What problems should I pay attention to when buying digital cameras?

When buying a digital camera, please pay attention to the following aspects:

1, CCD size, which is the key to imaging quality. The larger the size, the better the imaging quality. Generally choose 1/2.5 inches or more. 11.8 or11.7 inch is better.

2. Effective pixels of CCD. The effective pixels of CCD are generally above 5 million. The mainstream of the average family is 5 million last year and 6 million this year. The function of pixel size is how big a photo can be printed. High-quality photos with a resolution of 5 million pixels and a maximum print size of 50 x 75 cm (20x30 inches). Pay attention to the high quality, that is to say, it is not bad to print a larger one. Do you think that ordinary people need to use100000 pixels? Actually, 3 million is enough.

3, lens size. 3 to 12 times optical zoom, generally 3 to 4 times is enough, and more than 6 times is the telephoto machine; Choose a wide-angle 28mm lens size; Telephoto choose 200mm to 400mm and don't go to digital zoom. Of course, it would be better if we can have a wide angle of 28mm and a telephoto of more than +300mm, which can be more suitable for shooting in various occasions and realize the desire to travel around the world in one mirror, but there are too few such models, only a few models, and there are not many objects to choose from.

4. Display screen. 2.5-inch display, more than 200,000 images, the display effect of this display is quite good; Of course, there is also a rotatable display screen to choose from, and the rotating screen will bring more convenience to your framing. It depends on the size and also on the pixel. Canon's largest is 3.0, but the pixel is only 1.7 million, and the effect is not very good. If you buy a 65438+700,000-pixel display, 2.5 is better than 3.0, and you can't be greedy. Of course, like Sony Panasonic's 3.0-inch, 230,000 pixels, the effect is particularly good.

5. Animation function. Support mainstream animation function with 640×480 pixels and more than 30 frames per second. It would be better if you can take still photos, do optical zoom, do optical anti-shake, edit animations and cut still photos after shooting.

6. Manual function. If manual operation is required, it depends on the manual function (m, a, s). It depends on everyone's hobby. After all, most people still like full automation, but if you want to learn photography, the more powerful the manual function, the better. It is best to have aperture priority, shutter priority and manual exposure.

7. Body size (shape and color), battery type (capability), anti-shake and so on. If you want an anti-shake model, you should generally choose an optical anti-shake model. Batteries are usually lithium batteries. All right.

Of course, there are aperture size, shutter speed, sensitivity and so on. But if there are no special requirements, these configurations will match the grade of the whole machine. To be high, you need a large aperture of F2.8, a high-sensitivity ISO3200, a 60-second slow shutter, a 1/4000-second fast shutter and so on.

Recommended:

It is recommended to choose a general household card machine: small and stylish, easy to carry and control, and some with double anti-shake and 28mm wide angle. Sony T 10/T50, Panasonic FX07/FX50 and Canon IXUS850 are all very good card machines. Among them, Sony T 10 or T50 is more fashionable in fashion, and Panasonic FX50 is more practical in fashion.

Panasonic FX50- Lycra lens 28mm wide angle+double anti-shake+super animation +3-inch large screen+small and exquisite.

The current price is 2650 yuan. At this price, compared with other models, FX50 has a wide angle of 28mm and super animation, which is quite practical, especially wide angle. You can take a wider picture when taking scenery, and you can accommodate more people when taking group photos. Panasonic's exclusive optical anti-shake technology is the best among all anti-shakes. Compared with Sony Canon equivalent card machine, only FX50 has so many features. In front of many card machines, Panasonic FX50 always shows more advantages, either 28mm wide angle is stronger, or 3.0LCD image quality is higher, or dual anti-shake function is better, animation function is the strongest, so the comprehensive performance is the best, which is the most outstanding at present.

1,. stylish appearance, compact size, easy to carry. FX50 continues the appearance of FX0 1, with an overall size of 97×57×25 mm, black, silver and pink can be selected, and it is made of matte material, which has a first-class anti-slip effect. It feels good and comfortable to hold. It may be much better than those models with the thinnest first and the thinnest second. Its menu design is reasonable, its operation is convenient and its performance has reached a high level. The more you look at the mold, the more you look at it. The solemnity reveals the fashion, and there is no lack of atmosphere in the middle school.

2. Equipped with a 3-inch 230,000-pixel display, it is the first model of Panasonic FX series to use a 3.0 large screen, and the effect is quite excellent when taking pictures. Using SD card, MMC card and SDHC card as memory card media, charging with 1 150mAh lithium battery can take about 300 photos at a time.

3.FX50 adopts 7.38 million pixels 1/2.5-inch CCD, and its focal length is equivalent to 3.6 times of the optical zoom Lycra lens of traditional 35mm camera 28- 102mm. Support ISO3200 high sensitivity, shutter range up to 60 seconds. The image processor is the latest "Venus III". Macro 5cm.

4. The 4.FX50 adopts Panasonic's unique MEGA OIS optical anti-shake technology, and another major feature is that the "intelligent ISO control" technology (IIC technology) is applied for the first time in the world, that is, when the camera detects shake, it will automatically increase the ISO to obtain a higher shutter speed, which has dual functions of optical anti-shake and high ISO anti-shake.

5, animation, support 16:9 mode 848 x 480 pixels 30 frames per second shooting, super function, natural and clear animation effect.

6. Super optical zoom function. When the pixel is less than 3 million, the optical zoom multiple is 5.5 times. This is a very practical function: firstly, 3 million pixels are enough for ordinary families, and the lens size at this time is 28- 154 mm, which not only has a wide angle of 28mm, but also can shoot distant scenes.
