What should I pay attention to when buying a SLR camera?

There are three main brands of SLR cameras on the market, Canon, Nikon and Sony, and their workmanship is acceptable.

1. Shake the camera before buying it and listen to the sound of loose parts. If there is, it must be a quality problem. No matter what the profiteers are quibbling about, replace them immediately;

2. Pay close attention to whether there is any deviation between the shot scene and the scene seen by the viewfinder. If there is, it may be that the pentaprism inside is crooked, or the photosensitive element is crooked, which is definitely a quality problem. Replace immediately;

3. There are dark spots and bright spots on the LCD. Contrast the strong light to see if there are colored stripes. If the serious problem is that the LCD screen itself has poor anti-noise ability, it can't be said to be a quality problem, but it looks annoying and has been replaced.

4. Also, check whether the data cable with camera works well, and try it with a computer. If it doesn't work, change the line immediately;

In fact, as long as you don't buy parallel cameras, the quality is guaranteed, and the most important thing is the battery. Some profiteers like to replace the original battery, get a product to make up for it, or directly replace it with a fake battery. Pay attention to this before buying a camera. As soon as you put forward the battery inspection, profiteers will not dare to change your battery camera as soon as they see that you are an expert.

That's all I can think of.
