical".
In fact, the brand reputation of digital cameras is very important, and the specific parameters are also very important to us. Before buying, we should fully understand and compare the product performance parameters of various manufacturers and find the one that suits us best.
At present, there are many digital camera manufacturers in the domestic market. Sony, Panasonic, Samsung, Canon, JVC, Sharp and other products have good quality and their functions have their own advantages. 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 all its models are good, do you think?
2. Don't blindly pursue the photographing function of digital camera.
Nowadays, digital products are more and more advanced, and digital cameras already have the function of taking pictures. The number of pixels in some products has reached 2 million or even 3 million, which is comparable to mainstream digital cameras. Many friends also like to buy products with high pixels when buying digital cameras. They want to use one camera for both purposes, so they can take pictures and shoot.
It can be said that the dual-use of one camera is a development trend of digital camera products at present, but the current level of technology is not enough to achieve the perfect integration of two cameras. Many products only meet the requirements in terms of the number of CCD pixels, and the picture quality of different models of machines is different, good and bad, but no matter how good it is, it is not as good as a real digital camera, so their shooting effect is not as good as a real digital camera.
Therefore, it is enough for ordinary families to use a machine with about 800-/kloc-0.0 million pixels for daily family photography, and there is no need to spend thousands of dollars to pursue high-pixel photography. For home digital cameras, we mainly use them as digital cameras. There is no need to demand such a high still image effect. If high static photos are required, it is more appropriate to buy a digital camera with more than 3 million pixels.
3. Don't blindly pursue night vision.
As the name implies, the so-called night vision function is that digital cameras can shoot images visible to the naked eye even when the light is very dark or even completely absent. At first glance, this function is very practical, because we often encounter insufficient light when shooting. If the "night vision" function is really so magical, it will be much more convenient for us to shoot scenes such as night scenes.
At present, digital cameras produced by major manufacturers in the market have night vision functions, such as Sony's infrared night vision and ultra-infrared night vision, Panasonic's color night vision function, and JVC's color digital night vision. Many users were interested in night vision before buying it, but found it useless after buying it. The image taken by this function is monochrome or monochrome. Therefore, the "night vision function" of digital video camera should only be used under certain shooting conditions, and the shooting picture effect is poor. When the light is insufficient, try to make up the light instead of relying too much on the "night vision" function.
At present, most buyers buy digital cameras in order to travel abroad or shoot some videos of family daily life. I believe that not many people will often use these "night vision" functions. Therefore, when you buy a digital camera, you can regard the "night vision" function of various brands as a small additional function, without considering its advantages and disadvantages too much. You should pay more attention to the selection of important functions such as CCD, lens, zoom and anti-shake.
