How to determine the authenticity of the 4G card What models are there in SONY

First look at the outer packaging, Chinese, there is an anti-counterfeiting label in the upper left corner, and there is a serial number on the back to be consistent with the card is true. If you are really and not at ease, it is recommended to go to Sony's after-sales purchase, about 800 yuan.

This thing is the most silver, so that the trembling is good and the front is to go to the physical store to buy, and the later maintenance is also convenient, I bought it in Suning in November this year** in 1200

Sending cards, sending bags, tripods, or whatever, it's 1300 plus an original battery.

I'm dizzy, what are you doing copying so many other people's stuff above? Isn't it disgusting?

One is to look at the buying** The latest line sticks can be found on the Internet**.

One is to look at the appearance, the workmanship is more fine, especially the position of the gold finger, and the other is to look at the freebies, the licensed memory stick has a converter, and the other that turns into a long stick is to look at the transmission speed, the speed of the licensed and high-quality group sticks is not much different, but if it is an inferior memory stick, it can have a very obvious low-speed transmission speed.

Is it a stick to show support in the machine? ”

psp, even if you plug in the stick, there will be no hint.。。。

The most convenient way is to test the read and write speed with the atto disk benchmark... The read and write speed of the group stick is very slow.。。。 The reading and writing speed of the traveling stick is about 15 ms for the normal one, and about 30 ms for the high-speed hx

The group rod is generally in 10m s is very remarkable...

Of course... The best thing to do is to buy it directly from a regular store... The one on Jingdong is not expensive...

No, it's licensed, it's numbered, go to Sony and lose it, and it will tell you if it's licensed.

You're talking about how to distinguish parallel goods from licensed goods. Counterfeiting of such high-tech products is difficult. Let me tell you how to distinguish parallel goods from licensed goods.

Most parallel digital cameras are not produced in China, often there is no Chinese manual, the instructions are Japanese or English (Japan pays attention to environmental protection, the packaging boxes are recycled paper and simple printing), Hong Kong licensed goods (we call parallel goods) instructions are Chinese traditional. Generally, it is packaged in Japanese and Chinese traditional, and there is no Chinese on the driver, software, etc. Even if some parallel goods provide Chinese instructions, they are often coarsely printed.

Some dealers clearly tell you that it is a parallel import, and then attach you a Chinese manual of a similar model of camera. The licensed packaging box should also carry a warranty card, and the card should also be stamped with a legal warranty seal. Let's take a general look at whether the body model on the digital camera housing belongs to the product model sold in the Chinese mainland market.

For specific product models sold to the Chinese mainland market, you can inquire about the local digital camera special repair center, or directly call the service ** of the digital camera manufacturer. The most effective way to identify whether a product is licensed is based on the serial number of the fuselage. Since each digital camera has a unique code, users only need to call the manufacturer's domestic technical support department, branch **or free inquiry provided by the manufacturer**, to know whether the digital camera they purchased is licensed.

How to choose a digital camera For most people, spending thousands of dollars on a digital camera is not a trivial matter. I'll tell you all about it. First of all, let's talk about where to buy this digital camera.

Actually, you can buy it (digital camera) in a store that sells a camera and a store that sells a computer. But the choice of store is an important thing. You must choose a store with a certain scale and a certain reputation to buy this relatively valuable product.

I don't need to say much about the reasoning in this, everyone will understand. Next, let's start to choose a digital camera, which first depends on whether there is a problem with the appearance of the camera. Whether there are scratches or bumps, in fact, it doesn't matter if there is a little problem, the first condition is to see if there is a problem with its internal function and performance.

Look at the lens (Carl Zeiss lenses are the best) Look at zoom - home zoom is not easy to be too large, generally four or five times See if there is any stabilization - anti-shake generally has electronic image stabilization and optical image stabilization, the latter is better See if there is a wide-angle camera - it is best to have it at home (this can make the captured image better) Remember that the wider angle is the smaller and more advanced the better (for example, the general configuration is 30mm, which is not counted, and 28mm is considered to have a true wide angle) The second step in choosing a digital camera is that you have to put the battery in it and put the memory card away. Now that you have the battery and the card, you can turn on the power of the camera and let the lens be exposed. The inspection of this lens should not be sloppy at all, because the lens is directly related to the actual quality of the image. The surface of the lens should be free of scratches, there should be no obvious bubbles inside, and the coating on the surface should be intact.

Now you check its zoom performance again, you see. If all these things are checked and it proves that there is no problem, the inspection of the lens is over. Generally speaking, the lenses of digital cameras are produced by digital camera brand manufacturers, such as Nikon, Canon, Minolta, Olympus, and Fujifilm.

However, many manufacturers who do not develop lenses by themselves will choose high-quality digital lenses from famous brands in the world to match their cameras when making digital cameras. For example, Panasonic's digital camera uses a lens from German Leica, Sony uses a lens from Carl Zeiss from Germany, and Kodak uses a lens from Schneider. These examples will tell us that manufacturers must pay great attention to the quality of lenses.

This digital camera is a complex electrical product, and it used to take a long time to boot, but now it is getting shorter and shorter. Generally, it takes 2 seconds to enter the shooting state.

The easiest way, look**, awesome** is not too cheap, in addition to the warranty card can also be seen, you can call Sony's 800 query confirmation. The following is for your reference:

2L's nonsense, now Sony's 4G stick is only 149 to buy on the official website

What is the difference between the original stick and the set stick??

I don't know how to identify anything else.

The easiest. You see** is done. More than 2g, less than 200 are fake.

If you want to buy an original stick, just go to a specialty store, and if you want to buy a set of sticks, video game stores are everywhere.

About 70 is enough for online shopping, and at least 90 for physical stores. Online shopping with compression function and high-speed transmission costs about 110, and about 12G of files can be stored. It is easy to distinguish the real from the fake, and there will be an anti-counterfeiting verification code on the packaging of the licensed goods, and you can send a text message or check the authenticity on the Internet after you get it

My high-speed (claimed transfer speed of 30MB per second) Sony 4G was bought for nearly 400 at the time, and now it costs about 300.

About 250, it is more difficult to distinguish counterfeits, it is recommended to go to a store with a good reputation!
