What parameters are more important to buy a card machine? With so many pixels, wide angle and zoom, I don't quite understand.

1, brand; There are several brands of card machines in China, such as Panasonic, Sony, Canon, Nikon, Fuji and Casio. Don't be surprised if you don't mention them. Every brand has its own advantages.

Panasonic-the color is cold, and Lycra-certified lens is adopted, so the imaging quality is guaranteed. We have the strength to produce CCD, and the image quality is guaranteed. The optical anti-shake technology was first developed. It's easy to get clear and unambiguous photos, with less advertising investment and relatively cheap cameras and accessories.

Sony-carl zeiss certified lens, the imaging quality is also extraordinary, its own strength to produce CMOS, guaranteed image quality, stylish appearance, multi-functional and practical, easy to use screen, large and clear, more advertising investment, cameras and accessories slightly expensive.

Canon-the color is warm, and the self-produced lens is used, and the imaging is also very real. Have the strength to produce CMOS and become a first-line brand. It has strong noise control and high sensitivity, mature electronic information technology, its own advantages in the digital field, more advertising investment, and relatively expensive cameras and accessories.

Nikon-the color is cold, using nikkor lens. The production process still continues the traditional style, and the appearance is not so fashionable and fancy. Compared with Canon and Sony, the advertising investment is less and the function development is relatively less. But it is still excellent in imaging. Friends who do not care about fashion can choose Nikon.

I won't introduce many other non-first-line brands. The first-line brands I mentioned are all based on the sales rankings of Japan, Europe and America, so if the rankings change, I can accept others' saliva!

2. Pixel: This is only related to the size of image magnification, and has nothing to do with image clarity. If you take a 6.5438+megapixel camera, the picture can be developed to 36 inches at most. If you take a 6.5438+0.2 megapixel camera, the picture can be enlarged to 40 inches at most, then an 8 megapixel camera is enough for your real family. Only now 1200 has become the mainstream of the market, and 20 12 has grown to160,000 pixels, probably because there is no such thing as a digital camera card machine to upgrade, so we can only make a fuss about pixels.

3. Zooming: This is related to the distance between image enlargement and reduction. When you need to take a long shot, you need a camera with a larger zoom. At the same time, we should pay attention to choosing a camera with good anti-shake. Otherwise, it is difficult to take photos after zooming, and zooming should be optical. Digital zoom is meaningless and will reduce the image quality.

4. Screen: This has little to do with camera performance, and it will only be used when you play back photos. To really see the effect, you should take it home and put it on the computer. Don't deliberately choose those touch screens and large screens, which consume electricity and are easy to break down. In addition, the cost of manufacturing a touch screen has also increased. If it is practical, just look at the screen clearly, there is no need to choose too good one.

5, camera function: Now there are several levels of digital camera camera camera function, that is, 640X480 resolution, which belongs to standard definition camera, and the definition is average; And 1280X720, which belongs to HD. Generally, the high definition of digital cameras belongs to this category, but at present, there are some high definitions of 1920X 1080i, which have higher definition. The best is 1920X 1080p. If you follow the letters and can enlarge them during shooting, it will be very convenient for you to shoot videos. You don't need to walk or move. If you can't zoom, you can only walk around. Hey, you'll be tired then! In addition, the shooting function of digital camera is different from DV. Making short films is the same. After shooting for about ten minutes, I will stop by myself, and then I will start shooting the next paragraph, which is a paragraph by paragraph, while DV is recorded continuously without stopping. If you want to use the video shooting function, you should also buy a high-speed card, at least level 6 or above. It's best not to choose Kingston as a brand, but to choose some good brands, such as Sandisk in the United States and Lei Kesha.

6. Anti-shake: At present, anti-shake can be divided into optical anti-shake and electronic anti-shake. Of course, optical image stabilization is better. Before buying a camera, you must know whether that model is optical anti-shake. Some salesmen know that a camera is electronic anti-shake and will not tell customers. They mainly make money by selling machines and using anti-shake cameras, so that you can take clear photos even if you shake badly, such as taking pictures of the scenery outside in the car.

7. Manual: Generally, digital cameras are automatic, and the aperture and shutter are automatically set. Just press the shutter to shoot. With manual operation, these things need to be adjusted by themselves. Different parameters such as aperture, shutter, photosensitive value and exposure value have different shooting effects. Professional photographers are familiar with the changes of these parameters before taking sharp photos, so if you are interested in professional cameras, you can choose a card machine with manual function first.

8. Wide angle: This has something to do with the lens. If you make a wide-angle lens, you can let the lens accommodate more scenes at the same distance, and sometimes you can let the lens accommodate a wider scene without retreating. There are several specific standards, 30mm, 28mm, 25mm, 24mm, 35mm, which are called standards, and that is not with wide angle, 30mm is a small wide angle, and 28mm is a standard wide angle.

9. I won't talk about other fancy functions. You should learn more and see more by yourself. You can't learn anything without hard work!
