Please recommend some cameras.

First of all, of course, Sony, the world leader in audio-visual technology. Its products are small and exquisite, fine in workmanship, and pay attention to every detail and the user's operating experience. In terms of color performance, it caters to the preferences of ordinary consumers and is more bright and bright. Sony's DV player has done a good job in auto focus and auto white balance, and the focus is fast and stable. When it comes to the shortcomings of Sony products, there is probably only one-price. Among the products with the same index, the price of Sony products is always higher than other brands.

Sony's DV product line is very complete and there are many models, which are mainly divided into the following series: DCR-TRV is a horizontal holding machine, DCR-PC series is a vertical machine, DCR-IP series is a MicroMV machine, DCR-VX series is a shoulder-mounted professional machine, and DSR series is Sony's DVCAM professional machine. In terms of product positioning, it can be roughly divided into three categories: entry-level home computers, high-end home computers and professional computers.

High-end home machine. The main models are TRV940E/TRV950E, PC 10 1E and PC15e/PC120e.

940E/950E adopts 3CCD imaging element with millions of images, which belongs to the top model in household DV. In addition, it also has 12 times optical zoom, 3.5-inch touch LCD screen and optical anti-shake system. The difference between 950E and 940E is also the Bluetooth communication function.

10 1E, 1 15E/ 120E are vertical models, and the number of CCD images of10/0e is1070,000,/kloc. 1 15E/ 120E is also equipped with a pop-up smart flash. Compared with 1 15E, 120E has the function of directly accessing the network by using attachments.

Let's take a look at Panasonic, another major producer in the DV field. Panasonic's DV products always try to control the cost on the basis of meeting the functional requirements, that is to say, DV machines with the same performance index are always cheaper than Bisogni's, and even the functions are more perfect than Sony products of the same grade. However, Panasonic's DV machine is not so exquisite in appearance, workmanship and operating feel. And in terms of color performance, Panasonic's DV Bisogni is more peaceful and can be said to be closer to the real thing. Panasonic's product strategy is that as a market follower, the products developed by Sony will definitely have corresponding models, which are not less functional than those in Bisogni, but cheaper, giving consumers one more choice.

High-end home machine. The main models are GX7, EX2 1, EX3, MX8, MX350, etc. GX7 has CCD elements with millions of images, and the resolution of static images can reach 1280x960. Leica lens is adopted, which has the functions of quick start and wire control. GX7 is cleverly designed. Its flash is fixed on a ring behind the lens and can rotate 360 degrees around the lens.

EX2 1 is an alternative design of DV machine, which reflects the trend of convergence of DV and DC from another side. EX2 1 consists of two detachable parts. The upper part is a complete digital camera, which can take digital photos of 1200x900. If combined with the camera part below, the original DV face will be restored. Moreover, EX2 1 can record 240 minutes of voice with its own SD card, which is equivalent to an interview machine. EX2 1 Such a unique design, its target users are likely to be journalists.

EX3 is a vertical model, the overall size is only 49 (width) x 108 (height) x86 (depth) mm ... 57 Vientiane CCD elements are used, and the fast zoom speed of EX3 is also a feature. In addition, it can select any part of the picture for digital amplification of 10 times when playing an image.

The appearance of MX350 is similar to that of MX8, but it is much more powerful. First of all, MX350 adopts 1/4 inch 3CCD element, and the image number is as high as 18 10000. In addition, MX350 has an optical zoom of 12 times and a 3.5-inch LCD screen, and other functions are similar to MX8. These ensure that MX350 becomes the top product of Panasonic family DV.

In addition to Sony and Panasonic, DV manufacturers include JVC, Canon, Hitachi, Samsung and Sharp. These manufacturers rarely produce DV models. Please choose a representative one to introduce:

GR-DVX/GR-DVP series of JVC company. JVC is the founder of vertical DV models, so there are many vertical models in JVC products, such as DVX40/DVX90, DVX709/DVX400, DVP7 and so on. The dimension of DVP7 is 43x 1 15x80mm and its weight is 350g. Using 102 Vientiane wide-angle CCD imaging, the LCD screen is only 2.0 inches due to size restrictions. The products of JVC company give people the impression that the images are true, concise and practical, and cheap. However, the focusing speed of JVC products has been unsatisfactory and should be improved in new products.

Matters needing attention when purchasing:

Which manufacturer's products to buy: this question actually depends entirely on personal hobbies and the degree of love for the corresponding brands. Before buying, we should focus on whether the brand has a perfect after-sales service system in China and whether it can provide warranty service for the products sold. Of course, different brands of machines have different images because of different design ideas: Sony products are gorgeous and sometimes almost exaggerated; Panasonic's product image restoration is more realistic, but it makes people feel cold.

Choose single CCD or 3CCD: It depends on what you bought this machine for. Because of the excellent performance of 3CD in color reproduction, if you are a professional or an enthusiast who cares about machine performance, you should consider 3CD machines anyway. However, if you just want to record the baby's growth process for ordinary families, such as patting the back, then you can buy a single CCD. After all, a 3cd player is much more expensive than a single CCD player, and the image quality of a single CCD is enough for ordinary families.

The number of pixels and the size of CCD: the number of pixels determines the clarity of the image, but under the current TV system, the clarity does not increase linearly with the increase of the number of pixels. When the number of pixels increases to a certain extent, it has no effect on the definition, so the number of CCD pixels in home cameras is about one million. As for the size of CCD, of course, the bigger the better, but now the CCD of household cameras is generally a quarter inch, and you have no choice.

Choice of lens: Of course, the larger the zoom range of the lens, the better. Note that the zoom range referred to here is an optical zoom range, which should not be confused with digital zoom. As for the wide angle of the lens, a large wide angle range can obtain a large shooting range, so many people will attach a wide angle lens to the lens of the original camera to obtain a larger wide angle. But if the wide angle is too large, the image will be distorted, so it can only be considered as a compromise.

Appearance of the machine: In this respect, it can be said that "turnips and cabbages have their own tastes". Whether it's selective or love at first sight, choose one you like. From the author's point of view, you should choose a small and exquisite one, because the love machine you bought may follow you to the grave and cross the mountains and rivers, so you should consider the convenience of carrying it. Don't think that a large machine can afford it. In fact, many machines with large shapes are just big shells. In addition, it should be noted that the machine of 3CD is bigger than the machine of single CCD, because its CCD is bigger.

Night vision function: Now many machines have night vision function, and many users are interested in it, but they think it is of little use after buying it. Indeed, the images taken by this function are either monochrome (black and white or green) or discontinuous, which will be uncomfortable for a long time, so this function is dispensable.
