1, the size of the sensor CCD or CMOS, which is the key to the 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 the sensor. 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). In fact, the average family generally prints only 5 or 6 inches, and 3 million is enough. At present, almost all models of DC on the market are more than 10 million pixels, and you can buy DC without looking at pixels.

3, lens size. 3 to 20 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; If you want telephoto, choose more than 200mm; Do not go to digital zoom. Of course, it would be better to have a 28mm wide-angle and telephoto lens, which can be more suitable for shooting in various occasions and realize the wish of traveling all over the world in one mirror. At present, there are more and more models available.

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. At present, the display effect of the 3.0 inch 230 thousand pixel display screen is particularly good.
