How to choose a digital camera? Selection method of digital camera

1 First, summarize the basic requirements for camera purchase. The most important thing is to determine the purpose of your digital camera purchase. If it is for daily use, it is enough to take photos of scenic spots or take selfies with a general card machine (in fact, mobile phones are basically competent now). If you prefer landscape photos, you can choose a camera or SLR that focuses on telephoto function. If it is a product photo of a shop, it will be better to choose a camera with good sensitivity and large sensor size. The sensor size of card machine is generally small, so SLR will be chosen (of course, post-processing is very important).

2. Optical zoom and digital zoom. Generally speaking, the optical zoom function of cheap cameras is not strong. But the scenery is long, and you need a telephoto to get a better composition. Therefore, people who like outdoor photography will naturally pay attention to its zoom, especially the optical zoom ability. The zoom function of some card machines is almost negligible (once the zoom photos are blurred seriously, low-end cameras are generally powerless). If you are a professional landscape photographer, you may also choose a SLR with a telephoto lens. Like the pike cannon in the picture below.

3, sensor size, in fact, the core difference between card machine and SLR lies in two points, lens and sensor size. People often ignore the sensor size and only focus on pixels. The general card machine is 1/2.3 inches, but the pixel can reach more than100000. The SLR pixels are almost even lower than the card machine, but the imaging effect is better. People who like night or dark photography pay special attention to this.

4. No matter how high the pixel of the camera is and how large the zoom is, its sensor size is 1/2.3 inches, indicating that its positioning is still an entry-level camera. So this is a more important starting point.

5. Lens parameters: The selection of lens parameters requires certain photographic knowledge, mainly involving focal length and aperture. I won't introduce this aspect in detail. Generally, the entry-level focal length mainly considers photography in some common occasions in life. If you need more choices, you will naturally choose a SLR camera with a replaceable lens.

6, pixels, pixels have always been the most concerned issue for laymen. However, pixel is indeed an important measurement parameter. Admittedly, the more pixels, the finer the details of the photo. However, it is worth mentioning that although the pixels of the card machine are the same as those of the SLR, many low-end camera photos will be blurred after being enlarged. Therefore, the pixel is generally a parameter that does not make much comparison. As long as it's not too low.

7, details, after you choose a certain camera, it is the evaluation of the details. For example, whether the evaluation response of other users is good. Do you like the appearance of this shape? And the presentation and price of accessories.
