Is the SLR camera easy to operate? Is it risky to buy a second-hand camera?

First of all, when I saw this problem, I thought the subject must be a photographer.

Since you are a photographer, it is not recommended to buy second-hand products, and the second-hand water of the camera is also very deep. If you don't know the situation, it is recommended to buy through formal channels.

Let me briefly explain that the reason why I use a camera is more like the pleasure of configuring my own parameters. Look at a landscape, think about composition, think about how appropriate the focal length is, adjust the parameters of the aperture shutter, and then see if the photos taken are exposed properly, and then retouch them with ps after returning home. This is my pleasure in photography.

So cameras and mobile phones, when it comes to taking pictures, are simple and difficult. Pick up the camera and press the shutter, and a photo will come out. However, because the camera does not have the post-adjustment of AI like a mobile phone, the straight photos are often not so pleasing.

Finally, if you just want to shoot the captain casually and don't want to learn the basics of photography, then buying a better mobile phone is enough. If you want to learn the basics of photography, you should at least understand the factors such as aperture, shutter and exposure, so it is more appropriate to buy a camera.
