May I ask Nikon, Sony, Canon that brand of camera is good, what is the model, the price is about 150

For ordinary consumers, in fact, the performance of the card machines on the market is not much different. It is certain that there are some gaps in all aspects, but if you use it for daily life travel, the cheapest camera is also sufficient. You can go to the counter to take a look at the real thing, and you can buy whichever shape you like.

If you have to compare, I can tell you the significance of a few key parameters, just compare them yourself according to your own needs.

1.The most important parameter is the CCD size, which is generally expressed as a reciprocal, the larger the image quality, for example, the CCD of 1 is better than the CCD of 1. This is not visible, generally in the camera's packaging, instructions and other places can be found, this is a very important parameter, major digital channels can also be found.

2.Regarding the size of the pixels: 6 inches** for daily printing, 5 million pixels are enough, so the current camera is more than enough. If you prefer post-processing or other uses that require large prints, the larger the pixels, the better.

3.About zoom. Optical zoom is a combination of lenses to magnify the image without damaging the image quality.

Digital zoom calculates the color of dots that cannot be obtained with an optical lens by calculating the color of the surrounding pixels, so the image quality is reduced, and the specific effect is similar to the effect of magnifying the image by 200% on a computer. So it's okay to buy a camera and look at the optical zoom factor, digital zoom is completely useless.

The higher the value, the better the ability to shoot in dark environments. If you often need to shoot without flash on (e.g., photographing babies, visiting exhibitions), you can choose a large ISO value. Otherwise, you don't need to think about this, the configuration of the camera is basically enough now, and the use of too high ISO will also increase the noise, so that the image quality will decrease.

5.If you know photography knowledge and want to shoot more personalized, you can choose one with many manual functions, such as manually setting the aperture shutter, manual focusing, and the gate level SLR if the economic conditions allow, around 5000. If you don't know this, don't think about it.

6.The parameters of the lens, if you like to shoot landscapes, the shorter the focal length, the larger the shooting range. For example, an 18mm lens shoots at a larger angle than a 25mm lens.

If you 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 in size and easy to use, but if you run out of power when you go out for a trip, you can't do anything, so it is necessary to buy another battery. The advantage of using dry batteries is that you are not afraid of power failure when you go to the **, you can consider buying a set of rechargeable batteries and chargers.

That's basically it, compare these parameters and combine them with your economic ability, you can basically determine which one you want. If you have your own advantages and disadvantages, it depends on which aspect you use most often and which aspect is the most important.

The first floor is very comprehensive, but I specifically recommend a few cameras to you, don't buy Nikon's, I recommend Sony TX5, if you don't like periscope lenses, you can buy Canon ixus130 (Canon personally does not recommend it) Panasonic FH3. Of course, with a budget of 2000, you can buy the Sony TX9, the absolute king.

Canon S95, **2000 more. It's over your budget, but it works great!

This problem will be fought between Jia Fan and Ni Fan. Actually, it's all good. Sony is also good, but Sony's SLR is still slightly worse. Sony's advantage is in the so-called mirrorless, specifically the NEX-5N and NEX-7 are very good.

Objectively speaking (according to objective comparative reviews), the imaging of the Canon's entry-level DSLR (especially when shot with a regular JEGP instead of RAW) is better than that of the Nikon's entry-level level. However, some people think that the Nikon entry-level pullover (18-55) is slightly better than the Canon's, and others think that the Nikon SLR entry-level is stronger than the Canon entry-level.

Mid-range and high-end devices have their pros, but the Nikon D800E has the highest sharpness of any full-frame camera.

It is also necessary to say that many people in the country say that the Nikon Sharp Canon is soft and outdated, based on the experience of the film era. In addition to the lens, DSLRs also rely on sensors (the same film used to be, but now it is different), as well as color filtering and image processing within the camera. Nikon's digital imaging is recognized as soft, while Canon pursues crispness and sharpness.

There is no one good or one bad, only which one suits you. Canon's lens group is well-rounded, with a full range of lenses in the mid-price range. Nikon's good head is more expensive, and there are no medium lenses. As for the fuselage, just look at it yourself.

Actually, it's pretty much the same. It's all good. It depends on whether your friends and relatives have Canon or Nikon, so that the footage can be shared in the future.
