For ordinary consumers, in fact, the performance of card machines on the market is not much different. There are definitely some differences in various aspects, but for daily travel use, the cheapest camera is enough. You can go to the counter to look at the actual products and buy whichever one you like.
If you must compare, I can tell you the meaning of several key parameters, and you can compare them yourself according to your own needs.
1. The most important parameter is the CCD size. This size is generally expressed as a reciprocal. The larger the size, the more delicate the image quality. For example, a 1/1.8 CCD is better than a 1/2.5 CCD. This is invisible and can usually be found on the camera's packaging, manual, etc. This is a very important parameter and can also be found on the digital channels of major websites.
2. Regarding pixel size: For printing daily 6-inch photos, 5 million pixels are enough, so today’s cameras are more than enough. If you like to do post-processing or need large-size printing for other purposes, the larger the pixels, the better.
3. About zoom. Optical zoom uses different combinations of lenses to enlarge the image without damaging the image quality. Digital zoom calculates the color of points that cannot be obtained through the optical lens by comparing the surrounding pixel colors, so the image quality is degraded. The specific effect is similar to the effect of enlarging the image by 200% through image viewing software on a computer. So when buying a camera, just look at the optical zoom factor. Digital zoom is completely useless.
4. The larger the ISO value, the stronger the ability to shoot in dark environments. If you often need to take pictures without turning on the flash (such as photographing babies, visiting exhibitions), you can choose a higher ISO value. Otherwise, there is no need to consider this specifically. Current camera configurations are basically sufficient, and using too high an ISO will also increase noise and degrade photo quality.
5. If you know photography knowledge and want to take more personalized photos, you can choose one with more manual functions, such as manually setting the aperture, shutter, and manual focus. If financial conditions permit, you can also buy an entry-level SLR. The price is around 5,000. If you don’t understand this, don’t consider it.
6. Lens parameters. If you like to shoot landscapes, the shorter the focal length, the wider the shooting range. For example, an 18mm lens shoots at a wider angle than a 25mm lens. If you need to take pictures of small things, such as insects, trinkets, etc., look at the macro shooting distance, the shorter the better, for example, 1cm is better than 5cm.
7. Power supply method. Lithium batteries are small and easy to use, but if they run out of power while traveling, there is nothing you can do, so it is necessary to buy another battery. The advantage of using dry batteries is that you don’t have to worry about power outages wherever you go. You can consider buying a set of rechargeable batteries and chargers.
That’s basically it. By comparing these parameters and combining them with your financial ability, you can basically determine which one you want. If each has its own pros and cons, it depends on which aspect you use the most and which aspect is the most important.
