2 Look at the zoom size (generally, the smaller the zoom, the better the lens imaging quality, and the appropriate zoom size is convenient for composition, and it is appropriate to choose 3 times the size);
3 See if the lens is wide-angle (large viewing angle when taking landscape photos);
4 See if it is optical image stabilization (novice is very important);
5 look at the precautions for buying a digital camera.
1. When you want to buy a digital camera, you can go to relevant websites to browse the basic situation first, such as the DC section of Zhongguancun online website: there are news, digital camera parameters and comments from netizens. Here you can find detailed parameters, prices and other information of almost all brands of digital cameras. Another example: the digital camera version of Pacific Computer Network, like the above website, can find a lot of information you want to know. On these websites, you can have a general understanding of digital cameras.
2. Learn some basic knowledge of digital cameras, such as CCD, pixel, aperture, focal length and anti-shake. You need to know and master these basic knowledge in advance. This kind of knowledge, look it up online.
After the above study, you will know something about digital cameras. At this time, you can pre-select several models of machines in order to further inquire about the situation from the Internet. For example, if you choose Canon A620, its key point is * * *. For example, there was a time when some models of Nikon machines were used for a short time, that is, the display screen was tilted. When most articles mention a defect, you should stop choosing this machine. Here's a little. Read the evaluation report.
4. Here is another point. When buying, be sure to ask whether it is licensed or parallel, and whether there are any gifts. Please explain here.
After the above steps, you are no longer a layman of digital camera. You already know something about the machine you want to buy. At this time, you can check some posts related to this type of machine on the Internet to focus on understanding the problem. If necessary, post in the online section of digital electronics or photography for advice. At this time, the pertinence is strong, and you will know whether the selected machine is suitable. I hope the above introduction will be helpful to netizens who want to buy digital cameras. When you choose the model, the rest is to choose the model.
2. Precautions for purchase:
1, before buying, be sure to ask whether it is licensed or parallel, and then you can check the machine: first, check whether the seal on the box has been opened. If it has been opened, it means that the machine has been moved, preferably unopened. Secondly, check whether the machine numbers on the box, the bottom of the machine and the warranty card are consistent.
2. After opening the packing box, take out the instruction manual, which contains a list, and check it with the physical objects one by one, such as memory cards, batteries, chargers, data cables, optical drives, shoulder straps, bags, etc. It's usually in the instruction manual. There must be some. If not, it means that the dealer is corrupt. It doesn't matter if the battery is AA alkaline battery, but the lithium battery should be carefully checked, whether it is original or otherwise, to prevent the dealer from changing the package. As for manual operation, it can be seen whether it is parallel imports. Generally, if there is only English or traditional Chinese, it is parallel imports (of course, some parallel imports may be accompanied by a simplified Chinese manual with poor quality).
Next, you can try the machine. At this time, you must pay attention to the work of loading memory cards and batteries into the machine. You'd better not do it and ask the waiter to help you install it, because you are not familiar with the machine. If you install it backwards, something may go wrong. Next, you can use the automatic file (available on all models) to take pictures. At this time, if you are indoors, your flash should flash automatically. If you are outdoors, your flash should not flash on sunny days. Take a few photos and you can play them back. In the process of shooting, you should also carefully check whether there are defects (white, blue, etc.) with fixed bright spots. ) on the display screen;
The next step is more important, but many dealers don't do this job, that is, test the bad points of CCD, provided that he has a computer and a small software to test the bad points of CCD. Cover the lens with suede or other objects first, and shoot with the largest and smaller apertures (of course, you can do it manually, and if it is automatic, the exposure time will be longer), and the speed can be arbitrary, just take 2-3 shots. Use the card reader to transmit data to the computer, open the small software to test the bad points of CCD, browse and find the photos just taken (they should all be black when viewed with the image software), click Test, and the results will appear immediately. If the bad point is 0, then your machine is good. After that, you can test several others. If they are all 0, the test is complete. Note here that sometimes there will be some noise, which is normal. If you test a normal photo, you will find that there are many bad points and noises, which is normal;
5. Next, you can operate the machine by yourself, take some photos and feel the machine. At this time, you can change different gears, such as P (automatic) A (aperture priority) T (shutter priority) M (manual); There are also scene modes (such as night scene, snow scene, portrait, night scene portrait, fireworks, sports, children and so on). ), can be tested in turn. For some settings of the machine, you can make some necessary settings (such as white balance, ISO, image format or size, etc. ) read the instructions. Generally, the higher the end of the machine, the more settings, such as SLR, many items, it is impossible to get familiar with it at once when purchasing the machine. 6. At this point, the inspection of the machine has been basically completed. If it is a lithium battery, it may be because it was not fully charged before, so the power of the machine has been used almost at this time. At this time, you can turn it on and off several times to see if the display is normal.
7. The following is to put the machines in the box, count them one by one, and then ask the dealer for gifts. Here, obviously, there are two kinds of gifts for buying digital cameras. One is the activities organized by production companies, which are generally reported in their official website or digital related websites; The other is the activities organized by dealers. You can ask the merchant before buying this gift. Regarding the issue of invoice, it depends on whether you made it clear when you bargained for money before, because if you invoice, the merchant will definitely add 4%. Of course, parallel invoicing is of little significance. Anyway, there is something wrong with the machine, and it has to be sent to the dealer for handling. It is up to you whether the licensed goods are invoiced or not. If you don't open it, you have to find a dealer if you have any problems. It's a little troublesome. If you open it, you have to pay more money.
8. Let's talk about the inquiry of true and false goods. Now many companies use 16-bit code to query. Generally, there are labels on the packaging. After scraping, 16 digits will be displayed. You can call or log on to the relevant website to check whether it is genuine. At the purchase site, you can call to inquire, but remind you that 16 must not be entered wrong. If you enter a wrong number and just make an inquiry, you will be immediately informed by phone that the product has been inquired;
9. Finally, there is another question that people don't pay much attention to, that is, do you want to register online? At present, most companies have online registration. You can log on to their official website and enter the necessary information to register. If you register, your purchase date has been stored on their server. But some companies, such as Ricoh, want to extend the warranty period after registering online. After online registration, the warranty period is extended from one year to one and a half years, which is very tempting. I once registered Canon's machines, but there were no preferential activities after registration. I just received a successful email on the day of registration, and then it was gone.
