I want to buy a digital video camera (small). I don't know what brand is better and has good performance.

When purchasing digital products, the specifications and parameters of products become the main basis for many consumers to compare, and digital cameras are no exception. But many parameters often confuse consumers, such as CCD, aperture, focal length, optical zoom and so on. Many consumers really don't know where to choose. In fact, the purchase of digital cameras is mainly based on sufficiency, and it is not necessary to pursue new pursuits excessively, and buy some digital cameras with flashy functions.

For example, many friends understand this truth. Digital zoom is enlarged at the expense of image quality, which is of little practical use. Optical zoom is more practical. The GS 1 1 launched by Panasonic this year has 24 times optical zoom, which is the king of zoom for home digital cameras at present, but it only sells more than 3,000, while the GR-D230AC of JVC is the same product launched this year, with only 65,430. In fact, the bigger the optical zoom, the better. The positioning and performance of GR-D230AC and GS 1 1 are different, so the prices are different, so they cannot be compared by a certain parameter. Although large zoom is very useful in some occasions, such as shooting wild animals, sports competitions, etc., we usually buy digital cameras to record some bits and pieces of ordinary life. Such a large zoom may not be fully utilized, so we don't have to pursue it deliberately.

Nowadays, many digital cameras also have some night vision functions, such as Sony's infrared night vision function and JVC's color night vision function, which are generally well publicized, but Sony will never tell you whether the pictures taken with its infrared night vision function are green or white. If you see these strange "ghost films" shot by the so-called "infrared night vision" function in green or white, do you still think these night vision functions are very useful?

Digital cameras pay more and more attention to the function of taking still pictures, but no matter how much they pay attention to it, they are very different from the photos taken by digital cameras. Otherwise, why do digital cameras always dare not claim to take "photos" and say "still pictures"? A digital camera can use a 1/3-inch CCD, while a digital camera is generally11.8 inch. In addition, white balance, autofocus, image processor, etc., digital cameras are not as good as digital cameras, and it is not surprising that the still images taken are very poor.

However, many manufacturers still use a set of methods of digital cameras to advocate the function of digital cameras to shoot still pictures: pixels. Sony introduced the 3-megapixel PC330E, followed by the 3-megapixel PC350E and HC88E, and Panasonic also introduced the GS400, which is said to be able to take 4 million still pictures. In fact, the improvement of pixels can basically not improve the static image quality, and the high-pixel picture can only develop large-size photos. Moreover, for example, Panasonic GS400, its 4 million pixels are realized by AXIS technology, which is also an advanced pixel interpolation system. Think about it, how much water will there be in the interpolated pixel?

Choosing the right digital camera, such as pixel and optical zoom, is just one of the considerations. We should pay more attention to the quality of the picture, such as whether the film is clear, whether the color is distorted, and how the white balance effect is, but these are often without parameters for your reference. You can shoot it directly when you buy it, and then collect it with a computer to see the effect, which may be more troublesome. The easiest way is to talk directly about the digital camera connected to the TV after shooting, so that you can really feel the shooting effect, whether the color is off color and whether it is clear. Never watch it on the LCD screen of a digital camera, because the effect displayed on the LCD screen will be very different from the actual situation.

Consumers should choose digital cameras according to their performance characteristics, practicality, use and their own economic ability. At present, there are two kinds of Sony digital cameras, one is digital 6mm format, and the price is about 1000 yuan. Another digital 8mm digital camera was developed by Sony on the basis of Hi8mm and Digital8 mm formats. Its size, shape and weight are similar to those of Hi8mm frame, but its function and clarity are the same as those of digital 6mm frame, and its price is lower, ranging from 6000 yuan to 1000 yuan. JVC GR-DVX 90 new digital camera not only has built-in flash, which is convenient for shooting still images, but also can record 20-second dynamic compressed images (MPEG file format) on random multimedia cards. Panasonic pana? SonicNV-MX300 new 3CCD digital camera, the image pixel is 1.8 million, and the resolution is 1 152× 1568, which has reached the highest index of the current camera. Sharp VL-PD6E digital camera, its LCD screen can be detached from the body, which is convenient for monitoring. Canon CanonMV3i, MV3imc and MV300i digital cameras have become the objects of consumers' purchase because of their beautiful appearance, comfortable feel and compact size.
