When purchasing, you should try the camera yourself to see whether the camera button operation is flexible, whether it feels comfortable, whether the zoom is smooth, whether the focusing speed is fast and accurate, whether the menu is easy to understand, whether the response speed is fast, and whether the LCD is clear.
