Eleven arrived, and I plan to buy a card machine to travel. What kind of card machine do you think is the best?

for ordinary consumers, in fact, the performance of card machines on the market is not much different. There are some gaps in all aspects, but the cheapest camera is enough for daily life and travel. You can go to the counter and have a look at the real thing. You can buy whichever shape you like.

if you have to compare, I can tell you the meaning of several key parameters, and just compare them yourself according to your own needs.

1. The most important parameter is the CCD size, which is generally expressed by the reciprocal. The larger the size, the finer the image quality. For example, 1/1.8 CCD is better than 1/2.5 CCD. You can't see this, but it can be found in the packaging, manual and other places of the camera. This is a very important parameter, and it can also be found in the digital channels of major websites.

2. About the pixel size: 5 pixels is enough for daily 6-inch photos, so today's cameras are more than enough. If you like post-processing or use it for other purposes and need large-scale printing, the bigger the pixel, the better.

3. About zooming. Optical zoom magnifies the image through different combinations of lenses, without damaging the image quality. Digital zoom is to calculate the color of points that cannot be obtained by optical lens through the color of surrounding pixels, so the image quality is reduced, and the specific effect is similar to the effect of magnifying the image by 2% on a computer through the image viewing software. So just buy a camera and look at the optical zoom multiple. Digital zoom is totally useless.

4. The larger the ISO value, the stronger the shooting ability in dark environment. If you often need to shoot without turning on the flash (such as shooting babies and visiting exhibitions), you can choose a large ISO value. Otherwise, you don't have to think about this. Now the camera configuration is basically enough, and using too high ISO will also increase noise and reduce the picture quality.

5. If you know about photography and want to take more personalized photos, you can choose one with many manual functions, such as setting the aperture shutter manually and focusing manually. You can also buy an entry-level SLR if economic conditions permit, and the price is about 5, yuan. If you don't understand it, don't consider it.

6. lens parameters, if you like to shoot scenery, the shorter the focal length, the wider the shooting range. For example, an 18mm lens has a larger angle than a 25mm lens. Need to shoot 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 mode. Lithium batteries are small and easy to use, but there is no way out if there is no electricity when going out for a trip, so it is necessary to buy another battery. The advantage of using dry batteries is that you are not afraid of power failure wherever you go. You can consider buying a set of rechargeable batteries and chargers.

that's basically it. by comparing these parameters with your financial ability, you can basically determine which one you want. If each has its own advantages and disadvantages, it depends on which aspect you use most and which aspect is the most important.
