My camera rx 100 will buzz, is it normal?

1 and Sony RX 100 are quiet under normal circumstances, and the buzzing is caused by vibration. Many people call it the "black card vibrating door";

2. The performance of the "vibrating door" is that the fuselage continues to vibrate slightly, and the degree of vibration can be felt by hands, similar to the hum of the motor. The shutter button may appear when it is in focus or out of focus. If the visual angle is changed during the vibration, the vibration may disappear, and some users are sometimes good and sometimes bad;

3. The "vibrating door" is caused by the poor quality of the motor that drives the lens to shift;

4. Suggest the landlord to carry out after-sales maintenance.
